The two hoses that feed a washing machine are under household water pressure every minute of every day, whether or not the machine is washing anything. A drain hose only carries water while a pump is working; a fill hose is loaded all the time, and when one lets go the water does not stop until somebody closes the tap. That is why a burst washer hose is one of the commonest large domestic water claims, and why the failure is so unfair: it is driven by age and by rubber that has hardened out of s

https://fixchecklist.com/p/prevent-frozen-pipes-in-a-cold-snap/2026-08-12T00:00:00Z

Demand for this page arrives on a forecast, which is the worst possible moment to start reading. So it is written in the order the cold arrives: find the shut-off valve first, prepare the house second, get through the cold snap third, and deal with a pipe that has already frozen last. The order is deliberate. The advice everyone repeats — leave a tap dripping — is the last measure on the list, not the first, and it does nothing for a pipe in a draughty crawl space that nobody has ever insulated.

https://fixchecklist.com/p/find-where-a-water-heater-is-leaking/2026-08-12T00:00:00Z

Water on the floor under a water heater is not one fault. It has six common origins and they do not have the same answer. Condensation is not a leak at all, and A. O. Smith's own gas guide says so in as many words: "Condensation is not a leak and will go away once the tank reaches normal operating temperature." A wet pipe connection at the top is the usual finding rather than the unusual one, and the same manufacturer's installation check states that "Almost all leaks occur at connections and ar

Every water emergency starts with the same instruction: turn off the water. That instruction assumes two things most households have never checked — that somebody knows where the main shut-off valve is, and that the valve still closes. Neither is safe to assume. FEMA's community preparedness handouts put "locate and label main water cutoff" on the outage checklist for exactly this reason, alongside a reminder to keep any special tool it needs stored nearby. A valve that nobody has turned in fift

Water sitting in the bottom of a dishwasher after a cycle is not always a fault, and that is the first thing worth knowing. GE Appliances says that on its dishwashers without an ultra fine filter, one to two cups of clean water covering the bottom of the tub is normal, and that on models with one, water in the filter area is normal but should not cover the tub floor. Whirlpool's own troubleshooting reads the same sight differently and treats water slightly above the filter screen as a sign of a

https://fixchecklist.com/p/clean-or-replace-a-vacuum-filter/2026-08-12T00:00:00Z

A vacuum cleaner that has lost suction usually has a clogged filter, and most machines have two or three of them in places the owner has never opened. This page walks you through finding every filter, taking it out safely, and deciding what to do with it. That decision is the whole job, because some filters are washed and some are destroyed by water, and the machine gives you no warning either way. This page does not tell you to wash your filter, and that is deliberate. Of the four manufacturer

A fire extinguisher is one of the few safety devices in a house that gives no signal when it stops working. It loses charge slowly, its seal gets snapped by a knock, or it quietly ends up behind the recycling bin where nobody can reach it in the ten seconds that matter. This page is the walk-round: the gauge, the safety pin, the tamper seal, the label, the cylinder and the place it is kept. It needs no tools and it does not ask you to take anything apart. It is not a page about putting a fire ou

A GFCI receptacle is the outlet with the TEST and RESET buttons on its face, and it almost never protects only itself. CPSC describes a receptacle-type GFCI as protecting whatever is plugged into it and other electrical outlets further down stream in the branch circuit, and Leviton's own installation leaflet adds the part that catches people out: those protected outlets can be in different rooms. Nothing on the face of a protected outlet has to say which device controls it. That is why a dead ou

A surge protector is the power strip you bought because the box said surge protector, and the thing almost nobody is told about it is that it does not stop working the way a light bulb stops working. The protective parts inside are consumable. They take the hit, they wear, and one day they are finished — and depending on how your particular unit was designed, the outlets may go on delivering power exactly as before. NIST's consumer guide says so plainly: some protectors cut the output power off

https://fixchecklist.com/p/winterize-a-garden-irrigation-system/2026-08-04T00:00:00Z

An underground irrigation system drains water from its pipes in one of three ways: a manual drain valve you open by hand, an automatic drain valve that opens on its own, or a compressed-air blow-out. Rain Bird's own guide says some properties use a combination — a manual valve on the mainline and automatic valves on the lateral lines running out to the heads. This page covers the first two methods: finding your drain valves, shutting off the water supply, draining the mainline and the backflow p

https://fixchecklist.com/p/use-a-pressure-washer-detergent-injector/2026-08-04T00:00:00Z

A pressure washer that will not spray soap has not necessarily failed. On most machines the detergent only draws through a dedicated low-pressure nozzle, usually black and marked Soap or Detergent, and every other nozzle on the machine will not draw it at all. Sun Joe's own manual for the SPX3000 states this directly: install the correct Soap nozzle, and all of the other coloured nozzles will not work for detergent application. Generac's gas-powered machines use a different mechanism, a siphon t

https://fixchecklist.com/p/unblock-a-pressure-washer-nozzle-and-inlet-screen/2026-08-04T00:00:00Z

Pressure that drops off, a spray that surges, or a pattern that sprays sideways usually comes from one of two cheap parts: the nozzle or the water inlet screen. Both are consumables the manufacturer expects an owner to remove, and neither holds water once the machine is off and the trigger has released the pressure. Briggs & Stratton's own troubleshooting guide lists a clog in the nozzle, the hose, the gun or the wand before it lists a pump fault. This page clears the nozzle hole and the inlet s

A private well is not covered by the rules that protect public water systems, and no government agency tests it for you. Testing on a fixed schedule is the only way to know whether your well water is safe to drink. Bacteria, nitrate, arsenic and radon can all be present with no color, taste or smell to warn you. This page covers a fixed annual and three-year testing schedule, situations that call for testing sooner, and how to read a laboratory result. It does not cover well repair or water tre

https://fixchecklist.com/p/tell-a-metric-hex-key-from-an-imperial-one/2026-08-04T00:00:00Z

A hex key or hex socket is sized by the flat-to-flat width of its tip, and that width comes from two unrelated systems: whole or half millimetres, or fractions of an inch. Several sizes in the two systems sit close enough that a key from the wrong system can slide into a fastener and feel almost right. A 5/32 inch key is only 0.03 mm from a 4 mm fastener; a 5/16 inch key is only 0.06 mm from an 8 mm fastener. That gap is smaller than a human hair. Force the wrong one and it can ride up on the co

A chirp and an alarm are not the same thing, and mixing them up is how people either evacuate over a dead battery or, worse, ignore a real fire. A chirp is a short, repeating sound the device uses to ask for something: a battery, a clean sensor, or, eventually, a whole new unit. A full alarm is loud and continuous, and CPSC's guidance for that sound is simple: leave the home immediately and do not stop to investigate. This page is for the chirp. It walks through finding which alarm in the home i

An in-ground irrigation system sits full of trapped water and empty pipe over winter, and both Rain Bird and Hunter Industries publish the same core warning for starting it again: open the supply valve slowly. A valve opened too fast sends a pressure surge, called water hammer, through pipe that has been empty, and both manufacturers say this can burst a pipe or damage a valve. This page walks through a spring start-up in that order — checking that the soil is no longer frozen, checking the valv

Every dehumidifier carries a pint-per-day number, and matching that number to your room takes two facts: the room's floor area and how damp the room is without a dehumidifier running. ENERGY STAR publishes a chart that crosses two room-size groups with three dampness levels to give a recommended pint range. This page walks through measuring the room, judging its condition, and reading that chart, then helps you decide between a portable unit and a whole-home, duct-connected system. The trap is

A refrigerator that has just been delivered or carried between rooms should not go straight onto power. The compressor holds a small reservoir of lubricating oil, and if the unit was tipped or laid on its side, that oil can end up in the wrong place. Switch it on too soon and the oil can strain or damage the compressor before the refrigerator has run a single cycle. Every major manufacturer publishes a recommended standing time to let the oil settle back — the disagreement is in the number. Sea

A stand mixer beater that sits too high leaves flour and butter unmixed at the bottom of the bowl. A beater that sits too low hits the bowl, chips the white coating off the beater, and can wear the bowl finish. KitchenAid designs a single small screw into most of its mixers to fix both faults, and names it the beater height adjustment screw. This page uses only KitchenAid's own published instructions and gives the visual check method they publish: unplug the mixer, turn the screw a small amount

A programmable or smart thermostat can hold a different target temperature at different times of day, so the heating or cooling system runs less while nobody needs it. Setting the schedule itself usually takes ten to twenty minutes once you know the times and temperatures you want. The menu names and the buttons are different on every brand, so this page gives the steps in the order every schedule menu uses and sends you to your own thermostat's guide for the exact button. ENERGY STAR reports t

A pressure washer has two engines' worth of oil to think about, and most owners know only one of them. The engine has its own oil, and the high-pressure pump bolted to it often has a separate oil of its own, sealed inside a small crankcase behind the wand connection. On many consumer machines, especially electric ones, that pump oil is sealed at the factory and is never meant to be opened. On others, mostly gas machines with a Triplex or plunger pump, the pump has its own fill point, drain plug

An automatic ice maker that has stopped delivering ice usually comes down to one of five things: the ice maker's own on/off control, the water supply to it, an overdue water filter, a freezer that is running too warm, or a refrigerator that was installed too recently to have finished its first cycles. None of the five needs a technician to check, and working through them in this order — control, water, filter, cold, install date — mirrors how the four manufacturers checked for this page approach

Most washing machines built in the last several years have a second cycle, separate from a normal wash, whose only job is to clean the machine itself. Whirlpool and Maytag call it the Clean Washer cycle. GE calls it Basket Clean or Self Clean. LG calls it Tub Clean or Tub Sterilization. Samsung calls it Self Clean, Self Clean+ or Pure Cycle. Whatever the name, it runs a longer, hotter wash with an empty drum to strip out the detergent film, lint and mold that a normal load never touches. This p

An inkjet printer builds its ink pattern with hundreds of tiny nozzles, and a nozzle check pattern is the fastest way to see whether any of them are blocked. This page walks through printing that pattern, reading it, cleaning the print head only when the pattern shows a fault, and printing the pattern again to check whether cleaning worked. The method is the same on almost every maker's printer: print, read, clean if needed, print again, compare. What this page will not do is print one universa

Most cars, trucks and SUVs carry a maintenance reminder — a wrench symbol, or a message such as Maintenance Required, Service Due, or Oil Life — that turns on once a preset mileage or a preset number of days has passed. Once the service is actually done, the reminder does not clear itself. An owner or a shop has to reset it, and the method is different for nearly every manufacturer and often for every model year. Some vehicles clear it with a button held through an ignition cycle, some from a me

A laser or LED-page printer gives two different low-supply messages, and they point at two different parts with two different jobs. A toner message (Toner Low, Replace Toner) means the powder that forms the printed image is running out. A drum message (Replace Drum, Drum Stop) means the light-sensitive roller that carries that image onto the page has reached the end of its rated life. The two parts wear at different rates, and readers who buy a replacement often buy the one the message did not n

An oven's interior light lets you check on food without opening the door, and like any light bulb it eventually burns out. It sits in a socket at the back or the side wall of the oven cavity, behind a small glass cover that keeps grease away from the glass. Replacing it is a short job, but it is not the same as changing a bulb in a lamp: the socket needs a special appliance bulb, not a standard household bulb, and the oven must be cool and disconnected from power before you touch the socket.

A showerhead loses spray force over the years as mineral deposits clog its holes, or a household simply decides to cut its water use. EPA's WaterSense programme estimates that the average family could save about 2,700 gallons of water a year, and more than 330 kilowatt hours of the energy used to heat it, by fitting a WaterSense labeled showerhead. The mechanical part of the job is a short unscrew-and-rescrew onto the shower arm already in your wall. The part most people get wrong is the tape.

A multimeter that still reads voltage and resistance correctly but goes dead only on a current range usually has a blown internal fuse — the small cartridge fuse that protects the meter, and you, if something goes wrong while the meter is measuring current. This is the same problem people describe as a "multimeter fuse blown", a meter that "won't read amps", or one that is "dead on one range", and it is a straightforward fix once you have the exact replacement fuse your own meter calls for.

A key fob that only works when you are standing next to the car is usually a flat coin cell rather than a broken remote. Mazda's owner's manual lists a reduced operational range as one of the three signs that the key battery is low, alongside a flashing KEY indicator and a transmitter light that no longer blinks. Changing the cell is a five-minute job on a kitchen table. The two things that go wrong are buying the wrong cell and putting it in upside down, and both are avoidable if you read the o

Most major appliances sold in the United States carry a yellow-and-black EnergyGuide label: refrigerators, dishwashers, clothes washers, freezers, central air conditioners, furnaces, heat pumps, boilers, pool heaters, water heaters, room and portable air conditioners, and televisions. The label sits inside the appliance door, on the front of the appliance, or on the box, and it puts two things in front of a shopper: a dollar figure for the estimated yearly cost to run that model, and a yellow sc

Most passenger car tires sold in the United States carry three federal grades moulded into the sidewall: a TREADWEAR number, a TRACTION letter and a TEMPERATURE letter. Together they make up the Uniform Tire Quality Grading System, or UTQG, created by 49 CFR 575.104. This page shows exactly where to find each grade and what each one measures, using the wording of the regulation itself and NHTSA's own consumer material.

Your vehicle's Tire and Loading Information placard carries more than a tire pressure number. Federal regulation 49 CFR 571.110 also requires two figures about weight: how many people the vehicle is designed to seat, and a line that reads something like ‘The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.’ That second figure is the one that matters on a trip with a full car, luggage, and maybe a roof box. It sets the ceiling for everyone and everything you put in th

Every power tool carries a rating plate, and most owners never read past the model number. The same plate lists the electrical rating your tool needs to run, the speed the motor reaches with no accessory fitted, the biggest accessory the tool can safely take, and the marks that show how the tool guards you against electric shock. Reading it correctly is the one page every other power tool page on this site assumes you have already done. This page will not print a voltage, a current, a speed, or

A dashboard light shaped like an oil can, or carrying the words oil or engine oil, is not the same thing as a low oil level, a check engine light, or a wrench-shaped maintenance reminder. It reports one thing only: the pressure of the oil moving through the engine right now, measured by a sensor on the engine block. It says nothing about how much oil is sitting in the pan, which is what a dipstick measures, and a full dipstick does not rule out a pressure problem. This page tells you how to rec

A tape measure looks simple, but two things trip up almost everyone: the small marks between the inch numbers, and the metal hook at the end that wobbles. That wobble is not a broken tool. The hook is riveted with a small amount of built-in play, moved back and forward by a distance equal to the hook's own thickness, so a reading comes out the same whether you hook it over an outside edge or push it flat against an inside wall. This page shows how to read the whole-inch numbers and the fraction

Buying a range extender or a mesh node is the usual fix for a room the wifi does not reach, and it is also the step people get wrong most often. The instinct is to put the new device as far from the router as the cable or the outlet allows, on the idea that further away means more coverage. TP-Link's own instructions say the opposite: the device has to hear a strong signal from the router before it can rebroadcast one, so a spot too far away gives you a weak extension of a weak signal, or a mesh

A water hardness test strip gives you a fast, rough number for how much dissolved calcium and magnesium is in your tap water. Dip a strip, wait, and match its color to the chart on the container to get a reading in milligrams per liter (mg/L), parts per million (ppm), or grains per gallon (gpg). This page walks through collecting a fair sample, running the strip correctly, and reading the color chart without guessing between two blocks. It also explains what the number means, using the U.S. Geol

A speed test run once, over wifi, from whatever device was closest, answers a different question than the one your provider needs answered. It measures the radio link between that device and your router at that exact moment, with everything else in the house free to use the same connection. None of that is what your service agreement actually promises you, so a provider can reasonably say that a single low reading proves nothing. "My wifi feels slow" and "my internet service is under-delivering"

A pipe or a hose is sold and labeled by a nominal size, and a nominal size is a name for a product family, not a measurement of the object in your hand. A pipe marked half inch can measure five eighths of an inch across, a garden hose fitting marked three quarter inch is sized by an old thread standard rather than by a ruler across the opening, and the gap between the label and the measurement is different for every material. Buying a fitting from the label alone is one of the most common ways a

A home fire escape plan is a simple floor plan of your home that marks two ways out of every room, one meeting place outside, and the location of each smoke alarm. The U.S. Fire Administration says a household can have less than two minutes to get outside once a smoke alarm sounds, so a plan only helps if everyone already knows it. This page walks you through drawing that plan, then through running it as a real fire drill with every household member, including a drill at night. It draws on the U

A laser or LED-page printer builds an image with three parts working together: a toner cartridge, an imaging or drum unit, and a fuser. Any one of the three can fail on its own, and each failure looks different on the page. Print that is light or grey all over usually points at the toner cartridge or the imaging unit. A line or a streak that repeats in the same place on every page usually points at the imaging or drum unit. Marks that repeat down one page at an even spacing point at whichever pa

A laptop that runs hot and has a loud fan is usually one of three different problems wearing the same disguise. Fan noise that stays loud even with nothing running points to a blocked air vent or a background process. Fan noise that only appears during a demanding task, like a video call or a game, is the fan doing its job. Fan noise together with a sudden shutdown while the machine feels hot is a different, more serious fault, and this page routes you straight to the manufacturer for that one.

Every Ethernet patch cable has its category printed along the length of the jacket, usually as CAT5E, CAT6 or CAT6A. This page shows you where to find that print and how to read it, so you can settle the cat5e vs cat6 question for the cable already in your hand, instead of guessing from its color or its price. It also shows you how to check the link speed your equipment is actually using, so you can compare what the cable is rated for against what your network needs. This page will not print an

Two things identify a filter: the part number printed on its own frame or housing, and its own physical dimensions. Between them, they let you test any “compatible,” “generic,” or “will fit” claim before you spend money on a filter that turns out to be the wrong size or the wrong shape. This page covers HVAC and furnace filters, refrigerator and other water filters, cabin air filters, engine air filters, vacuum filters, and pool or spa filters — anywhere a reader stands in front of a wall of nea

A dead remote, a dead smoke alarm, or a dead flashlight usually comes with one clue: the tiny code printed on the old cell. That code is doing several jobs at once — it names the chemistry, it points to a physical size, and it implies a voltage — and two codes that look almost the same on a shelf can be genuinely different cells. Buying by a rounded label like “AA” or a guess at “the round one” is how the wrong cell ends up in a smoke alarm or a key fob. This page shows how to read the printed c

Sediment settles at the bottom of a storage water heater over time, and it is the most common cause of a rumbling or popping noise from the tank. This page walks you through draining a storage-type water heater, electric or gas, to flush that sediment out through the drain valve. It also covers refilling the tank afterward so you do not restore power to an empty tank. This page does not give lighting steps for a gas control: those steps differ by manufacturer and model and belong in your water

A washing machine ships from the factory with a set of transit bolts holding the drum still, and most installers remove them in the first hour and set them aside or throw them out. Years later the moving truck is booked and the bolts are gone. Whirlpool and GE Appliances both warn that a washing machine moved without its transit bolts refitted can suffer damage inside the suspension. This page is for that day: the drum still needs to be pinned still for the ride, and it walks through fitting the

A wet/dry vacuum, also called a shop vac, needs a different filter for a different job, and fitting the wrong one is the most common mistake owners make. Run water through the ordinary dry cartridge filter and it soaks through, clogs, and can let liquid reach the motor. Run fine dust, such as drywall dust or cold ashes, through it and the dust can pass straight through and blow back into the room. This page shows how to match the filter to the job — dry debris, fine dust, or liquid — and how to

Nobody looks up a car battery's age for fun. The question comes up when the battery is slow to start the engine, when a shop is checking whether it is still under warranty, or when someone buying a used car wants to know what they are getting. The trouble is that the label on the case usually carries more than one code, and only one kind of code is a date. A group size code tells a parts store which battery fits the tray, not when it was made. A cold cranking amps rating tells you how much start
