Glossary terms
Open glossary →Biofilm
The slimy layer of bacteria, soap residue, and organic matter that coats damp, rarely-disturbed surfaces: the inside of drains, washing machine gaskets, and detergent drawers. It regrows quickly after chemical treatments, which is why physically removing it beats trying to dissolve it.
GlossaryCanister valve
A flush valve design (common on Kohler toilets) where a tall plastic cylinder lifts straight up instead of a hinged flapper tipping open. Canister toilets take a replacement seal ring, not a flapper. No flapper will fit one.
GlossaryDoor gasket
The folded rubber seal around a front-load washing machine door. Its inner fold holds water and lint by design, which makes it the number-one spot mold grows in a smelly washer. Pull the fold back and the gray-black line is the culprit.
GlossaryDoor sweep
The strip of rubber or bristle attached along the bottom inside face of an exterior door to close the gap above the threshold. Screw-on aluminum sweeps with slotted height adjustment outlast stick-on ones, and the blade should just touch the threshold. A dragging sweep tears itself off within a month.
GlossaryDrain filter
The lint trap behind the small panel at the bottom front corner of a front-load washer. It catches coins, hair ties, and lint before the drain pump, holds a cup or two of stale water, and is the most commonly missed step when cleaning a smelly machine.
GlossaryDrain snake
A flexible cable or barbed strip fed down a drain to hook and pull out clogs beyond finger reach. For bathroom sinks, a $3–$5 plastic zip strip handles the hair mat at the stopper; a 25-foot hand-crank cable auger ($25–$40) reaches clogs deeper in the branch line before it's time to call a plumber.
GlossaryDye test
The 15-minute diagnostic for a leaking toilet flapper: drop food coloring or a dye tablet into the tank water, wait without flushing, and check the bowl. Color reaching the bowl means water is sneaking past the flapper. The seal is done.
GlossaryEtched glass
Glass whose surface has been permanently altered by long-term mineral deposits or harsh cleaners. Etching looks like haze that no cleaner removes, because the damage is in the glass, not on it. Polishing compounds can improve it; prevention (a squeegee habit) is the real fix.
GlossaryFaucet cartridge
The replaceable valve unit inside most modern faucets, a plastic-and-brass cylinder that controls flow and temperature as the handle moves. When a faucet drips, the cartridge's internal seals are worn; swapping the cartridge ($10–$20, brand-specific) is the standard fix, and the faucet body itself almost never needs replacing.
GlossaryFeathering
Blending the edge of paint or filler into the surrounding surface with an almost-dry brush or light sanding, so there is no hard line where the repair ends. Feathering is what makes a touch-up invisible at conversation distance, which is the standard walls are actually judged by.
GlossaryFill valve
The vertical valve inside a toilet tank that refills it after a flush and shuts off when the float reaches the set water level. A fill valve that won't hold a consistent level has a failing internal seal; replacement valves cost $12–$18 and install hand-tight.
GlossaryFlapper
The hinged rubber seal at the bottom of a toilet tank that lifts when you flush and seals the tank shut while it refills. Because it sits in treated water around the clock, it hardens and warps on a schedule, and a worn flapper is the single most common cause of a running toilet. Flappers come in 2-inch and 3-inch sizes, and the wrong size physically cannot seal.
GlossaryFlow restrictor
The small plastic disc inside a shower head that caps output at the federal 2.5-gallon-per-minute limit. It's often blamed for weak showers, but a shower that used to be strong and faded is almost always scaled-up nozzles, not the restrictor. The restrictor never changes, so it can't explain pressure that got worse over time.
GlossaryGFCI outlet
A ground-fault circuit interrupter: an outlet that compares the current flowing out with the current coming back, and trips in a fraction of a second if any is leaking to ground. Code requires them near water: bathrooms, kitchens, garages, laundry rooms, and outdoors. One GFCI can protect a chain of ordinary-looking outlets downstream, which is why a dead bedroom outlet is sometimes fixed by a Reset button in the garage.
GlossaryHard water
Water carrying dissolved calcium and magnesium minerals, common across large parts of the U.S. When droplets evaporate, the minerals stay behind as white carbonate scale: the film on shower glass, the crust that clogs shower head nozzles, and the deposit on toilet fill hardware. Acids like vinegar dissolve it; detergents mostly do not.
GlossaryHinge pin
The metal rod that drops down through the interlocking knuckles of a door hinge and acts as the axle the door swings on. Tap it up from below to remove it. Squeaks live between the pin and the knuckle bore, so lubricant has to reach the pin itself.
GlossaryJoint compound
The gypsum paste ("mud") used to tape drywall seams and skim large patches. It goes on in thin coats, shrinks as it dries, and expects two or three passes a day apart, which makes it the right tool for big repairs and the slow, wrong tool for nail holes, where spackle wins.
GlossaryMERV rating
Minimum Efficiency Reporting Value: the standard 1–20 scale for how effectively an HVAC filter traps particles. MERV 8 catches dust and pollen; MERV 11–13 adds smoke, smog, and most allergens. The catch is resistance: the finer the filter, the harder the blower has to pull air through it, and a residential system forced through a filter it was not designed for runs longer, wears faster, and can even freeze the coil.
GlossaryO-ring
A ring of rubber seated in a groove that seals two parts against water or air when they compress it. It is the workhorse seal inside faucet cartridges, spray heads, and garden-hose fittings. O-rings fail by hardening and cracking with age, and a failed one shows up as weeping around a joint rather than a steady drip.
GlossaryOverflow tube
The open vertical tube in the middle of a toilet tank that drains excess water into the bowl if the fill valve overfills. It's the tank's failsafe: if water is trickling into its open top, the water level is set too high or the fill valve is failing.
GlossaryP-trap
The U-shaped pipe under a sink that holds a small plug of water to block sewer gas from rising into the room. It unscrews by hand at two slip nuts, which makes it the easy access point for clogs that sit below the drain opening.
GlossaryPivot rod
The thin metal rod that enters the back of a bathroom sink drain at an angle and connects the lift knob to the pop-up stopper. Unscrew its retaining nut and pull the rod out, and the stopper lifts free. That is the first step of clearing most sink clogs.
GlossaryPop-up stopper
The metal plug in a bathroom sink that opens and closes with the lift knob behind the faucet. Its base is where hair and soap scum anchor. The mat wrapped around it is the cause of most slow bathroom sinks.
GlossaryPressure regulator
The bell-shaped valve near a home's main water shutoff that reduces street water pressure to a safe household level, typically 40–60 psi. A failing regulator shows up as suddenly weak (or suddenly harsh) pressure at every fixture in the house at once.
GlossaryPTFE tape
Thin white thread-sealing tape (often called Teflon or plumber's tape) wrapped around threaded plumbing connections so they seal without leaking. Wrap two to three turns in the direction the nut tightens, and always strip old tape off before applying fresh.
GlossaryShutoff valve
The small valve on the supply line under a sink, behind a toilet, or beside an appliance that cuts water to that one fixture, so a repair does not mean shutting down the whole house. Turn it clockwise until it stops, then open the fixture to drain the last of the pressure before any plumbing work.
GlossarySpackle
Lightweight filler paste for small wall repairs. It presses into nail holes, dries in 30–60 minutes, barely shrinks, and sands smooth with a light touch. For holes under half an inch it needs no tape or backing. Some formulas go on pink and dry white as a built-in timer.
GlossaryStick-slip
The physics behind a squeak: two dry metal surfaces alternately gripping and releasing hundreds of times per second, fast enough to become an audible tone. A film of grease with body (lithium or silicone) keeps the surfaces apart, which is why it silences a hinge and thin penetrating oils only pause it.
GlossaryWeatherstripping
Compressible sealing material (foam tape, silicone bulb, or metal-backed V-strip) installed around a door or window frame so the closed door squeezes it and blocks airflow. Foam is cheapest and fades in a season or two of heavy use; silicone and V-strip cost a few dollars more and last years on an exterior door.
GlossaryWhite lithium grease
A thick, white, long-lasting grease made for metal-on-metal contact: door hinges, garage-door tracks, latch bolts. Unlike penetrating oils such as WD-40, which are solvents that evaporate within days, lithium grease has enough body to stay between the moving surfaces for years, which is what actually keeps a hinge quiet.
