Aerator
An aerator is the small screened tip that screws onto a faucet spout, mixing air into the stream to soften the flow, cut splashing, and save water.
The aerator is the little fitting at the very end of a faucet spout. Inside it a fine screen and a flow restrictor break the water into a soft, bubbly stream by drawing air into it, which is why the water feels smooth instead of splashing out as a hard jet. It also sets the flow rate, which is how modern faucets meet water-use limits without feeling weak.
Homeowners notice the aerator when one faucet suddenly loses pressure while the rest of the house is fine. The screen catches grit, rust flakes, and mineral scale that travel through the pipes, and a clogged aerator is the single most common reason a single faucet runs slow. The fix is to unscrew the tip by hand or with pliers, rinse or soak out the debris, and screw it back on, a two-minute job that solves a surprising number of pressure complaints.
Aerators come in standard thread sizes and in styles that swivel, spray, or pause, and a low-flow model is an easy way to trim water use at a sink. If cleaning one does not restore the flow, the trouble is upstream, in the supply line, the shutoff valve, or the faucet cartridge.

- Wax Ring : A wax ring is the soft sealing gasket that sits between a toilet base and the floor flange, blocking water and sewer gas from escaping at the connection.
- Toilet Flange / Closet Flange : A toilet flange, or closet flange, is the ring that anchors a toilet to the floor and connects it to the drain pipe below, holding the bolts that clamp the bowl down.
- Fill Valve (Ballcock) : A fill valve, the modern replacement for the old ballcock, is the tank part that refills a toilet after a flush and shuts off when the water reaches the set level.
- Flapper : A flapper is the hinged rubber seal at the bottom of a toilet tank that lifts to release water into the bowl on a flush, then drops back to hold the tank full.
