The parts that wear out first are usually the small rubber and moving pieces, like toilet flappers, fill valves, faucet washers and cartridges, and appliance supply hoses. These parts are cheap compared with pipes, but when they fail they can waste water or cause leaks.
Toilet Parts
Flappers and fill valves often last only five to ten years. Chlorine and minerals in the water make rubber stiff and warped. A toilet that runs, refills on its own, or takes a long time to fill is often showing early signs of worn parts.
Faucet Parts
Faucets have washers, O-rings, or cartridges that control the flow of water. As they wear, faucets drip from the spout or leak around the handle. A slow drip may seem small, but it adds up over weeks and months.
Hoses and Connectors
- Washing machine hoses: rubber hoses can crack or bulge and should be checked often.
- Sink and toilet supply lines: braided lines last longer than old plastic or rubber ones, but they still age.
- Dishwasher and refrigerator lines: these thin lines can kink, crack, or loosen.
Other Common Wear Points
Shut-off valves under sinks and behind toilets can stiffen and drip. Water heater anode rods wear down as they protect the tank. Sump pump switches and check valves also wear with use. Caulk around tubs and showers breaks down and lets water slip behind tile.
Checking these parts once or twice a year takes only a few minutes and can prevent a bigger repair. Keep a note of when each part was last replaced.
Since toilets have several parts that wear out on their own schedule, fixing a toilet that runs or leaks is one of the most common repairs in any home. If you want a full list of what to watch in your house, you can ask our plumbers for a walk-through. JPR Plumbing answers at (833) 603-1840.
