Signs you need this
Hard water is part of it
San Jose Water counts water above 120 parts per million as hard. Its own figures put its groundwater at 183 to 440 mg/L, imported surface water at 77 to 153 and mountain surface water at 84 to 198, depending on which source serves your street (San Jose Water). Those minerals build up in cartridges, aerators and valve seats, so a faucet here can start dripping or lose flow long before it looks old.
The EPA puts the average household's leaks at more than 9,300 gallons a year, and dripping faucets are one of the common ones.
With water this hard, a faucet can start dripping or lose flow long before it looks old.
Rebuild or replace
Most faucets can be rebuilt with a new cartridge or washer if the body is sound and parts are still made. When the body is cracked, the finish is gone or parts are no longer available, replacing the faucet makes more sense. Either way, we tell you which it is and the price before we start.
Low flow at one faucet is usually a scaled aerator or cartridge. Low pressure at every faucet is a different problem, often the supply line, and that is water line repair. If scale keeps coming back, a water softener is the longer fix. Toilets have their own page: toilet repair.
