In Upland, a shower that drips with the handle off, surges in temperature or turns stiffly usually has a cartridge or seal set that has worn out. A plumber can often replace it without opening the wall; a cracked body or obsolete valve calls for replacement. Call the number on this page to be connected with a local plumber in Upland.
Signs the valve needs work
- A slow drip or trickle after the handle is closed
- Temperature bouncing when a toilet refills
- A handle that turns past where it used to stop
- Low flow at the showerhead while other fixtures are fine
- Moisture or stains in the wall or ceiling near the shower
Local conditions in Upland
The City of Upland Public Works Department supplies water. About 80 percent of customer needs come from local groundwater pumped from City wells and from San Antonio Water Company and West End Consolidated Water Company wells. San Antonio Canyon surface water and imported State Water Project water make up the rest. Upland's water quality report lists the hardness, and groundwater-heavy supplies in this region commonly leave scale, and in a shower valve that scale settles on cartridge seals and inlet screens.
Upland's Utilities Division focused its service line inventory on homes built before 1987, a reminder that a good share of the city's housing is older. Homes from that period can have two-handle valves or first-generation single-lever valves. Some can be rebuilt; others no longer have parts. Low flow at only the shower often comes from a clogged inlet screen or a partly blocked cartridge rather than from house pressure.
What affects the cost
- Cartridge or seal replacement compared with installing a new valve
- Whether the manufacturer still makes parts for your valve
- How much tile or drywall has to come off to reach the body
- Cleaning or replacing clogged inlet screens and stops
- Permits. The City of Upland Building and Safety Division accepts permit requests online only, through its Citizen Self Service portal.
