In Perris, a shower that won't shut off fully, jumps between hot and cold or has a sticky handle usually needs a new cartridge or seals, which a plumber can often install through the trim. A valve that is cracked or no longer supported gets replaced. Call the number on this page to be connected with a local plumber in Perris.

Perris water at a glance
Eastern Municipal Water District (EMWD) is the water provider for all of Perris. It already served most of the city and took over the former City of Perris water and sewer systems, so every Perris address is now an EMWD customer. Hardness, though, depends on which supply reaches your tap. EMWD's 2023 report lists Mills plant water at an average of 4.7 grains per gallon, Perris Filtration Plant water at 9.9, and its Perris Valley wells, which serve a limited area along Perris Boulevard near the Ramona Expressway, at about 20 grains per gallon. That last figure is very hard on EMWD's scale, and shower valves in that area can scale up noticeably faster. EMWD uses chloramine for final disinfection at its treatment plants, which has little to do with how a valve is repaired. Depending on the age of the house, a plumber may meet anything from a two-handle valve to a current single-lever model.
What to do now
- Shower won't turn off? Close the main shutoff valve for the house and leave it closed until the plumber arrives.
- Dripping only? Note how fast it drips and whether it is the head or the spout.
- Temperature swings? Avoid running other fixtures during showers, and test the water before stepping in.
- See any staining? Look at the wall behind the valve and the ceiling below a second-floor bathroom.
- Get a photo of the handle and trim so the brand can be identified.
Symptoms and what they usually mean
| Symptom | Likely cause |
|---|---|
| Drip from the head after shutoff | Worn cartridge seals or scaled seats |
| Handle stiff or gritty | Mineral buildup on the cartridge |
| Sudden hot or cold during a flush | Pressure-balance spool stuck |
| Weak flow at the shower only | Clogged inlet screens or cartridge ports |
| Spout and head running together | Diverter worn |
Cost factors
- Cartridge or seal kit versus a full valve replacement
- Parts availability for the brand installed
- Scale that locks the cartridge in place
- Tile removal and patching to reach the valve body
- Permits, issued by City of Perris Development Services - Building through its online portal, (951) 943-5003
For trouble on EMWD's side of the meter, the district lists 800.698.0400 for outages and trouble calls.
