Addresses in the City of Riverside are served by Riverside Public Utilities, or by Western Municipal Water District or Eastern Municipal Water District in a few areas, so most homes here do not have a private well pump. Well work is a rural-property topic, covering submersible pumps, pressure tanks, switches and control boxes. Call the number on this page to be connected with a local plumber in Riverside who can tell you whether your problem is a well issue and help you find the right service.
Straight talk about wells and Riverside
RPU supplies most of the city with groundwater it pumps from its own wells in the Bunker Hill and Riverside Basins. That is a public system, not a private one. The utility runs those wells, and a home on RPU service has no pump of its own. The same goes for addresses served by Western Municipal or Eastern Municipal. We do not have data on how many properties in the area use private wells, so we will not guess. If you have a private well on a rural lot, the information below applies.
Low pressure on utility water
If your bill comes from a water utility and pressure is weak, look at the house side. Common causes are a failing pressure regulator, a partly closed main valve, scale-clogged aerators or galvanized supply lines narrowed by corrosion. RPU rules require a regulator and relief valve where static pressure exceeds 80 psi, and an aging regulator can stick and starve the house.
Warning signs on a private well
- No water anywhere in the house.
- Pressure that rises and falls while one tap runs.
- A pump that clicks on and off in quick bursts.
- Air spitting from faucets, or grit and sand in aerators.
- An electric bill climbing for no clear reason.
Parts that usually fail
| Component | Typical symptom |
|---|---|
| Pressure tank | Short cycling from a lost air charge or a ruptured bladder |
| Pressure switch | Pump will not start or will not shut off |
| Control box | Pump hums but does not run, often a capacitor |
| Submersible pump or motor | Low output or no output at all |
| Check valve and drop pipe | Water drains back down and the pump restarts often |
Hard water and heat
Hard groundwater leaves scale that can foul pressure switch tubes and tank fittings. Equipment in sheds or full sun also runs hot through long summers, which is hard on controls and wiring.
Before anyone comes out
- Check the breaker for the pump.
- Note the pressure gauge reading at the tank.
- Open a tap and listen for the pump to start.
Leave electrical work and pulling the pump to a professional.
Cost factors
Cost depends on which component failed, well depth, pump size, access to the wellhead, and whether the tank or controls are replaced too.
