Rainbow Municipal Water District rates its water as very hard, so scale is a frequent cause of noisy, slow or failing water heaters in Bonsall. Many of those units can still be repaired if the tank has not started leaking. Call the number on this page to be connected with a local plumber in Bonsall.

Bonsall water and water heaters
Most of Bonsall gets water from Rainbow Municipal Water District, which imports all of its supply from the State Water Project and the Colorado River, treated at Metropolitan's Skinner plant in Temecula. Rainbow's consumer confidence report gives average hardness of 230 mg/L, or 13.45 grains per gallon, and calls that very hard. In a tank heater, that mineral load becomes sediment that insulates the bottom of a gas tank from the flame and coats the elements of an electric one. The water is disinfected with chloramines. Some edges of Bonsall are served by other agencies, so check your bill. A showerhead clogging with white grit is often the first clue that the heater's tank is collecting scale as well, well before the heater itself starts making noise.
Fuel varies too. Many homes use SDG&E natural gas, while some rural parcels may rely on propane, and others are all-electric.
Repair or replace: a quick comparison
| Situation | Usually repair | Usually replace |
|---|---|---|
| Tank age | Younger unit, solid tank | Older unit with rust or repeated failures |
| Sediment | Flushes out cleanly | Hardened layer that won't drain |
| Leak location | Fitting, drain valve or relief valve | Tank shell |
| Electric elements | One element burned out | Elements failing again and again from scale |
| Gas controls | Thermocouple or igniter | Control valve on an aging, scaled tank |
Signs it is time to call
- Popping or roaring each time the burner comes on
- Hot water running out far sooner than it used to
- White, gritty flakes in faucet aerators or showerheads
- Water pooling around the heater base
- A pilot that keeps going out
Timing notes
A yearly flush suits Rainbow's very hard water, and a plumber can check the anode rod during the same visit, since it wears faster in some conditions. Heaters in detached garages and outbuildings on larger lots sit through hot summers and the occasional cold night, which stresses controls and exposed piping. If you smell gas, leave and call 911 and SDG&E at 1-800-611-7343, or 911 and your propane supplier for propane. Bonsall is unincorporated, so a replacement permit would go through the County of San Diego.
