Toilet Repair in Corona, CA

Signs to watch for

• The tank refills by itself in short bursts during the night
• A steady whine or hiss from the fill valve
• Scale in the rim holes that leaves the flush weak
• Water on the floor after a flush, or caulk that keeps staining
• A bowl that wobbles or a loose seat bolt
• Repeated clogs from the same toilet

Local conditions in Corona

The City of Corona Utilities Department supplies water from a mix of city wells (much of it run through the Temescal Desalter), Colorado River water treated at the city's own plants and some State Water Project water. The latest report puts average hardness at 146 mg/L, about 8.5 grains per gallon, and classes it as hard, with readings from 7.2 up to 290 mg/L depending on the source. Minerals in that range leave deposits on fill valve ports and flapper seats.

Corona also disinfects with chloramine. Chloramine can make some rubber flappers and seals soften or swell sooner than they would otherwise, so a toilet that runs again a year after a repair is not unusual. Plumbers often choose parts rated for chloraminated water.

Pressure plays a part too. The City says pressure regulators are the customer's responsibility to replace when needed. When a regulator fails, high pressure can make a fill valve whistle, overfill the tank or push a worn supply line to its limit.

Cost factors

• Whether the fix is inside the tank or requires pulling the toilet
• Scale or chloramine wear that calls for a full set of tank parts
• Condition of the flange and the floor around it
• A worn shutoff valve or supply line found during the repair
• A failing pressure regulator that needs replacing too
• After-hours or weekend timing
