Toilet Installation and Repair in Temecula
A running toilet is the most common leak in a Temecula home, and one of the cheapest to fix.
The EPA's WaterSense program says a leaking toilet can waste about 200 gallons a day. On a tiered water budget like Rancho California Water District's, that alone can move a household into a higher price tier.
Most toilet problems here come down to two things: rubber parts wearing out on chloraminated imported water, and household pressure that is too high.
Toilets by the numbers
200 gal/day
From one leaking toilet
EPA WaterSense estimate.
1.28 gpf
California maximum
Maximum flush volume for new toilets sold in California.
1.6 to 3.5+
Older toilets (gpf)
Many pre-1994 toilets used 3.5 gallons or more per flush.
80 psi
Code pressure limit
Above this, a PRV is required. High pressure wears fill valves.
Why toilets run in Temecula
Imported water from the Metropolitan Water District is disinfected with chloramine, which is effective and safe to drink but slowly breaks down ordinary rubber. Flappers soften, warp and stop sealing. Chloramine-resistant flappers last longer. High street pressure on hillside lots also pushes past fill valve seals. If more than one toilet runs, test the pressure before replacing parts.
Test for a silent leak
Put a few drops of food coloring in the tank. Do not flush for 15 minutes. If color shows up in the bowl, the flapper is leaking. If water is running into the overflow tube, the fill valve is set too high or failing.
Replacing a toilet
New toilets sold in California are limited to 1.28 gallons per flush. A good modern 1.28 gpf toilet clears better than most 1.6 gpf models from the 1990s. Ask for a high MaP score if flush performance matters to you. We remove and haul away the old one, set the new one on a new wax ring or wax-free seal, replace the supply line and angle stop if needed, and check the flange.
Selling a home built before 1994? California Civil Code requires noncompliant plumbing fixtures to be replaced with water-conserving fixtures in many situations, including some sales and remodels.

Questions Temecula homeowners ask
Straight answers to the calls we get most. If yours is not here, call and ask. There is no charge for a phone conversation.
Call (951) 744-8310Why does my toilet keep running?
Most often a worn flapper. In Temecula, chloramine in imported water speeds up rubber wear.
Is it worth replacing an old toilet?
If it uses more than 1.6 gallons per flush or keeps clogging, yes. A modern 1.28 gpf toilet saves water and usually flushes better.
How do I know if the wax ring failed?
Water or a sewer smell at the base, or a toilet that rocks. Reset it promptly to protect the subfloor.
Can high water pressure make my toilet run?
Yes. Pressure above 80 psi pushes past fill valve seals. Have a plumber test it.
