Most San Clemente toilet repairs involve worn tank parts, mineral buildup from hard water, a failed seal at the base or a clog. Homes here date mostly from the 1980s, so the shutoff valve and flange under the toilet may also need attention. Call the number on this page to be connected with a local plumber in San Clemente.

Why does hard water keep crusting my toilet?
Hardness is the short answer. Water the City buys from Irvine Ranch Water District's Baker plant measures 293 mg/L, or 17 grains per gallon, and Metropolitan treated water comes in at 236 mg/L, or 14 grains, according to the City's latest water quality report. Every flush leaves a thin film of minerals behind, and over time that forms a chalky ring at the waterline, crust in the rim holes and scale on the fill valve. Clogged rim holes weaken the flush, and a scaled fill valve may not shut off cleanly. The City also uses chloramine, which can wear rubber flappers sooner than you'd expect. Homes in Talega or the small part of north San Clemente served by South Coast Water District get their water from those districts instead, so check their reports for hardness.
Who do I call if the toilet backs up?
If one toilet clogs and the rest of the house drains normally, it's a plumbing job inside your home. When several fixtures back up at once, the blockage is probably in the sewer line, and the question becomes whether it's on your property or in the public main. The City handles sewer for most of San Clemente, Santa Margarita Water District serves Talega and South Coast Water District covers a small part of the north end. Sewage coming up outside, in the yard or the street, can be reported to the City's water and sewer hotline at 949-366-1553.
Is water at the base always the wax ring?
Not always. A failed seal under the bowl is common, especially if the toilet rocks, but water at the floor can also come from a sweating tank, a leaking supply line, a loose tank-to-bowl connection or a crack in the porcelain. In a house from the early 1980s (the city's median home was built in 1982, per census survey figures), the flange may be corroded too. A plumber dries the area, then checks each point until the drip is traced.
Local note
Before hiring for a replacement, ask whether a permit is needed; plumbing permits in San Clemente go through the City's Community Development Building Division. If you're also fighting scale on faucets and shower heads, the toilet problem may be part of a larger hard-water question worth talking through with the plumber.
