Published by Clément Lacaille, Tech-Bharat · Updated · How we research

Research page, not a site visit. Plumber Comparator is not a plumbing contractor and its editor is not a licensed plumber. Figures below are typical ranges and cited public data; your job needs a written quote from a CSLB-licensed C-36 contractor.

A plumber typically charges $150–$250 to replace a fill valve or flapper, $150–$350 to reset a toilet on a new wax ring, and $250–$800 to install a new toilet including haul-away. Most of the spread in the last figure is the toilet itself.

JobTypical priceSigns
Fill valve or flapper replacement$150–$250Tank refills on its own, runs constantly, slow refill
Reset on a new wax ring$150–$350Water at the base, rocking toilet, sewer smell
New toilet installed, old one hauled away$250–$800Cracked bowl or tank, old high-flush model

Typical California ranges, not quotes. If you supply the toilet, expect to pay labor only, but ask whether the plumber warranties customer-supplied fixtures.

The five-minute leak test

A running toilet can waste a lot of water without making much noise. Put a few drops of food coloring in the tank, do not flush, and wait 15 minutes. If color shows up in the bowl, the flapper is leaking. A worn flapper is a cheap part, and often a do-it-yourself fix.

Hidden leaks like this are exactly what utilities now catch with smart meters. Britton, Stewart and O’Halloran used high-resolution smart meter data from an Australian utility to identify leaks on the customer side of the meter and to help customers fix them quickly. If your utility offers a usage portal or leak alerts, a steady overnight flow is worth checking.

Repair or replace?

California rule on old toilets

California law treats any toilet manufactured to use more than 1.6 gallons per flush as a "noncompliant plumbing fixture" (Civil Code § 1101.3). For single-family homes, owners were required to replace such fixtures by January 1, 2017; when you pull a permit for alterations, noncompliant fixtures must be replaced before final approval; and sellers must disclose whether the home still has any (Civil Code § 1101.4). If your toilet predates the 1990s, a replacement may be both the practical and the compliant choice. Many water districts also offer toilet rebates; check yours before buying.
