Most Fontana toilet calls are about a flapper or fill valve that will not seal, a leak at the floor or a clog in the trap. If you need to stop the water fast, Fontana Water Company asks customers to use their own gate valve, not the company's angle stop or meter valve at the meter. Call the number on this page to be connected with a local plumber in Fontana.

What happens when you call
The number on this page connects you with an independent plumber who works in Fontana. Expect a few quick questions: is the toilet running, leaking, clogged or loose; has water reached the floor or a room below; and are other drains slow? A running tank is usually booked as a regular visit, while an overflow or a backup in several fixtures is handled sooner. On site, the plumber checks the tank parts, the supply line and stop, the seal at the floor and, if needed, the drain beyond the toilet.
Fontana Water Company notes that the angle stop and meter valve at the meter belong to the company and that customers should shut off water at their own gate valve. Knowing where that valve is before the plumber arrives saves time if the toilet stop behind the bowl will not close.
Cost factors
- The failed part: flapper and fill valve jobs are shorter than resetting the bowl.
- Floor work: a broken flange or wet subfloor adds parts and labor.
- Shutoff and supply: a seized stop or worn line is usually swapped during the visit.
- Clog location: a toy in the trap is fast; a blockage in the line to the street needs more equipment.
- Replacement: a cracked tank or bowl means a new toilet.
- Time of day: nights and weekends usually cost more.
Local conditions in Fontana
Water in Fontana depends on the address. Fontana Water Company is the main provider, but Cucamonga Valley Water District, West Valley Water District and two mutual water companies, Marygold and Crawford Canyon, also serve defined areas. The City suggests calling Fontana Water Company first if you are not sure who serves you, at (909) 822-2201. Its supply includes Lytle Creek water and groundwater from several basins, the kind of mix that leaves scale on tank parts over time.
Sewer is simpler. The City of Fontana collects and bills for sewer, at (909) 350-7670, and the Inland Empire Utilities Agency treats the wastewater. A clog between your toilet and the City main is private. The median home here was built in 1989, so many toilets and stops are original or close to it.
Before the plumber arrives
- Find your home's own gate valve and make sure it turns
- Stop using the toilet and any drain that backs up into it
- Lay towels down and move rugs or boxes out of the way
- Note when the problem started and anything that was flushed
- Clear a path to the bathroom and any cleanout outside
