When a pipe bursts in a Rialto home, close the house shutoff right away and keep away from any wet outlets, then have the ruptured length replaced. Water rising at the meter goes to whichever of Rialto's three water retailers serves your address. Call the number on this page to be connected with a local plumber in Rialto.

Which water company do I call if the leak is at the meter?
Rialto has three water retailers. The City's own system, Rialto Water Services, serves part of the city, and West Valley Water District and Fontana Water Company serve others, according to a City drought planning application. Your bill names your provider. Call that utility if water is surfacing at the meter box, the curb or the street, since those are generally its pipes. A break on the house side of the meter, or anywhere inside, is for a plumber you hire.
What usually makes pipes burst in Rialto houses?
True freeze damage is unusual here. Most failures come from:
- Flexible connectors at toilets, faucets, washers and water heaters that age and split
- Older copper or galvanized pipe that has thinned at bends and joints
- Pressure surges or high static pressure when a regulator isn't working
- Attic and garage lines baking through long summers
- Ground movement, including earthquakes, stressing pipe where it enters the slab
The City's own water system relies mainly on local groundwater, and like most of the region it tends toward hard water. Scale won't burst a pipe, but it can stiffen a valve you haven't turned in years.
Is a permit involved, and how is the repair handled?
The City of Rialto Building & Safety Division, part of Community Development, issues permits, with online applications through the City's portal. Splicing a short damaged section is often a simple repair, while rerouting or replacing larger runs is more likely to need a permit, and the plumber can tell you up front. The usual sequence is to find the break, cut out the bad piece, install new pipe and fittings, then turn the water back on gradually and check every nearby joint under pressure.
A quick Rialto note
Learn where your main shutoff is before you need it. In many homes it sits near a front hose bib or where the line enters the garage. If it is stiff or seized, ask the plumber to replace it during the repair so the next emergency is easier to stop.
