Why Fontana Homes Have Their Own Plumbing Problems
Plumbing in the Inland Empire does not age like plumbing in other parts of the country. A local plumber who sees these patterns every week can find the cause faster and recommend a repair that lasts.
Hard Water Is Hard on Every Fixture
Fontana's water is hard, often 15 to 25 grains per gallon. That mineral content builds scale inside water heaters, clogs aerators and showerheads, and shortens the life of valves and appliances. Regular water heater flushing and a water softener are the best ways to protect your plumbing.
Older Homes, Older Pipes
Much of Fontana's housing was built between the 1960s and 1990s, so many homes still have original copper supply lines, aging drains and corroded fittings. Pinhole leaks and slow drains are early warning signs. Learn when to replace instead of patch in our guide to whole-house repiping in Rancho Cucamonga and Fontana.
Clay Soil & Seismic Movement
Expansive clay soil and regular small earthquakes stress underground lines and slab foundations, cracking sewer pipes and opening slab leaks that go unnoticed for months. A sewer camera inspection finds them early, and our guide explains how to find a hidden water leak before it gets worse.
Emergency Plumbing in Fontana
Burst pipes, sewer backups, gas smells and failed water heaters do not wait for business hours. If you have an active leak, shut off your main water valve and call us right away. We provide same-day service across Fontana, and our emergency plumbing page explains what to do while you wait.

Fontana Plumbing FAQs
How quickly can a plumber get to my Fontana home?
We offer same-day service in Fontana for most calls, including leaks, clogs and water heater failures. Call (909) 684-1915 and we will give you an arrival window.
Should I repair or replace my water heater?
If your water heater is more than 10 years old, leaks from the tank, or needs repeated repairs, replacement is usually the better investment. Newer problems like a failed thermostat or heating element can often be repaired. Our water heater repair and replacement page explains both options.
What causes slow drains in Fontana homes?
Common causes include grease, hair, mineral buildup from hard water and, in older homes, aging or root-damaged sewer lines. One slow drain is usually a local clog, while several slow drains at once point to a main line problem. Our sewer and drain team can clear the clog, and a camera inspection shows what is happening inside the pipe.
How do I know if I have a slab leak?
Warning signs include an unexplained jump in your water bill, the sound of running water when everything is off, warm spots on the floor, and damp flooring or baseboards. Read more about slab leak repair or call us to schedule leak detection.

A O Dowd Plumbing Inc. did an amazing job with the water heaters I needed repaired. The team was friendly and professional all around. They communicated well from beginning to end - even followed up to make sure everything was working well
I had some issues with my boiler and their website was very clear on their expertise in that boiler so I called right away. They were were a little outside my area so Jason spent 15-20 minutes over the phone walking me though how to diagnose and fix it myself. I was able to get it up and running.
