Quick answer
Why is my water heater not producing hot water?
On a gas tank, the most common causes are a pilot light that's gone out, a failed thermocouple or flame sensor, or a faulty gas control valve. On an electric tank, it's usually a tripped breaker, a failed heating element, or a bad thermostat. Tankless units often stop heating because of scale buildup or a venting or ignition fault. Most of these are same-day repairs.
Water Heater Repair
Fast, honest water heater repair
Most water heater problems come down to a handful of parts: the thermocouple or flame sensor, the gas control valve, the burner assembly, the heating elements and thermostats on electric units, the T&P relief valve, and the drain valve. Our plumbers carry the common ones, so a large share of repairs are finished on the first visit.
Los Angeles water is hard, which matters for water heaters. Mineral sediment settles in the bottom of the tank, insulates the water from the burner, and causes the rumbling and popping many people hear. On tankless units, scale coats the heat exchanger and triggers error codes. A flush or descale often restores performance on its own.
We'll always tell you the honest math. If your tank is leaking from the body, is past its expected life, or the repair would cost a big share of a new unit, we'll say so and quote water heater replacement alongside the repair. If a cheap part will give it years more, we'll fix it and move on.

Honest pricing
How much does water heater repair cost?
Every job is different, so we don't guess over the phone and then change the number on site. We look at the problem, then give you a written flat-rate price before any work starts. The price you approve is the price you pay — and it's the same at 3 a.m. on a Sunday as it is on a Tuesday afternoon.
What affects the price:
- Which part has failed and whether it's on the truck
- Gas, electric, or tankless — and the brand and model
- Access to the unit (closet, attic, garage, or exterior)
- Whether flushing, descaling, or venting work is needed
Real customers
What homeowners say after the rescue.
Our reviews come from real emergencies — and how we handled them.
Emergency Sewer Backup
“We had a sewer backup on a Sunday night — our laundry room was completely flooded. I called Rooter Rescue at 9 PM and they had a tech at the door within 45 minutes. He cleared a major root intrusion in the main line and had everything flowing again by midnight. I couldn't believe the response time. They're the only plumber I'll ever call.”
Sarah M.

Slab Leak Detection
“My water bill had been climbing for months and I couldn't figure out why. Rooter Rescue used electronic detection equipment to find a slab leak under my kitchen floor without ripping up a single tile — found it in under an hour. The repair was clean, fast, and came in exactly at the estimate. These guys are total pros.”
Mike T.
Los Angeles, CA
Water Heater Replacement
“My water heater died on a Friday morning. I called three plumbers — two couldn't get to me until next week. Rooter Rescue had a new unit installed that same afternoon. The tech explained every option clearly, gave me a fair price without any pressure, and left the work area cleaner than he found it. Five stars isn't enough.”

FAQ
Water Heater Repair questions, answered.
Straight answers to what homeowners ask us most about water heater repair.
The usual culprit is a worn thermocouple or flame sensor, which tells the gas valve the pilot is lit. A dirty pilot orifice, a draft near the unit, or a failing gas control valve can also cause it. Replacing a thermocouple is a quick, inexpensive repair.
