Water Heater Repair You Can Trust in San Diego
No hot water, rusty or discolored water, strange popping sounds, or a puddle forming around your water heater are all signs your system needs immediate attention. Repipe Home Hero is a family-owned, C-36 licensed plumbing company serving San Diego County, and water heater repair is one of the most common calls we run. We work on every major brand — Rheem, Bradford White, A.O. Smith, Rinnai, Navien, State, and more — so you’re never told we “don’t service that model.” Every visit starts with a real diagnosis, not a guess, because the right repair depends on knowing exactly which component has failed.
Many water heater problems come down to a single failed part: a thermocouple that won’t hold a pilot light, a heating element that’s burned out, a faulty gas valve, a stuck pressure relief valve, or sediment buildup choking the tank. In most of these cases, a targeted repair solves the problem in a single visit at a fraction of the cost of a new unit.
If your water heater is older or showing multiple problems at once, we’ll walk you through your options honestly, including a full Water Heater Installation or a Tankless Water Heater Installation, with transparent pricing either way. If the issue is actually in your home’s supply lines rather than the unit itself, see our Plumbing Pipe Repair page for pipe-specific diagnostics and repairs. And if these water heater issues are one symptom of a broader pattern — aging pipes, recurring leaks, or low pressure throughout the house — it may be worth having us evaluate whether a whole house repipe makes more sense long-term than repeated repairs.
Minor Fix, Major Repair, or Full Replacement?
Minor Repair
When a single part has failed — a thermocouple, thermostat, or pilot assembly — on an otherwise healthy unit, we replace just that component and get your hot water back the same visit.
Best for: units under 8 years old with one isolated issue.
Major Component Repair
Problems like a failing heating element, a leaking gas valve, or a corroded pressure relief valve take more labor but are still usually repairable, especially on tanks under 10 years old.
Best for: multiple related symptoms with no tank leak.
Full Replacement
When the tank itself is leaking, corroded, or the unit is past 8-12 years old with repeated failures, replacement is usually the smarter long-term investment.
Best for: aging tanks with a leak or several unrelated failures. See our Water Heater Installation and Tankless Water Heater Installation services.
Signs You Need Water Heater Repair
No Hot Water
A cold shower with no warning is the most obvious sign something has failed — often a thermocouple, heating element, or gas valve.
Rusty or Discolored Water
Brown, yellow, or rust-tinted hot water points to internal tank corrosion or a failing anode rod, especially in older units.
Popping, Rumbling, or Banging Sounds
Loud noises during heating cycles usually mean sediment has built up on the tank bottom, causing water to boil beneath it.
Water Pooling Around the Base
Moisture or standing water at the base of the tank can signal a fitting leak or, in worse cases, a cracked tank.
Pilot Light Won’t Stay Lit
A pilot that keeps going out is a classic sign of a failing thermocouple or a draft issue in the venting.
Inconsistent Water Temperature
Water that runs hot, then lukewarm, then cold again often points to a failing heating element or a sediment issue.

Common Water Heater Problems by Component
Our Water Heater Repair Process
If your water heater is actively leaking or you smell gas, treat it as an emergency: shut off the water and gas supply and call us right away. See our Emergency Plumbing and Emergency Leak Repair pages for same-day response.
When Repair No Longer Makes Sense
Not every failing water heater is worth repairing. As a rule of thumb, if your tank is more than 8 to 12 years old and you’re dealing with more than one issue at a time — say, a failing heating element and rust-colored water, or a pilot that won’t hold along with visible tank corrosion — replacement is usually the more cost-effective choice.
Repeated service calls on an aging unit add up quickly, and a tank nearing the end of its expected lifespan carries a real risk of a sudden failure that floods a garage or utility closet. During every repair visit, we’ll give you an honest read on your unit’s condition and expected remaining life, not just a quote for the part that’s broken.

If replacement makes more sense, we install both standard tank units and space-saving tankless systems — see our Water Heater Installation and Tankless Water Heater Installation pages for details, or our Gas Water Heater Installation page if you’re specifically considering a gas-fired replacement. Either way, the decision is yours, and we’ll never push a replacement you don’t need.
