Water heater repair vs. replacement: how to decide

Repair usually makes sense when

The heater is under about eight years old and the problem is a single part:

• Pilot light or igniter will not stay lit
• Thermocouple or gas valve failure
• Heating element on an electric unit
• Thermostat or temperature and pressure relief valve
• A leaking fitting or supply line, not the tank itself

Replacement usually makes sense when

• The tank itself is leaking. There is no repair for a rusted-through tank.
• The unit is past ten years old and needs any repair over a couple hundred dollars
• Rust-colored hot water, which means the tank is corroding from the inside
• Rumbling or popping, which is scale buildup on the bottom of the tank
• It is the second repair in two years

Why Norwalk water matters

Southeast LA County water is hard. Minerals settle on the bottom of the tank and build a layer of scale that the burner has to heat through. That is the popping sound, and it is why heaters here often fail two or three years earlier than the label suggests. Flushing the tank once a year slows it down. It does not stop it.

What replacement involves

Most swaps are done the same day. Mickey brings the new unit, pulls the old one, connects water, gas, and venting to code, and hauls the old tank away. Water heater replacements in Norwalk generally need a city permit, which is handled as part of the job. Tankless units are an option when the gas line and venting support them; ask on the call.

Describe what the heater is doing and Mickey will usually tell you on the phone whether it is a repair or a replacement, and what each would cost. The estimate is free either way.
