Water Heaters · Robert's Field Notes

Should I repair or replace my water heater?

I don't make the repair-or-replace call from age alone. The leak location and overall condition usually tell me more.

My short answer

Should I repair or replace my water heater?

I don't make this call from the age of the heater alone. I look at what failed, where any water is coming from, the condition of the tank and whether the heater is still keeping up with the home. Some problems are good repair candidates. A leaking tank usually changes the conversation.

When might a repair make sense?

A heating element, thermostat, valve or another serviceable part may be worth repairing when the rest of the heater is in decent shape. I also look at whether this is the first real problem or one of several repairs that have started stacking up.

The goal isn't to keep an old heater alive at any cost. It's to spend money where it makes sense and get dependable hot water back in the house.

When does replacement move higher on the list?

Water coming through the tank body, advanced corrosion, repeated failures or a heater that no longer meets normal demand can all point toward replacement. I want to confirm the source because water around a heater can also come from a connection or valve above it.

Before I come out, a photo of the whole heater, the area where you see water and the model label can help. I still need to inspect it, but those details give me a better starting point.
