Pete's PlumbingNo hot water: what to check first
Before you call, check the breaker on an electric heater or the pilot on a gas one, and look for water around the tank. If the tank is leaking, shut the cold supply and call.

A few quick checks can save you a visit, or help us bring the right part.
Electric water heater
- Check the breaker for the water heater at the panel. If it tripped, reset it once. If it trips again, leave it off and call.
- Some heaters have a red reset button behind a panel on the side. Only press it with the power off at the breaker.
Gas water heater
- Look through the small window at the bottom for the pilot flame.
- If it's out, follow the relighting instructions on the label on the tank.
- If it won't stay lit, or you smell gas, stop and call.
