Repairing a tank heater
A tank that gives no hot water, runs lukewarm or makes noise may need a part instead of a whole new heater. The plumber you hire says which it is.
Tank heaters that have stopped working, tanks that leak, tankless conversions and brand new installations all belong on this page. Call and tell us what the heater is doing, and we connect you with a local plumber.
Vista’s handout words the strap rule, the state plumbing code sets the permit line, and a state classification covers heater work.

A tank that gives no hot water, runs lukewarm or makes noise may need a part instead of a whole new heater. The plumber you hire says which it is.
When a tank has failed, a new one is set in its place with new connections. Tank size and fuel type are worth settling on the call.
Going tankless puts a compact unit on the wall that heats water only as it flows. The tankless flow calculator on this site helps you size one before you call.
A heater can go in a different spot or into a house with none, which takes new supply, drain and venting runs.
The state plumbing code is what asks for a permit when a water heater is installed, removed or replaced. Vista’s own handout on water heaters is about strapping. Emergency repairs on equipment follow the next working day permit rule explained on the emergency plumbing page.
For heater work, the state’s C-36 classification, from the Contractors State License Board, is the one that includes installing equipment to heat water.
California requires water heaters to be supported and strapped against movement in an earthquake. Vista’s Building Division handout names the strap as metal, not less than 22 gauge and not less than 3/4 inch wide.
To size a tank, run household size and busy-hour use through the water heater size calculator, which returns a first-hour rating and tank size. For a tankless unit, the tankless flow calculator weighs the showers and fixtures running together against Vista’s January low.
The serial number decoder reads a heater’s age from the brand and the serial number on its label. A heater’s age is worth knowing before you decide between a repair and a replacement.

If a water heater has been leaking and the water has soaked into a wall, leak finding is the page to read. Supply lines that feed the heater belong to repiping, and Vista plumbing of any other sort starts with a call to us.
