Repairing a tank heater
Lukewarm water, a drip at a fitting or a burner that will not light may come down to a single part. Once the plumber has seen the unit, you hear whether repairing it or replacing it is the better choice.
A heater near the end of its life, a puddle by the tank or showers that run cold are good reasons to call. Describe the unit and what it is doing, and we match you with a local plumber.
Your estimate is free and personalized. The site also has tools for sizing a new unit and reading the age of the one you have.

A tank that has run its course can be swapped for a new one. Matching the unit to your household comes first, and the plumber helps you choose.
Going tankless changes the demands on the house. The unit heats water as it flows and needs its own gas or electrical capacity and venting, which is why the flow calculator is worth a try first.
Free up floor space by relocating a heater, or put a second heater near a bathroom that sits far from the first. The plumber plans what the new spot needs.
San Marcos issues a heater swap as a residential plumbing replacement permit, which is the City’s own label for this kind of job.
The Contractors State License Board lists water heaters under C-36, its Plumbing Contractor class. Gas and water lines from the owner’s side of the meter up to the structure sit in the same class.
Apart from small jobs the state exempts, a heater swap goes to a licensed contractor, and a job that needs a permit does not count among the small ones.
An earthquake can shake a water heater loose, which is why the state requires one to be supported and strapped.
San Marcos’s January low feeds the tankless flow calculator, which counts gallons per minute. Tank shoppers have a different tool, the water heater size calculator, and it asks for household size and busy-hour hot-water uses before returning a first-hour rating and tank size.
Serial numbers are printed on the label, and the serial number decoder converts one into a year of manufacture. How old the unit is feeds into whether repair or replacement is the better call.

Water pooling around the tank can be a leak finding job before it is a heater job, and supply lines due for replacement are repiping work. Call us about any other San Marcos plumbing need.
