Repairing a tank heater
No heat, a drip at a fitting or a rumble inside the tank does not always mean the whole heater is finished. The provider checks the unit and says whether a part will do.
Cold showers, a puddle beside the tank or a heater that has simply worn out all lead to one call. Tell us about the unit you have and we link you with a local provider for a repair, a swap or a fresh installation.
The page covers tank and tankless heaters alike, and the calculators here help with size before you phone.

No heat, a drip at a fitting or a rumble inside the tank does not always mean the whole heater is finished. The provider checks the unit and says whether a part will do.
A tank that has failed comes out and a new one takes its place. Before that, the size calculator gives you a first-hour rating to measure the new tank against.
Tankless units have no storage tank and heat water the moment it flows. Sizing comes down to flow and incoming water temperature, and the tankless flow calculator handles both.
A second heater, or one set up in a new spot, goes beyond a straight swap. The City’s heater permit entries are for like-for-like swaps in the same location, so mention a move or an addition when you call.
On Oceanside’s permit list a heater swap is Residential Water Heater Replacement, and a tankless one has its own entry, both for like for like in the same location. Contractors apply for these through the City’s eTRAKiT system.
Providers quoting heater work should be asked about the C-36 plumbing contractor class, which in California takes in installing any equipment that heats water.
California requires a water heater to be supported and strapped so it stays put in an earthquake. On a replacement, ask how the new unit will be strapped.
Sizing is easier with numbers in hand. Count the people in your home and the hot-water uses that overlap in your busiest hour for the water heater size calculator, or the fixtures that run together for the tankless flow calculator, which also uses Oceanside’s incoming water temperature.
Look for the data plate on your heater. Its serial number carries the year the tank was made, and the serial number decoder reads it once you pick the brand and enter the number. Knowing the age helps when the choice is between a repair and a new unit.

Trouble with supply lines near the heater is a matter for leak finding or repiping, and any other job starts from the homepage.
