Shutdown Instructions

If you have a leaking water heater, follow the instructions below or watch our video to turn off your leaking water heater, you can also call (619) 222-3814 and one of our water heater experts will walk you through turning off your water heater.


1. TURN OFF THE Gas or Electricity:Water Heater Pilot San Diego

Gas: Twist the dial on the top of the thermostat from the “on” to the “off” position. This will turn off the gas at the water heater. If you ever smell gas – exit the home and contact the gas company immediately.

Electric: Find your breaker box and flip the breaker for your water heater or if your water heater has a disconnect switch close to the water heater simply turn off the switch to turn off power to the water heater.



Find the cold side water pipe connected to the water heater and follow the water pipe back to the source or the wall – you should see a water shut off valve.

Gate Valve: If you have an old style turn faucet handle – Twist the handle clockwise until it stops. This should turn of the water.

Ball Valve: If you have a newer lever style ball valve pull or push the handle a quarter turn – this should turn off the water.

Water Heater Drain San Diego


Drain the water heater if necessary to avoid any damage by connecting a garden hose to the bottom drain valve on the water heater. Run the other end of the hose to a lower location where hot or rusty water will not cause damage (hot water can damage grass and plants). Open the hot side faucet in the sink closest to the water heater – this will release the vacuum seal and let the water drain out of the water heater. Allow 10-30 minutes for the water heater to drain.


Water Heater Too Noisy

Is your water heater too noisy and starting to be a nuisance? Water heaters will make noises from time to time and that doesn’t mean that something is wrong with it. However, some noises are indications of problems and it can be difficult for the average person to decide which is which. That’s where we come in. You can always call one of our water heater experts at (619) 222-3814 and they can help you decide if it’s something that needs to be fixed or not. One of the common noises that you might hear is a “rumbling” noise. This is the sound of heated water escaping from sediment that has built up on the bottom of the water heater. This is not necessarily dangerous, but could lead to problems down the road and could definitely lead to a less-efficient water heater.

 As sediment builds up, it causes more heat to escape through the vent and that means there is less heat being used for the water. This can also lead to overheating the bottom of the tank, which could shorten its life and ultimately cause the failure of the water heater. Sediment deposits are even worse in areas with “bad” water, though regularly flushing the water heater can help extend its life and save on energy costs. If the sediment is not removed, it can harden and become like coral in the ocean. If this happens, there is no removing it from residential models. Again, flushing the water heater regularly can help and that should fix the problem of the rumbling noise. If not, it may be time to replace it.

Another common report is that of a high-pitched noise. This can be the result of a high incoming water pressure and, if left unchecked, could become a problem and should be diagnosed and repaired as soon as possible. Water heaters come with a temperature/pressure relief safety valve, which is designed to open and release water when the pressure or temperature gets too high in the tank. If this valve fails, then the water heater could become over-pressurized. Long term excessive pressure in the water heater or plumbing system could lead to cracks, leaks or even, in rare instances, a burst water heater.

Of course, you can always call one of our water heater experts at (619) 222-3814 and they will be glad to help answer any questions you might have or help diagnose any issues you are having with your water heater. And if that doesn’t solve your problem, we can always send one of our trained technicians and they can make a diagnosis on-site and even take care of the problem too. 

How Much Will It Cost?

The amount it will cost to have your water heater installed can vary and depends on a couple of factors. The most important will be the size and type of water heater you are having installed. Other factors that could cause the cost to rise include any plumbing upgrades or code requirements that may be necessary to properly install your unit. Nowadays, most cities require a permit for a water heater installation and that means we have to follow specific guidelines when performing the installation.
