Thread: Hot Water

  1. #1

    Hot Water

    Reduced hot water pressure all faucets. Have hot water, screens clean new relief valve.
    Any suggestions where to look for obstruction. Cold water great.
    Thanks

    Is the pressure the same at the faucet nearest the hot water tank as it is at the furthest away?

    Some marine hot water heaters have a mixing valve, which might cause this problem. A call to the manufacturer of the heater might help.

    All faucets have same pressure regardless of location relative to hot
    water tank. no mixing valves involved.

    You might try back flushing the hot water heater in case sediment has blocked the exit of the tank.

    I'd agree with Seven for a couple of reasons. I had this issue last summer, and while Pau Hana has a residential-style water heater that has only been installed for 3 years, I had to flush the tank last summer. I also had this issue in my dirt home in NC - that water heater was not downstream from a sediment filter, and I had to flush it annually. With my current setup, I have a sediment filter before the boat water system, for tank and dock water, and I think that's contributing to better quality and reduced maintenance on the water heater.

    Agree with others, flush the tank, you might be amazed (or disgusted lol). Seems like calcium and other salts/minerals just precipitate out inside the tanks.

    Be sure to flip the hot water heater breaker off before draining!! No quicker way to fry a heating element.
