    Dirt/Sand in Hot water line
    House is 7 years old, built on slab, pex in slab copper above.
    Water supply is City Well water unfiltered.A whole house Big Blue filter was installed to remove high levels of Manganese and Iron after moving in and observing brown water in the bath tubs. This cleared up the colored water problem.

    About 3 years ago we started to see dirt/grit when we turned on the hot water for the bath tub, ONLY noticed in the hot water. After many visits by the plumber we had the hot water tank, expansion tank and recirc pump replaced. THE PROBLEM STILL EXISTS!! More than 1 local plumber is stumped as to the cause. There does not appear to be any leaks anywhere in the system, the water meter was observed with nothing turned on.

    Does anyone have any ideas as what the cause may be? Again only hot water and all new hardware except for behind the wall plumbing.

    Thank You
    Bob

    Can you post a link to the filter manual? Does the filter backflush? Any running out of hot water issues or varying hot water temps throughout the house?

    Do you flush your heater out on a regular basis? If not let me show you how.



    For long life and fewer troubles you should keep your heater clear of mineral build-up by FLUSHING NOT DRAINING on a regular schedule. Attach a hose to the boiler drain at the bottom of the tank. With the pressure on, open the boiler drain and let it run until the water runs clear. You will see a spurt of red,(rust) followed by white or yellow grains,(lime or calcium carbonate). This shouldn't take more then a few minutes. Do this monthly to keep it clear. Now flush out your hot water lines on ALL fixtures that are affected . Now pull each aerator and clean the screens. Be sure you put them back together the same way you took them out. Don't forget to flush it out every month. Your heater will thank you for it. Hope this helps and thank you for rating my answer, Tom
