I have a customer that has alot of sediment in their water and wants us to flush out their TR120 Phase III hot water maker. Has anyone ever done this before if so how did you do it.

    Tough to do....

    As you are probably aware, that is a tank within a tank design, and there is no easy way of getting to the bottom of the inner tank. The manufacturer shows how to set up a drain (siphon) on the cold water inlet to the tank, but what they don't tell you is that there is a small hole drilled in the cold water inlet dip tube to act as a siphon break, which pretty much defeats the idea of simply draining the tank...

    What I have done in the past is to use an automatic washer hose, with one end cut off, slipped inside of the hot water outlet tapping to do the siphoning. However, unless we are talking TDS in suspension, you will not be able to siphon chunks of any size through the hose.

    It is definately an achiles heel on that particular design.

    If the accumulation is calcium based lime scale, the use of a magnetic water conditioner MAY soften up the scale and allow it to be flushed out during regular usage.

    Filtration and avoidance is probably the best practice.

    a suggestion

    How about running a flexible tube down the hot side all the way to the bottom and connecting to as high a pressure outlet as you can get. On the cold side, open it up and attach a drain. That flex hose in the hot side should whip around pretty good dislodging sediment and it should eventually find its way out the cold side. Seems to me it would work.

    a Muck Vac

    is what you need. Ask Larry W here about the device.

    OK

    Muck Vac is a water based vacuum cleaner for tanks. It uses a positive displacement pump and (via a wand that reaches to the bottom of the tank) sucks up water and sediment. This goes through a filter bag, to the pump and the water goes back into the tank being cleaned. One moves the wand around to pick up sediment. The concept is simple enough though there are details. I've stopped making them, having finally understood I have limited energy and time, but would be happy to give pointers on making your own.

    Yours, Larry
