    FHP Plugged Coax

    I have a customer that has a 3T FHP Open loop discharging into a creek. The water quality is not good. However, their FHP has a plugged coax 100%. I've tried flushing from the leaving to the entering and vise versa. I have also tried blowing it out with nitrogen. I could try using chemical to flush however, I don't have much faith that it will work since I'm not getting any water out at all or nitrogen. Any ideas other than replacing the coax and or unit?

    I ran open loop for awhile until it clogged. Then I cleaned it out with Muriatic acid and switched to closed loop. Did you try Muriatic acid?

    Get your post count up and apply for pro memebership and there are some good 'solutions'.

    FWIW, the HCl mentioned is excellent for Ca and Mg deposits......
