PSC Ep. 70: Why is DE powder coming through my skimmer & main drain?

  1. I get DE leaking back through my skimmers and main suction whenever I turn on the water feature valve, after the pump is off. When switched to jets only (both utilize the same jandy valve) I have no DE leak. What could be the culprit? I have checked everything suction side and even pulled my filter grid and checked the standpipe and grids. No leak from the pressure relief valve and I had my backwash valve replaced. 35,000 gallon inground pool with FNS plus 60 and pentair 2 hp whisperflo.

    1. The water feature valve you are turning, or the pipe leading up to that valve has an air leak, causing the pump to lose prime once it is turned off. Or, if your water feature is above the pump when the pump turns off that water flushes backward through the system bringing the DE through the filter, pump and into the pool.
