Hello, I have an inground pool with an associated spa. I am wondering if anyone has ever experienced the filter pressure tripling when the spa is isolated?
This is a new issue so I thought I needed to backwash my system. After doing so, when I open all valves (pool and spa) or isolate the pool the filter pressure is in the clean range. However if I close all the pool valves and send all the water to the spa the filter pressure triples and the gauge goes from reading 10 PSIs to 30 PSIs. That is well pass the clean filter indicator.
My filter type is DE. Pool type is chlorine.
Any ideas, advice or help is appreciated. Thanks
