We're having trouble with water coming from the jets. The DE filter pressure is very high when the pump is turned on even with the filters being cleaned. When we tried to pour de powder down the skimmer after cleaning the filters there was no suction at the skimmer. We got a plumbing bladder and stuck down the skimmer hole to see if there was a clog but the water came out at the pump, as if no clog. We know water is coming out the filter because we removed the top of the valve and saw water flow to each pipe for the jets but no water is coming out the jets. We tried the bladder down each line (pool, spa, and fountain lines) and water only came flowing out of the fountain. We turned the pump on again to see if maybe the lines were cleared and there was pressure for a little bit when each side was open separately (pool and fountain are together spa is separate) but no flow when all lines open at the same time
