I am having issue with water circulation. I have sand filtration system (triton II) and Hayward pump system. The pressure was getting high so I performed routine backwash like usual. This time, when I put it back to filtering, pressure is still high and I also lost flow from both inlet (skimmer and vacuum) and outlet. I can't feel any suction on inlet and I do not see anything coming out of the outlet. I can still perform backwash just fine which I think it tells me that the pump is working. I checked all surfaced plumbing and did not notice any leak.
What do you guys think?
Thanks in advance
