Hi — so this is our first full season with an after winterized above ground pool. Everything was running fine and then I let the skimmer basket off the pool fill with pine needles for a number of hours before I realized what was happening. Now, there is little to no pressure. I replaced the gauge but that didn’t help. No one can come out to look at it today although I did troubleshoot with someone over the phone. We have opened the pump basket and that is all clean (only filling about halfway). Have recirculated and backwashed and filtered to waste. Still little to no pressure. Help!!!! Please!!!!
