Had a horrible opening at the start of the year(memorial day crappy weather in Wi)... alot of the debri feel off my winter covers back in the pool.. shocked and have been running pump pretty much no stop... some how I got sand in the pool ... have been vacuuming out... I think my internal piping in the sand filter is broken... I bought new sand (current is about 2 years old) so tonight Im going to take it all apart and inspect.... put new sand in.... my question is once i have the new sand in ...and I start vacuuming the sand in the pool will it fill up my filter... I tried a sock in the skimmer basket.. but didn't work.. didn't allow alot of water back to the pump.. starved it of water... any thoughts.. I hope I explained it correctly.. thanks scott..
