I opened the pool to find bubbles on return. sealed up everything I could think of- finally no bubbles- had enough suction to vac through waste, but now I have no pressure.... waste line was working the other day when vac and backwashing, but now does nothing- no water comes out at all.. tried a bladder, you name it and still don't have enough suction for skimmer to keep top clear.. have a huge college graduation party and son Commissioned as 2nd LT- headed off to GA for 8 month and I have tons of people coming for a pool party.. how to I fix this quickly???
