Hi guys this is whats going on. I have a 10000 gallon in ground vinyl liner pool about 6 years old, 1 1/2 hp pump, D.E. filter ,gas heater A new pump was installed this march before we opened the pool,along with a new mulitport gasket.Last thursday the pool co. opened the pool but it would not prime.After an hour of trying different things they left but the owner of the company came up later that eve. determined that the gasket around the filter basket needed to be replaced as well as the pressure switch for the heater..Well they finally got back on Monday,needless to say still nothing circulating. This what i did this morning, i turned off the pump,waited five minutes, turned it back on and everything was circulating, waterfall working, then as i watched, the water level in the skimmer basket slowly dropped and nothing was circulating, but the pressure was reading close to 30 lbs.So i have a new pump thats not doing anything but has a high pressure reading.Its 7.24 here in central jersey and the pool co. opens at 9.Sorry for the long post but any help would be appreciated.
