Pump set up for an inground pool install in a high water table

[lWINK1479]

my husband is installing our pool he is a mason not a pool guy. we are do it yourselfers from nj. it is a 14 x 28 grecian 6 foot deep. we hit water as we were excaveting for the main drains. we have removed about 15" of dirt in the bottom and added stone and a temporary pump.

1. do we need a perminant pump to remove ground water to keep the liner in place (we will be appling a portland sand bottom)after construction?

2. Can I just use my pool pump to pump this water if a create a separate valve?

3. do we need a hydrostatic relief valve for the bottom?

any information would be greatly appreciated. thank you

You can't count on the pool pump being able to maintain a water lift of 4+ feet.

The only way I've heard of construction being done under those circumstances is with EITHER a sump pump left under the pool, OR a line with a foot valve and gravel well, to be used with a construction diaphragm pump (expensive!)
