We have finally to take the plunge get started on a pool build at the house. After visiting several builders in the area I believe we have decided on who to use. I'm trying now to understand just where I need to go with pump/filter decision. My goal is to build a fairly efficient pool as I think the long term savings will overweigh the cost of intial purchases. My builder uses Pentair products and is suggesting a D.E filter. They are suggesting the System 3 DE and indicate it would save $40-60/month on my electric bill over a sand filter since it will not run the amount of time each day. I've been reading spec sheets, forums and reviews till I can't see any more almost. I could really use some advice to make a educated decision on the pump/filter combo.
1) Is the System 3 a good choice or is there a better. ie Quad DE./Will it really save on the power bill to go DE.
2) With a DE system is a VS pump recommended or is that over kill with the reduced filter time. If I'm only running the pumps at night for 6-8 hours is there really any effective savings in the VS pump compared to it's initial price.
Will probably be installing a Easy Touch system with Salt system as well.
Any help would be really appreciated. This is a large undertaking to try and get all the information absobed.
