I would like to buy a variable speed pump that is quiet and energy efficient, with a digital display/timer. When I go to the Pentair website they have several different ones to choose from but I don't know which one is right for my pool. I have a 18,000 gallon inground gunite pool. It is salt chlorinated, not heated, and there is no spa attached. The pump I have currently is hayward 3/4 hp. A neighbor with a pool told me they love their new Pentair brand, but I would also be open to a Hayward brand. Any advice on which is proper for me?

Just purchased a variable speed motor (10A max), and decided to completely re-wire from the house to the pool. Old switches and receptacles were rusty, etc and seemed like a good time to upgrade everything. Running 10-gauge wire out to pool inside pvc conduit the entire length. Would like to install a plug end on the pool motor instead of hard-wiring, so I can easily remove pump/motor assy for the winter here in CT. Using a US MOTORS/EMERSON ECOTECH EZ #EVSJ15-NS Variable Speed Motor wired for 230V. Motor only calls for 3-wire connection (L1-black, L2-red, and Ground-Green). However, when I look at 30A and 50A receptacles, appears latest code (after 1996) calls for 4-wire receptacles and plugs for 230V appliances. I have a 4-conductor 10g wiring running from main panel to the GFCI enclosure on the house. Should/can I run 3 wires out to pool (eliminating white wire), install a 3-prong receptacle, and run a 3-prong plug-in from the motor. Or, should I run 4 wires out to pool, install a 4-prong receptacle, use a 4-wire plug on the motor, but just not connect the white wire? Don't want to run 4th wire out too pool, if it's not going to be used, and at cost of copper wire (x 60 ft), seems like a waste, unless req'd by code. And. . . if required by code, why isn't a brand new VS motor setup for a 4-wire connection? I am obviously mounting everything in weatherproof boxes (was planning to use 30A or 50A weatherproof enclosures from GE designed for outdoor RV hookups). Hoping some electricians chime in and can lend some guidance. Trying to wire and pick up parts this weekend, so any comments today would be greatly appreciated. Thanks in advance for your assistance. -
I want to upgrade my Sta-Rite Max-E-Glas II pump to a more energy efficient variable speed pump. My pool is 19x23 13,500 gallon pool that is 5ft in the deepest section with no spa attached, and I want to make sure that I am not going to purchase a pump that is overkill my my size pool. I am averaging 28 kWh a day at an average cost of .22 and hour. I originally was interested in purchasing the Pentair Intelliflo VS pump, but then talked with a Hayward Rep at my local pool store was steering me toward the Hayward Max-Flo VS which is less horsepower and $$, and explains that it will save the same amount of money as the Pentair. Again, I have a small pool, and want to know if anyone has either of these cost effective variable speed pumps. IMG_1167.jpgIMG_1173.jpgIMG_1170.jpg
