I'm currently replacing a Hayward Northstar 1hp pump which has been nothing but trouble with air leaks via the lid gasket for the past 5 years (I've changed multiple gaskets, and they always seal for a few months, then leak). The motor is making a crazy noise, so I've decided to replace the pump.

I've done some research, and there seem to be three pumps that would be good replacements: Hayward TriStar VS (new this year), Pentair VS Intelliflo, and Jandy VS FloPro.

Do any one of the three offer any significant advantages over the others? They are all pretty similar in price - not including the suction block detection feature. Power savings seem similar, programs seem similar - my main concerns are longevity, best lid gasket on the market , and resistance to electrical surges. I do not use an automation system.

I did find an Intermatic surge suppressor which I believe can be used for any of them. To me, the Intelliflo seems best for longevity, but the Jandy has some nice design features.

Would really appreciate any thoughts and findings from others who've done research or are familiar with any of these pumps - especially on the Jandy FloPro.

My pool is 20x40, 27.5k gallons, 400k btu starite heater, starite SM150 cartridge filter (450 SQ ft), external chlorinator, vinyl liner, poly walls, 2 skimmers, 1 main drain, 1 skimmer is a 1 1/2" home run to pump, 1 skimmer+ main drain 1 1/2" line back to the pump, 2" pipe joining the lines into the pump. Return is 2" line which splits into two 1 1/2" lines with each splitting to two returns into the pool wall, and walkin steps. Pool is about 35ft from the pump.
