I have in-ground pool, and the pump is about 35 feet away and 1 foot higher than the skimmer line. My power is 240V. This is my 4th pump overall, and it seems to be better than all previous ones I had before. I've been running it on a timer 16 hours a day for just over a month now.Now, the bad 2 things about this one:1. Like someone has already described in his review here, the electric connectors on a 2-speed switch are designed for a flexible smaller-gauge wires with a slide-on female disconnects that need to be purchased separately. While the pump manual calls for a 14-gauge wires, which are 1.6mm solid copper gauge that I have, the pump connectors are not designed for a solid copper 14 gauge that need to bolted on like the Ground wire on this pump. So I had to go to Home Depot and buy what is called "Disconnect F" gauge 16-14 Female Disconnects and crimp them to my solid copper wires for my 240V power. After that you hope that the crimps will stay on and won't get loose with all the vibration of a working pump over the years..2. On low speed- bubbles in the output jet, telling me the pump is "suffocating" as there's not enough water flow on the intake. I have a salt generator cell, so bubbles are not allowed because they can damage the cell. For those that don't have a salt water pool, that probably won't matter. I wish they made the Low speed a little more powerful, not 2.2 Amps but maybe 10-20% more. I can run it in winter time when the salt cell is off, but for hot summer days in Texas, it's a Max speed 16 hours a day.The good: on Max speed, it sucks like a champ, also consuming about half the Amps than my previous pump that couldn't suck as good as this one. Better than any other pumps I ever had. It primes quickly, while the in-ground pool's skimmer is about 1 foot from the pump's suction plane, and about 35 feet away. I can also vacuum the pool without suffocating the pump, no matter how long it takes, which all previous pumps of similar horsepower couldn'
