Replacing a motor on a pump, and getting the correct size for your pool?

[mitchryan912]

But if you are going to the trouble of replacing a motor, I would get a two speed. Assuming you have a 48Y square flange motor, then you could use a UQS1102R motor but you will need to buy a 3/4 HP full rated impeller for the pump.

Would this be it? http://www.amazon.com/Smith-SQS1102R...ao+smith+1102R

It's a 1/.166 HP 2 speed motor. Since the full speed of 1 HP is the same as the impeller I have, would I be able to keep that the same?

That is impossible. You filter gauge is broken.

Yep, I noted where it is when there's no pressure, and subtracted that from what it reads when there is full pressure (about 25 psi.) Since the system is down, I'll take the time to replace that.

No need to. A pool can get by with as little as 2 hours of run time (see study).

If I were to go with a single speed motor like I linked above, could I install a timer inline with the motor and still see energy savings?
