We just recently purchased purchased our house and the pool pump is leaking already. Before we purchased it the motor on the pool pump was going out so the seller replaced it. I'm not sure if the motor they replaced it with was new or used but it looks fairly new. The new motor is kind of noisy, doesnt really bother me but i would rather buy a new pump than fix this one especially not knowing the history. It seems to be leaking around where the new motor is joined to the pump and started leaking a month into the new motor. Currently we have a hayward northstar 2hp pool pump and the pool is about 13000-15000 gallons. I'm considering a variable speed pool pump but don't know if its worth the additional cost. We pay .10 cents per kw and .075 cents if the usage is over 1000kw, which is not hard to do. Im considering the 2hp single speed Hayward SP2615X20 for about $450, the 2hp Hayward SP3200VSP TriStar for $775 or the hayward maxflo SP2302VSP for about $650. Is it worth the extra ~$300 to go with variable speed for me?
