My Hayward Super Pump 1hp is, like others here, running extremely hot (can't touch it) and is now also running loud. It is 11 years old. I am second owner and original pump was also replaced at the 11 yr mark. Do I need to replace the whole pump or just the motor? Also, do I need to stay at 1 HP? I do not have a main drain. Just the skimmer and 2 returns.

Also, should I order online?

Thanks.
