we have a very old AO smith pump at my parents house. Recently the circuit breaker has tripped shortly after the pool pump had gone on, I know because the timer was just at the beginning of the 6 hour cycle. I flipped the breaker and it started to run. My suspicion is the pump which is very old anyways may be dying etc. I could be wrong about the reason for the circuit breaker to trip.
Lets assume the pump is dying. I am pretty certain it is currently running as a 110 pump. The OLD piping coming in and going back is 1.5 inches and metal. The newer piping that got plumbed in is 2 inches. We run the pump 6 hours a day and it is running a zodiac g3 pool cleaner without issues.
Here is my question, should I replace with a 1.5hp or go with a 1.0hp pump ? I ask because some of the older stuff moves less water than newer less powerful / more efficient motors. I just need it to run the zodiac and I am happy. I can even run it longer etc.
Also doing a quick ebay search there are many inexpensive pumps, should I avoid and go with a name brand ?
