So we just acquired our in-laws 18' above ground round pool and this thing has been a nightmare. Most recent is that apon plugging in the pump the breaker trips. We've eliminated other issues with the electric and figure it's got to be the pump.

So, we have a Proline PE71-II-H pump with a Hayward DE filter EC40CPAKS

The pump, we knew maybe had a year or two left but my father in law tried to prolong it so we've been looking at the possibility of just buying a new pump.

So questions:

Are there pumps that are compatible with the Hayward?
Does it need to be compatible?
Can I buy just the pump or would I have to buy the whole set up?

It's a 1.5HP pump a believe.

I'm not trying to break the bank as my wife already has plans in 5-7 years of getting a bigger pool.

Whatcha think1?!
