I have a very old Hayward Max Flow 1HP pump (115v) that is starting to make a high pitch rattling noise. Separately I am having an electrician come out to fix a problem with the wiring to the pump, so I thought now may be the best time to replace it instead of troubleshooting the bearings/motor. My filter is a System3 DE filter that has a max flow rate of 74 GPM.
It looks like I can get a new Hayward pump to match my current one, but I wanted to get opinions on what to look for in a new pump. The current pump runs 24/7 but I am having a timer installed so I can knock down the run time to about 12 hr/day. Any suggestions?
