I'm a long time lurker but could use some input on a replacement pump for my pool. My existing pump is screaming like a banshee and also leaking from between the motor and pump body (even after replacing the seal), so I think it's time for it to go.
I'm curious about recommended replacements. I'm concerned about (i) keeping a good flow rate because I only have one return and one skimmer and (ii) whether a multi-speed pump would cause issues with my heater (e.g. not enough flow rate to keep it running).
I have a 22,000 gallon 36x18 concrete pool that was built in the 1970s.
It has one return in the center of the shallow end and one skimmer at the deep end. It had a main drain, but it was plugged. The whole system uses 1.5" PVC. The pipe run from the heater output to the return is probably about 40 feet. From the skimmer to the pump is probably only about 6 feet.
The other equipment is:
Filter - Hayward Sand Filter - S270T
Heater - Hayward H400FDN
Chlorination - Stenner Pump
The Existing Pump is a 1HP generic motor on what looks to be a Hayward Super Pump pump body.
I'm in NJ, so I only run the pool from memorial day to labor day. I tend to run the pump 8 hours a day (6am-2pm). I use a mechanical instamatic timer. I only run the heater for the weekends, so I'll turn the heater on Friday night and the heater usually brings the temp up about 1 degree an hour. I'd love to save some electrical utility expense, but I've read that the heater has a minimum flow switch, so I'm worried that a two speed or variable speed pump would not work for me.
Anyone have any suggestions? Let me know if there are any other details or info you need.
