Good afternoon all,
15-year-old Hayward SP4010X15NS Pump and motor assemble died and it had a 1.5 HP NorthStar motor. It pushed my water through filter, up to my solar water thinning/heating panels on roof and punished water through my two shooters and we added a fountain. When using the solar water heater, the pressure was not great. I replaced the pump with a Hayward W3SP2303VSP with a 1.65HP Variable Speed. I have this unit set to run on Speed 4 at the max 3450 RPM. When I’m in recirculating only I get minimal pressure to just my two shooters. They are piped into my concrete apron and are about a 3/8” opening and I have individual valve control on each shooter and the fountain so 3 shut off valves. I have 32000 gallons and my calculation says I should have a pump with does about 65-70 GPM and this unit does 125 GPM but I cannot get the pressure like my dead one speed smaller 1.5 HP motor pushed. Hayward DE Filter as well. My solar system is no longer in service we had new roof put on 2 weeks ago and it was trashed due to brittle of 15 years in the sun.
My issue is:
Did I purchase the new pump in the wrong size?
Did I miss a configuration on the pump to get the most pressure out this unit?
Since I have my new pump mounted and running (about 25 hours so far) cannot be returned and I have a possible plan. I can rework my pluming and add a booster pump for just the two shooters and one fountain without too much trouble or cost if i cannot or decide to not sell the new slightly used one.
My other option if I purchased the wrong size pump I may consider selling used slightly used and then purchase the correct unit. I’m looking for some guidance or suggestions. This group has saved me in the past. I’m not an experienced pool person but you folks really make me feel like I can pretend to be with your knowledge. I can do the work just lack the knowledge as to the best method. I also called Hayward and they were not willing to help a DIY and pointed to the Leslie store I purchased from, and they don’t answer the phone so not happy with their service. That leaves me to post here.
Thank you.
