I am a new member and have spent the past few days reading all I can on this site. I have a couple of questions though that I need help with. I have an concrete IG pool that is 12k gal. with no water features, no spa. 2 main drains 23' and 25' from pump, 1 skimmer 30' from pump. There are 3 returns about 20' and 30' on side of pool closet to equipment and one on far side about 40'. The motor is Jacuzzi (A O Smith) 1hp EE, 1.25 SF. Pump is Jacuzzi magnum plus and a Jacuzzi Sher 80 filter. There is a electric heater that I have never used as I don't own stock in Florida power and light. I use a barracuda G4 out of the skimmer, no dedicated line. Timer is intermatic T10004RT3. All plumbing is 2" except at outlet of filter, which is 1 1/2" male thread that goes immediately to 2". I believe the pool was built in 2004.
The motor quit and I need to replace it. The lid on the pump basket has already broken, and the pool store had a used one he gave me, other than that it seems to be fine. After reading for hours on this site, I believe the answers I am looking for are to go to a 2 speed pump, and that the filter is too small for this application. I would sometime in the future add a SWG and maybe solar, but not right now. The pad has 230v, and everything is easy to get to. I fix houses and cars, so electrical and plumbing are easy for me. I believe I can use a 3/4 hp motor for this application, however the superflo and super pump have 1 1/2 connections, while the whisperflo has 2". The whisperflo is about $200 more and it seems to be more efficient and has more flow, and looking to the future, this may be a good thing. I know at some point I will have to replace the filter as no parts are available, but I would like to put it off for a while if possible.
I am asking for expert advice on where to go from here quickly as I have a dead motor. Thank you in advance for your responses.
