I've been lurking on this forum for a long time. I've managed to fix most of my problems by searching Pool School and the forums. I think this is my first post.
I'd like to replace my old and weary Pentair IG pool pump, it has a 1 HP, 3450RPM single speed Emerson motor. It has a leak at the pressure side connection and when trying to fix it I noticed that the threads were cross threaded. This pump is probably 20 years old and I only know it's a pentair because my local pool shop identified it from a picture. I've owned this pump/pool for the last 4 years and despite fixing annual leaks and being loud it's worked pretty well. It's given me pretty good flow from my returns with and without my solar heating system on.
Now, I think that the pump has other problems. I can't get my pressure below 32 PSI even when I'm running in recirculate. I've already checked all my suction side connections and pump basket for leaks and lubed/replaced my O-rings, in my intake union ball valves. I'm pretty sure the problem is the pump itself.
My plan is to replace the pump with another single speed 1 HP pump and replace my 1 1/2" union valves ( the handle is cracked on one) for the skimmer and drain. My plumbing is all 1 1/2", the skimmer is about 20' from the pump, drain is about 50' away, and the pump is only about 6" above my water level. Additional details on my pool is in my signature.
I'd like a pump that has easily obtainable replacement parts and has a reputation for being reliable and easy to service.
I've been thinking of the Hayward Superpump max rated single speed, which I can get on Amazon for $339 including free shipping.
I'm not sure how to figure out whether this would work or not, and would appreciate some feedback from someone who better understands how to size a pump. Would this do the job?
-Thanks in advance for your help
