Just found this forum and I gonna through out a question to see if I screwed up.
My 30+ year old Hayward 1607x10 pump just died and I have a replacement on order (it hasn't shipped yet). I was thinking my old pump was 1-1/2 HP so when I was looking at my options I decided to purchase an SP2615x20 2 HP thinking I'll give myself more ooomph and things will work better. I was concerned about plumbing but just kinda pulled the trigger before I did all my research.
After digging into the specs I realized that my old 1 HP is only 1-1/2" piping (I also realized that everything up to 1-1/2 hp looks to be 1-1/2").
My question, I guess, is three parts.
1) I realize the 2 HP is probably overkill, but I've always wanted to add a cleaner. Is the 2 HP too much of an overkill? Would I be ok with a 1-1/2 HP. My pool is 16'x32'. According to the company who installed it, is 18,000 GALS.
2) More importantly, will the 1-1/2" piping be starving it? I'm thinking I can adapt it up, but will it shorten the life of the pump.
3) Or will the pressure be too much on the filter. I have a Hayward EC-65.
I appreciate any feedback.
btw.. thought I'd edit this after I posted. I move my pump a few years ago to a shed about 20' from the pool and sits up about 3' from the water level. I just always felt like the pump worked a little hard since I moved it. I also run it on 2 - 6 hour shifts. A ran it less right after we moved in but it wasn't keeping it clean.
