I'm going from a Hayward SP to Calimar VS pump and I see in the specs that there is a .2" difference in the center line of the hayward vs the Calimar. Am I looking at replumbing the whole inlet or is it possible to make it work with the existing plumbing? I've currently got 1.5" pipes so I'll need to use the appropriate unions as well. Thanks!
Hayward Superpump to Calimar install
- Thread starter ckh1980

I replaced a Hayward 2hp super pump ll with the Calimar 3hpVS using 2-11.25 elbows ( available online) and short connecting stubs with Hi temp Unions my plumbing was existing 2". Hope this helps you. All planning credit on my project belongs to 1poolman1 and his guidance.
I appreciate that. It's hard to tell from your pic, but are the elbows for elevation change or are they lateral? Also there's probably no sense in trying to replumb the little bit of 1.5" pump a have at the pad to 2" right?
elevation, also keep in mind when using the elbows the pump position will change it orientation (left or right) both in and out plumbing will be required.
my super pump ll was at 8-3/16"
Calimar is 9.126"
1 1/2 " schedule 40- 11.25 elbows are also available on line I don't see a reason to change.
thanks. before I order, I'm guessing the easiest thing to do is to get the 2" unions and glue in a reducer to 1.5"?
yes and unions were available on the Calimar site when I purchased my pump.

Here's one option. If your valve is a 2"/2.5" diverter, use a 2.5" fitting on the outside of the socket and reduce it to 2". See the connection on the left below.

The other option is to replace the valve or use a pipe reamer to clear out the existing socket.
Cost a lota provides two great options. But, Do you have any more room to move the pump back at all (your photo doesn't show the entire pad.) Maybe provide another photo.
you'll need to put that 1-1/2 reducer in play also.

The diverter valves are designed to work with two different size pipes. If your valve is a 1.5"/ 2" you would use a 2-in fitting and reduce to 1.5".
I've got about another foot of room behind it. The piping is 1.5 wouldnt the valve also be the same ID? I don't understand the 2"-2.5" reference earlier. Here Are some better pics. Yes I know the connector is missing for the electrical. It is being addressed
I might try the reamer first. I'll have to go pick one up from Lowe'sAttachments

I didn't realize your plumbing was 1.5 in. See my last post.
