New multi port valve?

[ethany]

Replacing my multi port valve and laterals......sand also for that matter. I was getting sand in pool but that's n my question.

My question is my new multi port valve came in and it needs 1 1/2" pipe. My old one is 2" pipe. Is that a problem? Can I just buy a fitting to go 1 1/2" to 2" without any issues?

Most multiports are designed to allow the fitting of 2 sizes. They either slip inside 2" or outside 1.5" or slip inside 2.5" or outside 2"... etc. If you could link the specific multiport that you purchased, that would help.

This is the new one

Hayward SP0714T Vari-Flo Control 1 1/2in. FIP Valve Top Mount In Line Sight Glass, Black

This MPV is designed to use 1.5" threaded fittings for attachment. What you'll need to use to connect existing 2" PVC to the multiport is a 2" to 1.5" threaded adapter. Probably 3 of them for each of the lines, unless you do a 1.5" waste line, then just a 1.5" x 1.5" threaded adapter for that.

You should be able to find one like this at a hardware store, Home Depot, Lowes... etc. http://www.pvcfittingsonline.com/436-213-1-1-2-x-2-schedule-40-pvc-reducing-male-adapter.html

Ok thanks.... It was my fault I should have told the online salesperson it was for a 2 " hook up. Extra $30 for stick of 2" n 1 1/2" pipe, glue n fittings. Oh well

no big deal..get the 1 1/2" to 2 inch pvc adaptor, and you'll be good to go. not a big deal at all.

Well it's done..... Almost. I hate after everything is glued together used Teflon tape in threads and all. The male adaptor threads into multi port is leaking. Not sure what to do. Even one of the unions is leaking.

Problem is Taking it apart. Spinning the pipe will be a problem even if I disconnect it at the Union. I hate plumbing

 

[flyweed]

then you probably didn't use enough wraps of teflon tape on the male threads...it should screw in snuggly..and DON'T put tape on the first 2-3 threads. if a solvent weld union is leaking, you'll have to redo it..just take your time, use the primer correctly and the cement and you should be good.

If the union is leaking make sure the o-ring is seated correctly and that you do not over-tighten it. Silicon pool lube on the o-ring helps to get a good seal as well. 3 rounds of teflon tape should do it, also be sure you do not over-tighten when putting it together.
