I already have a slide valve which is brand new.....now i just need the fixture since I screwed up and it is leaking. Do you sell just the fixture? (The "frame" which the slide valve fits into).

Hi there - if you are needing the body of the valve which the slide valve piston assembly goes into then unfortunately this is not sold as an individual part. The least expensive option would be to purchase the complete valve assembly. Here is a listing of  the individual Parts available for the Hayward Slide Valve

What type of solvent is used to join slide valve to pvc pipe?

A  Answered on 4/17/2018 by InyoPools Product Specialist Lennox H.

Hi. We do not sell the solvent that you will need. You can use a CPVC solvent cement on PVC piping. However, we recommend that the correct Weld-On primer and PVC solvent cement for the particular application should be used
