Is there a multiport valve for the Hayward filter model W3DE6020?

A  Answered on 6/20/2021 by InyoPools Product Specialist Patrick P.

Currently all of the multiport valves for the W3DE6020, this is an industry wide shortage with all retailers, however, this slide valve does work on the W3DE6020. The slide valve is in stock but selling quickly. I personally like the slide valve just as much as the multiport valve.

    I have followed the instructions to backwash my pool but the valve will not extend up and it will not turn counter clockwise. I don’t want to force it to turn for fear it might break. Any suggestion? Are there any backwashing videos on how it should work? Thanks

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

I already have a slide valve which is brand 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).

A  Answered on 10/20/2014 by InyoPools Product Specialist Patrick P.

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

I need parts for my filter valve. When I look at the filter parts breakdown, it gives me different choices. How do I know which one is the one I need?

A  Answered on 1/31/2012 by InyoPools Product Specialist Patrick P.

In order to locate the correct parts we will need to know the model number of the filter valve. Two identical filters can have two different valves. Typically the valve model will be located on the label of the valve. If there is no model number on the valve, you can try to see if there are any part numbers on the valve itself. Once you've located you valve model you can check out our >Filter Valve Parts.
