How to Replace a Hayward Side-Mount Key Assembly and Spider Gasket on a Vari-Flow Valve!

In this video, we show you how to replace a Hayward 710 Side-Mount key assembly as well as the 5 spoke gasket, commonly referred to as a spider gasket. The key assembly is the top half of the vari-flow / multiport valve found on your sand filter (Hayward filter valve).

I love these videos. I'm not normally a DIY'er but Mark does such a great job explaining things that I feel courageous enough to try some of my own repairs!

Thanks again mark for all the posts, editing, and content

Thank you Mark for this video. You saved me a few hundred dollars.

I have seen some videos that use super glue to apply the spider gasket. I think that must have been the case with the one I removed. Took me forever! BTW - I ordered a replacement gasket from you today. Great videos! I wish you were closer to me (NJ).

Hey Mark, we are new to pool community and learning more every day. With that being said, your videos are great! The handle on our Hayward SelectaFlo Valve busted. We knew it was towards end of life when moved here, so we had purchased a back up valve assembly. When it broke, we felt it would be an easy fix to replace the entire key assembly. There doesn't appear to be any cracks and we did put lube on the o-ring. We are worried about tightening it down to tight and cracking something, but overall we have tightened it down firmly. Any suggenstions?

Thanks for the great videos. What is the difference between Hayward SP710XR50 and SP0710XR50 multiport valves? Thank you.

Is putting a glue a must below the spider gascket or nice to have?

Do you drain the filter or shut off external valves to prevent pool or hot-tub water from coming back up into housing once you 'pop the top'?

Morning! I have the 710 side mount and it’s leaking from the bottom of the handle at the top. I’m thinking it could be an o-ring on the shaft of the diverter. Would I need to bleed the pressure or drain the filter in the filter before removing the handle and key assembly or just leave it in the filter position and shut the pump off before removing the handle and diverter or key assembly. Thanks in advance!

Seemed simple when I ordered the parts and replacement gasket. But the removal of the old spider gasket is proving to be impossible. I don't know what type of adhesive they used but NASA needs to be using it! I've managed to remove the inner portion but the outer ring is not coming out no matter what I have tried. Any ideas?

[monimorrissey]

Does the gasket have to be glued down??

[thorsmith]

Some sites talk about adding a lubricant to the gasket and seal. Do you recommend that?

[drbennett]

I just replaced the mount key assembly, and it is still leaking. I didn't replace the spider gasket, but it seemed in good shape. Should I go ahead and replace the spider gasket anyway to see if that is the issue? IF I do that, and it still leaks, what might be the cause?

Hi Mark, my 6-way Hayward muiti value has its waste outlet and sight glass on the left side of the filter mount tube. These are on the right. What value would mine be?

[ray.a]

What if it's leaking from the top at the bottom of handle that's the problem I have .I don't know if I can replace a gasket under handle or do what you did and replace top part?

How do you change the o ring on a side mount multiport valve

[joslily]

How can I replace the two locknuts right underneath the assembly?

[leeroyjenkins]

Would one of those key assembly work on a sp7015g11m?
