Hayward pool sand Filter SP714T Valve leaking?

I was a little late taking this valve in last fall. I may have been out in freezing temps a couple of nights. Just hooked everything up and water is dribbling out the backwash hose....

could this be taken apart and repaired? I'm going to search for any kind of " repair kit " or could I just cap off the backwash line until I need to use it?

I see a replacement online for $109 as a last resort..

TIA

Are those the ones with the spider gasket? If so it sounds like it maybe leaking. The one on mine is easy to replace but I'm not sure about yours. On mine I take the screws off just below the handle to expose the gasket. You might want to ask your pool material supplier.

Mine was backwashing into my hot tub. But the gasket slipped back into place on it's own. You might be able to get away with lubing and reseating the gasket but not knowing your valve I'm not sure.

This has 6 screws holding on a cover just below the handle you turn for backwash, etc... What are the chances there are user replaceable parts in there? Sounds like it might be worth taking apart for a look? Maybe a clean and reassemble will do it?

I'll bring it to the local shop and ask.

Yes. I checked mine it's a 710. Pretty much the same thing. I've never taken it apart but they assured me it's real simple. If you take the 6 screws off the valve selector section it comes out. There is a spider gasket right underneath. If you have the option to take the valve to your pool supply store just take it in. But like I said mine slipped back into place on it's own. My pool is in-ground and the parts are all glued into place so I can't take my valve in to be worked on.

These are the spider gaskets:

You can see how if one of the spokes slips out it can leak into the wrong valve. Mine was leaking backwash into the pool return. Not a good thing.

The spider gaskets tend to swell up and leak. Very simple replacement, just remove all the screws/nuts and pop a new one in. Do not lubricate it with anything. The secret to longer life if to choose one direction and always turn the valve handle in that direction, don't go clockwise one time then counter CW the next time.

You're right about the lubing. But, apparently it's supposed to be glued.

The Hayward site backs this up.
