Hey Ben, I have the SP715XR50 which looks very similar to this one.

Are there any rebuild instructions around?

What sort of help are you looking for with your 2" Hayward DE filter multiport?

[Manslick]

Well it probably needs a new gasket.
It is noisy, like it has air in it but no bubbles appear from the inlets.
When switched to rinse, I could see water rise from the notched area. It's hard to turn.
I read an old thread here and someone had to use wood blocks and a clamp to reassemble theirs.
So I'm looking to avoid any gotcha's.
I've seen the rebuild kits on the net but no instructions.

Oops, I actually have the 710XR50.

The above is a link to a PDF manual for the SP0710 vari-flo valve.

I hope it's close enough to mine so I can use it for repair.

An interesting note is the part about placing the valve in the winter position. Never have done that, always used the closed position. Probably why mine is noisy or shot.

More to come - I hope.

Well the valve is rebuilt – kind of. I did not think to mark the handle position relative to the baffle and so it’s now backwards.

It functions perfectly but backwash is now filter.

Oh well, I need to take it apart again anyway. When I went to the parts place I missed to cover o-ring.

It was pretty easy to do. I only had to put the handle and stem assembly in a vise so to hammer out the handle pin with a drift pin. Reassembly required the vise and the death grip to get the pin back in but all in all it was not too bad.

But, the valve is still just as noisy as before. I am thinking the pump may be oversized. Too much flow for the valve. I can feel vibrations when I touch the valve and the noise sounds like, well, too much water being forced thru a valve. I wrapped it with a wet bed sheet that I use to catch old DE, and that dampened some of the high frequency noise.

So the saga continues.

Sorry I forgot to mention the 'notch' on the multi - above the inlet/ outlet ports! However, you figured out that your orientation is 180* different from what the valve says (backwash is filter, recirc is waste, and closed is rinse) - you turned your SP710XR50 into a SP710X50, i.e. a sand filter multi LOL.

If you can get a decent price on the 715 (2") multi - it might be worth while to switch the valve and upgrade the filter pad piping to 2". Just a thought.

It's all on me for not checking the handle orientation.

I took pictures before I started and when I was ready to finish I checked the before pic and it all looked good.

But I had this strange feeling I was playing roulette.

No biggie, I'll fix it Sunday. Off to the lake tomorrow.

Oh, and the action is smoooth now.
