Hayward Multiport Valve

[trudera]

Folks,

I need some guidance. When my pump shuts off I hear a hissing sound in the multiport valve and water draining . My gut instinct is the spider gasket is done. The filter is a hayward S244t, the multipost valve is an SP0714TC and the spider gasket key/seal is SP0714C. The key seal has never been replaced and the unit is 10 years old. Now my conundrum is that I cannot find a SP0714C. I have come accross SPX0714CA which says replaces SP0714A, SP714A, SP0714CA. Does anyone know the correct replacement for SP0714C?

Thanks in advance,

Randy

Randy, one of our guys like @Bama Rambler or @JohnT might know. Or you may try giving the folks over at InyoPools.com a quick call. They should have a cross-reference catelog to help confirm.

The SPX0714CA is the replacement for the SP0714C.

Since you say that it's hissing, it sounds like you may have a suction side air leak somewhere. A hissing sound and water draining out of the filter is usually an indicator of that.

I do have a suction, went and put lube on all the gaskets. Have not run pump since doing so. I thought the hissing sound was a result of a bad spider gasket letting air back in through the backwash.

 

[Bama Rambler]

It's possible that, that's the case, but you'd likely have water leaking out the backwash in that case as well.

My backwash is a solid line to my ditch underground so I would never notice a leak.

You might just need to lubricate the stem o-ring with some silicone lubricant.

If you need a new diverter, you can get the SPX714CA or you can get the whole top part SPX714BA.
