need some trouble shooting for my sand filter

[flyweed]

hey All. I got our pool up and running this weekend, but having some "issues" with our sand filter. It's a Sta-Rite Cristal Flo T-210WF Sand Filter

and I did the usual backwash and then rinse cycle before kicking it into "filtration" yesterday..but when I turn the level over to the "filtration" mode, I still have some water coming out of the backwash hose. Not a ton, but some. What would cause this? How do I fix it??

Thanks much

It's possible your spider gasket inside is beginning to show signs of wear. Have you been careful to always turn the multiport valve in the same direction, and only switch modes when the pump is in the "OFF" position?

This is usually a sign of a worn spider gasket in the multiport valve. It is a fairly easy diy fix if you can find the gasket, however some manufacturers are making the valves so you have to buy the top part of the valve assembly. Its still an easy fix, just more expensive than the gasket alone. You can check with a full service pool store and see if they have the part available.

Thanks for the speedy replies. Texas- I do only switch "modes' when the pump is off. I don't however only go one direction, I use either direction.

I'll see if I can find the manual and how to remove the spider gasket.

Here's an illustration for my pool sand filter pump head. What parts would I need to replace to make my multiport fully operation again??

Looks like 8, 12, 13, 16 The actual spider gasket is built into 12. The other O-rings might be worn and deformed and could leak after being disturbed

Yeah..I just bit the bullet and ordered the whole top half...it was $81.00 and included ALL items (1-13)

Sometimes it's just better to take one in the shorts and replace the whole thing. Hope it all works-out for you. Good luck!
