Sand Filter Dial Valve Head?

[ProfitOfDoom]

Some of you might have seen my post a few weeks ago about buying a used pool,well the good news is we got it up and the liber is good and all is well on that side of things,But......The water is almost to the skimmer box so we started hooking up hoses and testing the pump and sand filter. The water kept coming out of the waste port on the dial head,I read that there might be sand in there preventing the handle to lock in the filter position. I took off the head washed it out pretty good with the hose relubed the gasket put it back on,It moved a bit smoother and actually slowed down 95% of water. I moved it around to different settings and it started again,then it slowed down again but it never fully stopped?

Does this mean the valve head is shot? Maybe it just needs to be ran and wash out any crap that was there from moving it around?

This is a jacuzzi sand filter mfm 17/20

Any suggestions Please let me know. Thanks.

I suggest replacing the gasket, and the handle tension spring, if you can find one. Jacuzzi went under about 3-4 yrs ago and parts have been available hit and miss ever since. Try your local pool supplier, they often have older parts kicking around or may have a line on an aftermarket Jacuzzi parts supplier.

Good luck.
