Have a 6 way Praher (tm-12-l) valve on top of sand filter, Came with used house we bought, no book on filter, Need find out what kind of sand filter we have also where can I find owners manual, or info on how to change out sand, also need to replace valve, as it has a crack in pipe connection ? Note system was winterized but service company did poor job , did not leak last summer . Thanks

Hi Doug, This would be the correct replacement valve for your filter. We do have a good Video on How to Replace the Sand in Your Pool Filter which should be of help to you.

Does the valve assembly come with the gasket / o-ring to mount to tank?

A  Answered on 5/29/2015 by InyoPools Product Specialist Patrick P.

No it does not come with the o-ring that goes between the valve and the tank. This o-ring is actually considered part of the filter so could you let us know the make and model of your filter?

We had the original valve on our pool which is a 2001 above ground. It took 2 years to finally get the right replacement abd it is working great.

Had to remove old valve and when we replaced sand before installing new one, we did not notice a little sand got itself under the stand pipe and could not get the valve to seal. Got a shower or two until the right person told us to check the height of the pipe and lo and behold, that was our sealing problem. Now all is well.
