I have an above ground pool with a Hayward sand filter. The problem is the Hayward valve on top of the filter Vari-Flo XL valve model #SPO714TI
the problem is the the valve will not drop back into its full operation position after switching it from one position to another. This alows water to be discharged through the waste position. I have pulled the top for the assembly apart several times cleaned it. After I reassemble it, it dose not seat as it should. I see no obstructions and can not figure out what is keeping it from setting a proper seat to the assembly. When it is off there is full travel and no play in the Handel but as soon as I assemble it, the handle is loose and has play in it thus not seating.
