Like many other I am upgrading my pump to a sand filter/SWG. I plan on cutting my liner for the new intake valves. My problem is I don't have any intex plunger valves and I don't want to pay $80 a pop for those. My plan was to use some PVC ball valves. I want to go at 90 degrees off the intake valve then connect the ball valve. Would something like this work? It looks like one end has 2" threads to accept the intake valve then an insert end for PVC then the PVC ball valve.
