I own a Hayward s200 sand filter . I have two questions . Does anyone know what type of pipe thread Hayward uses . On there bulk head fitting that go on the side of the tank . They are a two inch thread but just a hair larger than a regular two inch pipe thread . Other question I need to move my multi port valve about 8 inches away from the tank . Do they make a pvc fitting or adapter that can screw into the bulk head fitting then into the multi port valve . If the had a coupler that you could buy that had the compression typed slip nut that pvc could be glued into them a slip coupler with the male threads that the bulk head fitting has that would work . I’m basically looking for an extension in between the filter housing and multi port valve . I posted a pic . It would be an extension between #24 and #27
