I have a portable Hayward Superpump that I bring with me during pool openings for algae cleanup. I'd like to be able to convert its output to that of a trash pump. What I mean is I want a 3 inch brass male fitting on the Superpump so I can connect my 3 inch trash pump discharge hose. The reason for this is so I can use the same hose for both applications. I usually used regular 1 1/2 vacuum hose but it takes up half the truck to have 200 feet of that on hand.
Can you walk me through how to do this? I'm looking for a strong solution, not just a rubber coupler.
