I'm wanting to add a second return at the bottom of the pool to help get the **** off the bottom of the pool. What I'm thinking about doing is getting all new suction and return fittings in addition to the additional second suction so I can get rid of the proprietary intex threads. This will leave me with only the proprietary threads on the intex sand filter to deal with. I'm thinking this might be a better idea so I don't have to buy plunger valves or hoses to just get the nuts. Anyone have thoughts on this?
Also, when I redo the piping, I want to add a connection so I can attach a vacuum if need. My question is, what kind of connection is needed, or does it depend on what kind of vacuum you have?
