Will my pump run 2 membranes or maybe 1? I have not tried anything yet. When I picked it up (RO) everything was in a heap in the floor. All wires were cut with pliers and all pipes were cut with a hack saw. It is going to be a game to figure things out? Some parts are 120v and some is 240? I will get it little by little with a lot of help on here. Thanks Vernon
