I have a 1986 carver 3607 aft cabin that we just bought was trying to figure out why neither toilet when I turned the pump on there was no water going into the toilets so I removed the cover on the pump where the impeller is supposed to be and there was no impeller in the casing on either toilet somebody had removed them and there were no water lines hooked to where the impeller is it was hooked directly to the top of the back side of the toilet the toilet in the rear bedroom has 2 lines coming out of the floor 1 is plugged off and the other one is hooked up and the toilet in the front of the yacht has only 1 line coming out of the wall so I started to trace lines and seen they went into the fresh water side and they put a solenoid and it controls it by a switch right beside where you turn the motor on for the toilet to flush I checked with the marina and they said it should draw from the raw water I would like to make it back to run off raw water as it should instead of using all the fresh water just for the toilets does anybody know where I could get a diagram that shows where the lines for the toilets are supposed to run and hook up at to go to the raw water? I know its not original to come off the fresh water because it is shark bite couplings where they cut the cold water lines to re route to the fresh water tank.
