RE: Holding tank and water tank=which side for pump out and fill???
Sounds to me like you may have a below waterline overboard pump out and an incorrect valve is open and you are pulling sea water.* It is highly doubtful that you are pulling freshwater/seawater through the toilet.* My overboard through hull exits below the waterline.* I keep it off with the handle removed to make sure I am in compliance with any laws concerning this equipment.* Also keep it closed to prevent issues such as you have explained or accidental flooding of the boat due to failures in the system.* Hope this helps.* Leon
