2 tank fresh water system

[canadianjason]

Does anyone know how the dual tank system hooks up to the pump? The previous owner monkeyed with the plumbing and I would like to put it back theway it should be. It is a 2006 30ft zinger crossfire toy hauler.

Hi Jason: We are from Edmonton as well and just picked up our new Zinger 33FK and love it so far.
Have never seen a unit with 2 FW tanks but that would be a bonus. Maybe they are hooked up like my trucks I had and there is a crossover line which has a valve on it so when one tank is dry you open valve so pump can pull water which is then transferred to first tank. I am just guessing but hope this may help.
Good luck and great camping!!

I also have two tanks. If connected similarly, both tank lines attach to a valve tee (furtherest back). Turning it determines which tank is operating. There is another tee valve before the pump and it only goes up and is vented. I always leave this valve closed to the vent or you will just suck air. I think it might be used if the backflow valve in the pump fails when on city water. If that happened, you would fill your tank/s when trying to use the city supply and have to disconnect.

It also may be used for winterizing but we don't do that here.

I have a FW main tank and a galley tank. I also have two gray water tanks. The galley for the kitchen, main tank for the shower and bathroom.
