2004 Sun Voyager

[Rincon Schooner]

Hello All, We just acquired a beautiful classic GulfStream Sun Voyager 8379 and we use it to spend time at the beach.... two days at a time. Since there are no hook-ups, two days at a time works perfect for us, and it’s close. I want to drain the remaining water in the fresh water tank and have been unable to find the valve. Of course, I have been dumping the black and gray, and usually the fresh water is close to empty. This time we came home early and I want to drain and refresh the tank. Is there a valve somewhere that I’m missing? I shouldn’t have to run the water pump to drain the fresh water into the gray water tank. Please, anyone, .... what is the answer?... Thank you in advance, Rob Smith.

Rob,

We have a 2004 Model 8351 so might be different on your unit but there should be a drain valve on the water line going from the tank to the suction side of the water pump in the same compartment as the pump.

Hope that helps.

On my 2000 Sun Voyager, the drains are in a separate bay on the curb side, where the plumbing manifold is.

Under your unit will be low point drains. Some units (RV's) have the valves hanging under the unit. Some valves are inside. Under the unit you can most times find by simple visual inspection lying on your back under the unit. There are three, one for cold water, one for hot water, then a third that is the fresh water tank.
Some RV's have the low point valves inside the unit. For fresh water tank drain, first find the tank. It will be directly inside, at the tank fill port you find on outside of unit. Pull whatever cover you need to pull (under dinette bench seat, or under bed, etc) and look around perimeter of tank. You will find a connection low on the tank with a valve. Pretty common to find t-handle poppet valves.
Since yours is a Class A, there very well may be all the valves mentioned located inside your water service area (compartment for for water/sewer service). Look along side of the compartment. Clear as a Frappuccino? Hope this helps a little.
