Sewer valves, 2000 Alpha Gold 5th Wheel

[Horsefly]

Hello,

I just acquired this unit in a distressed sale without any instructions, etc.

I am currently living in it in cold weather near Topeka, KS (11 degree nights) I have the main sewer outlet open and connected to the park, site, receptacle. However, it appears there are three sewer tanks that do not automatically drain into the main. In one of the hatches, there appears to be one manual and two electric sewer valves and three electric sewer switches.

What is the sequence for emptying the various tanks? Do you turn on a switch and open a valve or vice versa? Also, of the two electric looking valves, which one controls what? And, are they automatic when you flip a switch or what? On the manual valve in this hatch. I pulled it and I think it was the grey water tank that began to empty down the main.

I tried the electric switches one at a time for about 10 seconds. Only on one of them did I hear any elctro/mechanical noise. Does that mean that some sewer valve is not working? If an electric valve is not working, I suppose one could open it manually, Huh?

On my control panel inside, I notice my Galley Tank is filling up.

Help on how all this works and which valve is for what would be sincerely appreciated.

Cordially,
Horsefly

First !. I cannot address your make unit as I've never owned one. The electric valves open by a 12V solenoid attached to the valve. When you flip the switch it opens the valve until you move the switch to off, then closes the valve. In that temperature I suggest leaving all your dump valves closed until the tanks are over 1/2 full. When you do dump the tanks the black tank is first to be emptied, followed by the gray tanks. This eliminates the sewer hose from freezing and creating a blockage. Label that one valve you know what it opens, then when you open other valves (one at a time) you can determine what tank it drains.
Sorry I can't be more help, others will soon see your questions and offer theirs (which is usually better than mine)

You can buy clear bayonet fittings to put in line in the sewage drain hose. The reason for this is so that when you are back flushing your sewage tank you can determine when you've got all the "stuff" out.
Another tip.....don not leave the sewage drain valve open. If it is left open the all the liquid will drain off and the tank will retain the solids which will harden without liquid. It's better to allow the black tank to fill at least 1/2 before emptying.
Sorry I can't help with your specific coach.
