Oh Poop!

I was told by an old timer to prime both tanks by putting an enzyme (Thetford eco-smart) plus 5 gallons of water in both the black and gray water tanks. The water helps keep the gaskets pliable on the tank side of the valves. He suggested draining both tanks before a trip and refilling with five gallons of water plus the enzyme stuff so the black tank had fluids for the solids to land in and the gray tank has slosh water with enzymes as well.

Re-prime both tanks after each dumping activity (of the tanks).

I just repaired the same bad seal this weekend. But the white plastic piece that slides into the tank, was also cracked and came apart in my hands, the new replacements are ABS and shouldn't fail. Not a fun job, as I had to cut open the pan to gain access. Where did you order your replacement seals from? Getting hard to find Thetford parts.

I have a 1974 argosy and was just curious to know how to get the grey water valve unstuck so I can drain the tank.

OutDoors RV Mart in NC had them.

The slide on mine was fine but the channel it runs in had some petrified poop in it because the PO lived in the trailer in Florida for quite a few years. Once I took it apart and scrubbed the channel then everything worked as it should.

Mitch.
Is there any movement in the handle?
I have a '74 Argosy as well. The valve on the grey water tank was stuck.
I tapped on it lightly (and I mean lightly) to see if it would move. It moved in slightly. I pulled it back out and repeated tapping on it. With each cycle the handle would move a little farther. Eventually I was able to move it the entire length of operation. It has worked ever since.
