Greetings NewToThis73!

Welcome to the world of Vintage Argosy ownership!

Most of the Argosy coaches had a front mounted water tank immediately below the front windows. In most cases, the tank drain valve is on the streetside between the tank and pump -- on my '78, it is a plastic 1/2-turn valve. Be prepared for a wait as it can take several hours to drain a tank that is close to full. The drain hose goes strait down below the valve and exits the bellypan -- sometime mud daubers or other insects will build nests or create other obstructions that may need to be cleaned out of the flexible vinyl tube.

Good luck with your investigation.

Have you looked for a drain at the bottom of your fresh water tank?

Some installations have a square sheet metal plate in the pan that encloses the tank - you have to remove the plate and you will get access to the drain plug - you'll have to crawl under the trailer to check and see...

It wasn't too convenient to drain these earlier tanks, but it's doable if you want to give it a good flushing, etc...I guess you could run some piping out of the drain fitting to a remote location so it was easier to get too, but you then run the risk of knocking the pipes off on a road hazard and loosing your fresh water...just a thought

We've Got The Same Question!

We just got back from Burning Man and now have to drain our new to us 1959 Overlander's tanks of water. We can't seem to find any valves under the sink area or near/under the tanks, unlike our other Airstreams.

There's got to be a way to do so without running the water through the faucets or siphoning it out.

Any insight and/or advice would be most appreciated.

Thanks in advance!
