Our Coachman TT came factory with only a plug in the tank bottom shown in the picture it's the black plug in the center of the pic.
To sanitize the tank for Spring, one must crawl under the camper, install plug removed to drain for winter, fill tank with water and bleach solution ,crawl back under and remove plug to drain,crawl back under in the wet spot and replace plug, refill tank, crawl BACK under in the wet spot to remove plug to flush bleach from tank,crawl BACK under to reinstall plug! WAY too much trouble.
Simple to add a couple of fittings and a 1/4 turn valve to do all that from outside.
Here are the parts:
Not shown is the clamp to attach valve to frame. One could use a Beam Clamp and a pipe hanger(no frame holes) or bolt a clamp to the frame or to somewhere else under the lip of the camper body. That depends on your preference and layout.
Also not shown is the electrical tape I wrapped the clear hose(what I had on hand) to keep all sunlight from the water line thus no algae growth.
Good Luck, Mike
