Tank Dumping

No easy to relocate, and mine didn't work in first place, so no amount of help would fix that Bro.

Yep, mine works fine and I'm not working on both sides of the trailer.

NAP1947,

First let me say my backflush installed on trailer did NOT work. The check valve was installed backwards and it is in the wall behind bathroom sink. Adding a backflush to drivers side is easy, you need a length of hose, a check valve and a standard hose nipple. You can make a bracket or buy one of the kits that has a bracket (CAMCO 40123) with it to mount the hose nipple. Simply remove your existing hose connection at the black tank, attach your procured hose run it to bracket and hose nipple mounted on drivers side, put a check valve in the line and your done. I added some mounting hardware to trailer floor to secure hose against floor, works fine and it is mounted right next to black drain.

Was camping last week and weekend in our larger trailer.  It was cold.  We didn't have any problems with fresh water freezing (enclosed underbelly and heated hose).  As we were leaving I found the black tank's drain valve frozen.  The two grey tank valves were not.  Emptied one grey tank.  So we're going back camping in a couple of weeks.  Will have to dump as we arrive.  The alternatives are to use our portable tank but then we have no where to dump it or drag the trailer somewhere that allows dumping.  Might as well wait for the next trip.

I’m really glad I read this thread. I didn’t know I had a black water flush. I only looked around on the side with the valves and didn’t think to look on the opposite side!
