A Chock for your Johnny!

I bought this thinking it was going to be a waste of $5. It is now my favorite RV must-have. We have a travel trailer and 5 boys - lots of 'stuff' goes into our Johnny, so after dumping we usually fill up the black tank with water to rinse again. The Johnny Chock holds open the toilet valve so the water will fill the tank. It also is hollow inside so you can add a hose or garden hose to speed the filling of the tank. Great for end-of-season tank rinse out without some hugely expensive flush-out system. Works great for us!

This thing actually works quite well. It keeps the water running into the tank while you are outside. I use it after an initial dump to add clean water to the tank. Then I dump it again and the load of fresh water pushes the remaining waste out. For the price, you can't beat it. You do have to stick your hand in the toilet to place and retrieve it but it is fresh water running at the time so it is not that bad.
