John E Davies Posted July 5, 2020 Share Posted July 5, 2020 (edited) Update, Fix a slow drain or airlock, by back flushing. Scroll down to the Nov 6 2020 post. I sometimes like to drain my fresh tank inside the RV bay, this tool saves a big wet mess all over the floor and I don't have to hook up the Land Cruiser to pull the trailer outside. I used a scrap length of 1/2" PEX pipe, a piece of 1/2" automotive heater hose, a 90 degree elbow water hose, and a female 1/2" garden hose adapter. I had all the parts in my scrap bins, so it took all of three minutes to build it. You can reach the tank drain line without even crawling under the trailer, and the elbow will stay in place without any clamp. I timed the drain process with a nearly full fresh tank and it did not take any longer to empty with this adapter and a 25 foot 5/8" garden hose run out the back door, with only 2 feet of drop at the far end - it took about 22 minutes, with the coupler raised six inches.. I like this tool, it is simple and does not leak, quick to use, yet elegant in function.
