the drain is a pain

On our new TT (see sig), the freshwater tank is located between the wheels, with the (plastic) drain just in front of the rear axle. To access it, we have to crawl under the camper and use a wrench to undo (or reinstall) the drain cap, which screws on. We're thinking we may need to do some kind of mod in order to make it easier to drain and fill the tank - perhaps a short hose attached to the existing drain, going to a valve somewhere closer to the edge of the camper. Has anyone done anything like this? If so, how did it work?

    Good Luck, Mike
  • I just did this exact same thing this weekend... my drain had a small ball valve with a plain male end... I had a section of PEX , cut it and placed a 90 degree fitting on it... my PEX runs to the edge of the camper with a new PEX inline ball valve installed on the end... NOW the old ball valve is kept open , and the newly installed one is the only one used...
  • Take the cap to your local hardware store. Purchase the correct size ell, nipple, and valve.
  • Assuming a dump station is available, I've drained my FW tank by just running the water through the pump until it goes dry. The pump is a diaphragm model and won't burn out if run dry for a brief time. This also helps with rinsing out the waste tanks.
  • I don't have a pic of it, but mine was the same way. I have a lot leftover sprinkler parts and found a threaded elbow that fit the drain on the bottom of the tank. Then I added a short piece of pipe and added a ball valve to the end. I am now able to reach between the tires and give it a twist to drain it. I've had it in place for over 10 years and no leaks! :)
