protected from stone damage by steel
Most off road camper trailers that
come with an underslung water tank do not have a drain facility to
empty the tank. If you are not using your
camper trailer for any length of time it is a good idea to empty the
water from the tank to avoid bacterial growth.
I like browsing the shelves of
various shops for ideas to potential camper trailer projects & came
across a PVC 12mm T fitting with a tap at Jayco in Newcastle. This
tap is used to switch between two water tanks to a common outlet &
has a positive lock holding it in position. First thought
was, could this be used as a drain for the water tank.
Before putting this article
together I wanted to make sure my idea worked, so after 10,000
kilometres over highway, dirt road & tracks it has not accidently
turned on or dripped any water. As the saying goes it is a good idea
not to put all your water in the one container. We always carry a
couple of water jerry's.
First up I fitted a ninety degree
12mm screw-in PVC fitting onto the tank with a barbed fitting on the
other end. This made the tap sit flush to the side of the tank &
inside the edge of the tank's steel stoneguard. Do not use thread
tape on the PVC fitting as it will flatten the thread of both the
fitting & the PVC tank. You should be able to just screw the fitting
in until it bottoms out & seals itself in the bottom of the hole.
You can also wipe a little non acid grade silastic to the last few
threads of the fitting to seal it.
I added a short length of food
grade 12mm hosing & then the tap, both secured by hose clamps. The T
runs to the handpump on the side of the camper.
For a quick walk around visual
check I added white paint to indicate the flow of water. Pointing
towards the outlet hosing goes to the handpump & when to the end it
works as a drain.
