Easy open/close Travato fresh water tank drain valve

A modified 1 1/2" Valterra sliding gate valve that screws into the fresh water tank drain socket. No tool needed and no plumbers tape - it uses an o-ring (supplied) for the seal. Reach down and pull the handle to drain the tank; push it back in to close. No more crawling, etc. I have been working on this design for some time now getting the parts just right!
PLEASE NOTE: this mod is only for newer Travatos that have the fresh water tank mounted underneath the van, as shown in my photos.
Installation: remove the original drain plug using a wrench. clean the threaded socket to remove any stray material, plumbers grease, etc. Insert the threaded portion into the socket and tighten until the o-ring makes contact. It should spin freely until the o-ring hits. Turn about 1/2 to 3/4 turn more, then turn backward slightly;(maybe 1/8 turn?) to seat the o-ring. (thanks Dad!)
There are 2 3mm screws that can be loosened to allow turning the gate valve so the handle points in the right direction (see photos). PLEASE practice doing this BEFORE you install this on your water tank so you have a feel for how this works. There are detents (slots) these screws fit into. Tighten only enough to stop the handle from rotating - do not over tighten.
