Re: Ideas for Shower drain water diverter

We came up with a simple solution for diverting water from our shower drain away from filling our gray water tank.  To help with the best plan of action I removed the driver-side couch in the rear lounge of our 98~MB and opened up the sidewall under the couch next to the shower to inspect the shower pan and drain system.  It is really tight in there with poor access but I figured out that it is much easier to cut into the shower drain pipe after it exits underneath the coach since it is separate from the sink drains.  In our 98~MB the Kitchen and bathroom sink drains run together in a 1-1/2" pipe inside the coach and exit under near the gas fill channel and run directly to the gray tank in the rear of the coach.  The shower drain has a separate 1-1/2" pipe that runs directly to the gray tank separately.  So we cut into that shower drain pipe before it enters the gray tank and added a rubber sani-T fitting with a faucet with a hose bib to connect a hose if needed.  Now we can drain clean shower water on to the ground or out of a hose when taking a clean shower.  It has worked well here on the beach in Baja when you want to shower off the salt water from the ocean but not fill your gray tank. 

Originally I thought it could be easier to add a second shower drain in the shower pan with a hose running out to a hose bib connection for adding a hose if needed.  Now you could plug the existing shower drain hole to the gray tank and water would run down the new drain to your hose.  If you need water to go to the gray tank you would move the plug to the new hose drain and water would run into gray tank like always.  This seemed simple and you decide where the water goes from in the shower.  But the space was very tight to add a second shower drain and over time the chance of a leak made cutting the 1-1/2" pipe to the tank be the easiest choice.

   Thank You for all of You that contributed to this thread, it got me going and now afterward we can decide where our clean rinse off shower water goes and not have to rinse off outside next to the bathroom window with the shower hose and head handed out the window like we use to do. - I know that many have the outside shower unit(we don't)
