Just sharing my latest project which is to hard-plumb/pipe my Thetford Sanicon Sewer discharge dump line from inside my wet bay to the exterior/underside of my 45' DP for anyone interested in such a project. This project came about owing to a number of factors, 1) For whatever reason (yet to be explained by Newmar), my coach was supplied with a 1-1/2" wide channel exit profile on the outward face of the wet bay basement door apparently intended as a space for the Sanicon hose to exit the bay while allowing the bay door to be closed. When doing so, I found that the profile was too narrow and often resulted in pinching, thus breaking, the hose requiring me to replace it. In addition (and again yet to be explained by Newmar), my coach was not provided with a sewer compartment floor access hatch for routing either the conventional/standard 3"OD or the Sanicon 1-1/2" OD sewer dump hose(s) through. 2) On occasions, I have needed to extend the length of the Sanicon hose in order to reach camp site dump receptacles. This was not easily done and often had me switch back to using my conventional 3" sewer dump system. This modification will enable doing so by using a 2nd section of the Sanicon hose with male/female cam lever coupling fittings attached. 3) When "camped" it is my desire to be able to fully close my wet bay compartment door including such times when the gray water dump valve remains in the open position. Prior to this mod, such was not possible due to closing of the door would result in the pinching off or crimping of either size dump hose. A work in still in progress i'm now awaiting delivery of special ordered PVC fittings and clamp/hangers to connect a clear section of hose to (between Sanicon drain outlet and new Valterra slip gate valve) as well as some strap/clamps I plan to use to secure the piping and cam lever coupler in place. Completion of this project will include making up a separate/spare section of the 1-1/2" Sanicon hose with male/female Cam Lever connections that will permit me to add an additional length up to 21ft when needed. The purpose of the small section of 1-1/2" clear spiral hose is to enable me to witness when dumping is completed (be evidence of clear water).Noteworthy of adding, the Sanicon hose is normally "wet" (retains some fluid likely due to a small amount of internal bypass) so adding the slip gate valve downstream of it is intended to allow my connecting the dump hose by means of the cam-lever couplings without coming into contact with the waste water. It is also being positioned in such a way that appropriate road clearance will be maintained.Meanwhile, here are a few photos of this project....
