Iíve spent the last few days taking stock of my new (to me) 1978 Sovereign
. Iíve been trying to leverage the other posts here (and am a newbie) but still have some questions Iíd love help with. Please forgive the number of questions but I thought it was more efficient to gather them in one thread versus a bunch of individual ones (and please excuse my ignorance of plumbing terminology).
Picture 1 (Black.grey connection) Ė
We are going to use a composting toilet so I was already planning to combine the two tanks. Today I tested the tanks and neither leakÖbut the Thetford valve leaks on the black tank. Should I just cut all this out, make a T connection out of pipe (connecting the two tanks and then flowing out) and then put a valve on the outside of the Airstream (so if it breaks I donít have to pull apart the belly pan to fix it)?
Do these tanks have any specific threading on them? Anything else I should watch out for? I have 22 and 26 semi-opaque tanks. Any reason I canít use SeeLevel monitors on these?
Picture 2 (Fresh water)
Ė I think Iíve identified everything here but please correct me if Iím wrong. After the water goes through the pump it goes into the copper pipe which has a T going to ďmystery sectionĒ (question on that in next pic) and other side coming in on left of pic. It splits to the spigot, behind which controls a 4 inch tube going out the trailer. I assume this is the fresh tank drain(?) Would it not make sense to move this outside the trailer for ease of working on it and so I donít to leave this section exposed?
The yellow continues to the red outlined plastic pipe and looped around to feed the hot water heater (I think).
Picture 3 (Mystery copper pipe)
Ė As mentioned above, this comes out of the water pump, does some zig-zagging and then goes to the outside of the trailer and is capped right behind the dump valves. Any clue what this is and do I need it?
Picture 4 (Bent gas line) Ė
I inspected the whole gas line and it nearly
all looks good (no bends/cracks) and I plan to use the soap test. That said, these bends are about 1 foot from where is starts down the A part of the trailer frame. Any reason I canít just cut it here and replace the short section between here and the tank? Seems like it would be a waste to pull out the whole thing if this ends up being the only compromised section.
Ė Currently my fresh water inlet is just a hole in the side of the trailer (i.e., no threaded screws). Should I replace it with a threaded one?
I was just wondering if there were ever issues running into hoses without threaded ends (or in a pinch from plastic tanks). Also I was wondering how to know when itís full (if the tank monitor is inside)(?)
Thank you all so much for your help! I really appreciate it and definitely couldnít do it without you!
