Water leak / plumbing diagram

[wardhillarch]

Does anybody know where i can get a basic hot / cold plumbing diagram ? I have the ones in the owners manual but they are very vague. I ,m
particularly interested in the splits from the pump supply and city water route. Let me know if you need additional clarification of what im looking
for
Thanks
Jeff

Jeff,

You are now a part of an amazing community of supportive and helping people. We all have a not so hidden agenda of seeing to it that you get to enjoy
both the coach itself and what it can do for you. We all know this already.

Please do both yourself and us a big favor and fill in a sigfile. It should have your real name because we all like to know who it was we helped when
we meet, a short about the coach including major mods because there is some variation and this allows better answers and finally a geographic
reference because there may be someone in striking range that can be great assistance. To do this, go to and scroll
down. Fill it all in and don't worry about the first copy, you will change it a few times. When done, scroll down to , or it will all be
lost.

There are plumbing diagrams available for all the GMC fit coaches, I just do not recall where right now. It is buried in one of the many tech pages
probably on a local chapter site.

It was not OE, but many of the coaches have be fit with a valve to by-pass the potable pump and check valve. This valve both allows you to fill the
potable tank when you are connected to city water and is also helpful if the pump gets air-bound. If you have such, it has to be somewhere near the
potable pump.

Good to have you aboard

Matt

Hey, don't overthink this. Plumbers only need to know 2 things. 1. Crap
don't run uphill, and 2. Pay day comes on Friday. (Grin) Seriously, I have
never seen a coach that did not have some changes to the plumbing. So, no
diagrams are going to be of much help. Simple machines.
