plumbling schematic help

[j.harvey2006]

I have a 1983 Avion Airstream and I'm needing to find a plumbing schematic for it. I'm needing to do the plumbing in it but don't have a clue to what hose goes to what. The gas water heater has been removed and some of the lines are cut out. Anyone with any information to where I can get one, would be greatly appreciated.

An Avion is not an Airstream. Dr Gradeless site is place to start. A few owners here who will likely show up.

A schematic may not help as lines are not routed with direct correlation to the schematic.

Your best bet is to start at the bathroom sink and follow the hot and cold lines towards the water heater. The cold water will enter the heater at the bottom and the hot exit at the top. If the lines going to the kitchen have been cut off between the bathroom sink and the heater you will have to go to the kitchen sink and blow back through the lines to determine which is which. Once defined they are just Teed into the lines you have defined above.

Hopefully the shower has not been touched and come off the bathroom sink lines.

Plumbing is not too difficult other than where the pipe/tubing runs and how (multiple high and low spots are difficult to winterize without antifreeze).

Cold water comes in, there could be a check valve or shut off valve to keep water from leaving the main entry, possibly a drain leg, and hopefully a pressure regulator.

The cold water goes to the water heater which may or may not have a bypass, then hot water line comes back to the cold water line to wander about the trailer in search of sinks, shower(s) and a toilet.

Someplace on the cold water line a pump will be allowed access to the system to push the fresh water tank water throughout the trailer. The pump should have at least a valve to isolate it from the system when hooked up to city water - this protects the pump and prevents the fresh water tank from continuously filling.

There could also be another drain at the point furthest from city water entry.

Or I could be confused.

The most entertaining aspect is where the lines run and the new yoga postures learned while making repairs.
