Need Plumbing Diagram 1976 31’ Sov Intl

Hi everyone,
New here. I have the manual, I have called Airstream direct and they told me “we lost those for your year in a fire” So here I am asking for some first hand knowledge, a reference or link to past post for some plumbing help.

Ideally I would like to have a blueprint or photo of the plumbing inside my 1976 31’ Sovereign. Any help would be greatly appreciated.

Thank you

We have refurbished almost every utility in a 29' 1976 International. Replaced the copper pipes with Upinor. Pumps are modular and are just exchange. Only thing I did with the black ABS is to run my solar panel feed down the kitchen vent. Tanks are original. Gray and black shed some of the buildup on the sides. I treat the fresh water tank monthly with very dilute Clorox but am afraid to look inside. I have bolted supports for a larger gray tank but have not yet installed a new tank. Rear bath or bed? What is it you want to do?
