Newbie Airstreamer! 71 Excella - Water Tanks

[africaroots]

Hello All,

We are the proud owners of a 1971 31' Excella complete with what seems to be everything in working condition. We have a few questions that I cant seem to find on here. Our model has the rear bathroom.

1. Filling fresh water tank
- how exactly do I do this? Can someone walk me through this process step by step? I have read a few posts about opening the facets and closing certain valves but I dont have the owners manual to tell me exactly which valves to check.

2. Water pump
- where is the water pump for me to make sure it is in working condition?

Thanks!

Also, if anyone has a plumbing diagram for this model that would help.
