1978 Sovereign fresh water valve question

I just connected my fresh water line and then I see what I think is a regulator and two valves. What exactly are the two valves for? I'm new to RVs and a greenhorn to plumbing as well, I have a lot to learn!!

The regulator is to prevent damage to your trailers fixtures and plumbing due to possible excessive pressure from a city water system.

The valves I don't know , I trashed all of my old plumbing....

Someone who knows should chime in here though.

The fact that I am opinionated does not presuppose that I am wrong......

Those should be drain valves for hot and cold water lines. Open them while connected to city water and they should flow with good pressure. If you have original copper pipes they should have red handles.

4rxla is right. Here is a copy of the plumbing page from my 74 Sovereign service manual. See Item 5 at the rear of the AS. The service manual is a valuable aid when working on your AS. If you don't have one you can probably find one on ebay.
