Hi guys, forgive the obvious green-ness in my question. We finally just bought our first Airstream, a 1965
Tradewind. The owner did not have water hooked up. We didn't see any signs of leaking or water damage near or under the potential wet areas tanks, sinks, toilet, shower, etc. In addition, the seller pressurized the system with air to see if we'd find a leak anywhere and it seemed ok (which may or may not be a reliable way to test this). The connections and pipes in the back all seemed tight and intact... so my questions is, how do I test this more accurately? And assuming it checks out okay, can I just leave it as is or is a replacement mandatory/advisable?
Thanks for the help! Jochen
