The water system is relatively simple, even though it looks confusing at first.
Someone with a manual might be able to send you a diagram.
The system has several provisions for draining the lines, for winterizing, etc.
You will find drain taps near the bathroom area, and under the kitchen sink.
The water comes inside the trailer through the city water hookup, then to a pressure regulator, and then enters the faucets through several t's. The cold water side also has a feed to the water heater. Your water storage tank and it's plumbing simply feed into the fresh water supply after the water pump, which is usually protected by a one way valve, to keep city water pressure away from the pump.
My 1971 has 3 valves under the sink, two for draining the water lines ( hot and cold) and one to drain the water tank.
Then under the bathroom sink, there's 2 more drain valves, both for draining the hot and cold water lines in the rear of the trailer. There's also a shutoff valve for the toilet's water supply.
Everything is then connected to by copper lines. I hope this very basic description helps.
