This is a typical water fill on a vintage trailer. Lift the lid and fill the tank with water. It connects to the trailer with 4 screws. Use putty tape to seal it before you install it.

This is a typical water drain and city water hook up. The drain simply comes from the sink drain and drains onto the ground. The city water hook up connects to a hose and supplies water directly to a faucet at the sink.

This is a typical hand pump. This trailer does not have a city water hook up. You fill the tank with water and pump it into the sink by hand. These are about $30 at rv supply stores, they are easily replaced with 2 screws and a hose clamp.

This is a typical faucet for a city water connection. Once the water is connected, turn the handle and water enters the sink. Many vintage trailers will only have a city water connection. Many will have a pump and a city water faucet.

This is typical plumming for a sink drain. It has a "P" trap which is unnecessary unless you have a holding tank. Holding tanks are not present unless you have a bathroom and are creating "Black" water. A kitchen sink produces "Grey" water. The P trap prevents foul odors from entering the cabin. The plumming allows water to drain outside. This also has a vent above the drain for eliminating odors. Again, an unnecessary vent unless you have a holding tank.
This is plumming that has been "Jerry Rigged". It probably leaked and instead of fixing it, they just put on a hose to the outside drain. This is a fine modification. They've eliminated the P trap and the extra vent.
This is a much better drain system. It simply drains onto the ground underneath the trailer instead of down the side. Genius.
