Plumbing Question on '67 Safari

Hi - We just bought a '67 Safari. Checked out the electrical and it's great. I just hooked up city water to it, and I'm not getting any water pressure. I can't seem to find a shut-off valve anywhere, but there is "some type" of valve other other(?) right after the input regulator. Anyone have any ideas on why we may not be getting any pressure to anywhere in it? Thanks much

Many of our vintage Airstreams have a "pressure regulator" in the circuit to protect the plumbing from high water pressure. (Airstreams like 40 psi water pressure.) The pressure regulator prevents high water pressure by making the water open a plunger with a spring behind it.

If your pressure regulator is stuck shut, then the water pressure can't open it and you don't get any water flow in your trailer's system.

This is one cause for lack of city water pressure and flow in your trailer.

You can verify this by adding water to your fresh water tank, turning on your 12v water pump, and verifying you have water pressure and flow to your faucets in the trailer. Pressurizing your water system with the 12v pump does not involve the city water pressure regulator.

Our old trailers were originally plumbed in copper. They are a bugger to work on. Replacing an old pressure regulator is a real job in copper. You will find the PEX pipe and fittings are your friends.

Let us know when you find the problem.

Similar experience when we first hooked city water up to our '66 Safari. No pressure, but I could hear water flowing. Massive leak under the streetside rear gaucho!

Replaced all the water lines with PEX. No problem since.

My old 67 Safari had a tap just inside the back hatch that had to be turned on when hooked to city water.
