Have you taken a look at the pressure regulator, the bell shaped unit somewhere near the water heater.? I'm told that sand can get in it's diaphram and it can restrict flow. On my last trip at one stop I couldn't get any water flow at the sink off of city water. Toilet and bathroom was fine. At the next stop everything worked fine. Vibration during travel must have reset it.

I am not sure about a 73 but on my 86 there is a check valve just behind the pressure regulator. I had to clean mine out and you would not believe the amount of trash and stuff that was in it. These things were blocking to flow of water. Because of the check valve it did not allow water to flow back out of the city connection so the only way to clean it was to remove it.

Also you say that you had perfect flow and preasure until you arrived back from the shop. Is there any chance that there is sediment in the water supply here? If so this may also be an issue.

Good luck

Don't be afraid to cut the pipe out. If you use Sea Tech or shark Bite fitting keep in mind that there is an O ring in there that makes the seal. A lot of people only push till they feel the first stop, the O ring, and they have leaks. Push till the second stop. These fittings are removable by just pulling back on the sleeve so they are forgiving.

You might want to polish the ends of the copper pipe with fine steel wool or crocus cloth just to get any dirt off before installing the fittings. Don't scratch the pipe just clean it.

WOOOOOHOOOOOOOOOO!!!!! There was a blockage in an elbow fitting. I cut the fitting off and replaced it with braided vinyl tubing, clamped it down and low and behold....water! Thanks for helping this newbie out. You know I took the trailer to 6 different places and not one of them could figure out what was going on (or just didn't want to try). I've been at this for months. I was inches away from throwing up my hands and selling the trailer to the highest bidder. Thanks for giving it some new life! Dave

What was the blockage, solder, dirt, or? Curious minds want to know.

Not sure I would trust vinyl tubing for any length of time against varying city pressures.

Congrats on solving one of the greatest mysteries in the universe! At least from here out you will have an in depth understanding of the water system and should this bugger ever reappear you will be skilled in slaying the dragon.

Vinyl tubing wasn't my first choice either, but I have to reduce from a 5/8's to a 1/2, and I couldn't find a shark bite or watt's quick connect that would do that. But just like any old pipes, you fix one area and exacerbate a leak in another. Anyone know where I can get an auxillary tank for my old Ambassador? Thanks again.

Haven't figuted out what the blockage is yet, I'll have to take a closer look this weekend when time allows. I will be sure to let you know what I find. I am willing to bet it's solder. I had a leak a few months ago and was not getting any pressure. I had an RV repair man fix it. He put the elbow in, got things up and running and sent me on my way with a "don't ever bring this back to me again" remark. The blockage was in the newest addition to the piping. Oh well, he only charged me parts so I won't cry foul on that one. These things have quite the learning curve!

I have bought tanks directly from the manufacture at about 1/2 the retail. It has been a while so I don't have an name or number at this point but do a Google search for RV tanks and you should find several.

They have a wide variety and if I remember will make custom tanks

For the curious. On a previous repair, the shop put an elbow on the line. Apparently, it was a "thermocoupler"??? elbow for some type of temperature control. Anyway, it had a spring in it. The spring built up sediment and that is how the line was clogged. Weird, but that is what happened. Thanks again for all of your help.
