How do I get in to look at the city water regulator?

HI, first post here.
Background: 1975 31' International, center bath, double bed. Parked at a lake, nice view, bad road, don't want to take it out again for a long time!
I didn't winterize properly and am paying for it now; I'll do better next fall.
First question: When I hook up "city" water I get water dripping (rather quickly) from inside the pan. The pipe comes up into the bedroom and it isn't wet there, so I'm guessing the break/blowout is in the regulator area.
How do I get to it? Do I have to cut through the exterior shell by the inlet? I can't believe I'd have to go through the floor.
Oh, I'm very NEW at repairing this.
I do have the service manual which is handy, but it only tells what to do with pieces and parts AFTER you get to them.
I appreciate any ideas and/or help.

Water Regulator/Water Pump Location


A belated welcome to the Forums!

I can tell you with some certainty that on a '78 International center bath most of the water pressurizing system is under the false floor in the fowardmost closet on the driver's side opposite of the bathroom. Lift up the floor in the closet and the plumbing is between the wheel well and the closet door.

There is some evidence that on earlier trailers the water pump may be under the sink.....not sure when the changeover of location took place, or if it was model specific...also not sure if in the instances when the water pump was under the sink that the pressure regulator was installed there or not.

Thnaks for the tip

Thank you, Dennis.
I'll look under the closet when I'm out there again.
having this thing 50 miles away does have it's downside!

Pipe runs over floor...

The water pipe comes up in the bedroom and goes through the closet before heading back down under the floor, so Dennis' is different than mine.
Hope there are some other suggestions.

Time to close this thread

After further investigation I've come to the conclusion that the PO has drastically reconfigured the plumbing. So now it's time to redo it completely.
There is NO pressure regulator at all, I'll correct that.
So it's time to close this thread and move on to the next subject.
Now I'll learn about PEX.
