Water Leak

[Aunt Fanny]

I just purchased a 1995 Land Yacht to live in this winter. When we hooked the water to it water came pouring out back around the spare tire. Water is running in bathroom but trickles in kitchen. Any tips to where it most likely is leaking would be appreciated!
Thanks

Is the water running out the belly pan? Or out of a tube thru the belly pan?
If it is out of a tube. Look for low point drain valve open.
It may be a pressure relief device since you have water pressure in the bath. This device releases the pressure by dumping water until the pressure set limit is met. If constant high pressure it will dump water continuously.
This device is not a regulator, it is a releif valve.
What is the city water pressure at your location.
I would try an external pressure regulator at the water source.
Does water run out when you use the pump?
If so. Look for a leak.
