Hi Ya'll,
I live in Texas and mostly use our Excel 37 5th wheel as our a lake house. I've hav it for about 5 years and the water pressure inside is just pitiful. Olnly a bit more that a trickle.

Outside the hose pressure is about 45 lbs and would blow your hat off but inside it takes about one min to get a glass of water. I've tried changing the pressure reducer and even going with out it to no avail.
I'm thinking maybe there is a trick to this or maybe a valve I don't know about or Something. I'm tempted to re-plumb it with household plumbing ... or push it off a cliff. Any ideas for me to check?
