2004 keystone cougar. Just recently our water pressure has been super low, hardly existent. We thought maybe it was frozen pipes, but we disconnected the pipe that goes into our 5th wheel and water came spurting out. When we turn the faucet on theres a quick spurt like we have good water pressure, then it goes to hardly coming out. We havent done anything differently. The only thing I can think of is I was moving stuff around in the under carriage and moved something up against the small tubes underneath. But I'm pretty sure the parts of the tubes it brushed against weren't valves that managed the pressure. What could be wrong and where is all the water going that's coming from the hose connection?
