Doublewide is six years old, just had it inspected in June. No problems found. Today we lost almost all Cold water pressure in one bathroom. The whole rest of the house is fine. Hot water is not affected. The toilet takes ten minutes to refill and while it is doing so there is no cold water pressure to the shower at all. It maybe trickles or drips. There is no apparent leakage or damage under the house. If we leave it alone for a while the shower will work but then peters down.

What type of piping do you have. I have found collapsed or crimped poly lines on mobile homes.
