I see discussions have drifted a little from narrow boat plumbing, however this still seems like the obvious place to ask my question. I have tracked down my plumbing problem to a ‘restriction/blockage’ between my 800L fresh water tank under the well deck and the inlet to my water pump. (The inlet filter is clean!) That’s a run of pipe work approximately 12” long. As well as eliminating filter blockage, I also can only achieve a trickle of water out of the tank even with the tank cap off, so I imagine I don’t have a vent blockage?
So my question is, do any of you chaps have any good ideas how I might clear such a blockage? I have thought about compressed air, but I guess that would only blow any blockage back into the tank?
otherwise I wonder if I’ll be asking a boatyard to chop out my (allegedly stainless) fresh water tank?
Many thanks for your kind assistance.
