Fresh water tank pipe noise
|
Has anyone ever heard a knocking sound coming from the draw pipe (I think) when the fresh water pump turns on? Is it a loose bracket or something else?

Ian, the first photo is of the aft-most section of the tank. The pickup line is copper and could possibly shake and knock against the wall, but I have to wonder what would cause that. Is it possible that there is a slight suction-side air leak? A burst of air into the suction side might cause that, at least I think so. The other end of the copper pickup line in the photo is near the freshwater pump and a hose runs from the line to the pump. When Amel made your SM, they used some sort of sealant between the copper and the hose and 2 hose clamps to help avoid a suction side leak. There will be no evidence of a suction side leak and no water leaking out, just air going in. See the second photo.

I had that sound after the aft most water tank section on my 54 was cleaned. The copper pipe was pushed close to the vertical face of the tank by a monkey fisted boatyard worker during the cleaning process.
