Hi, I searched the site but didn't find the answer. This must be a common thing though.
When the HW is turned on, there is a groaning noise from the back of the HW tank at the outlet. I can't see back there but I can get my hand on it and there is a vibration at the right-angle in the plastic pipe just as it leaves the tank. There is no vibration in the brass outlet. It is worse with more flow. The HW pressure seems the same as usual, but it is very slightly less then the CW flow, which is what I would expect.
I'm suspecting those white deposits I flush out of the tank every lay-up time are partially plugging the outlet.
Would that be right?
And where would I find a competent dwarf to crawl in there, take it apart and clean it?
Thanks Rankjo
