I hope someone can help with this since it is something I haven't come
across before but suspect it could be a common problem.
A hot water only system is using one of those cylinders that have the cold
feed tank in-built into the top of it. The whole device seems to be split
about one third cold feed to two thirds hot cylinder (with immersion). I am
sure you will all know the name for these things so hope I can be
The problem is that the water runs fine to fill a bath and the pressure
seems ok but after a couple of inches of water is run, the flow just slows
to a dribble. Is this normal with this type of setup? I can see that as
the water is run from the header tank then the pressure will be less, but
not nothing at all, surely.
Could there be some sort of air lock in it, since I drained the header to do
some pipe work. Of course, the finger is now firmly being pointed at me
that my replacing a section of 22mm with 22mm is what has caused the
problem. I suspect it could be the design of the thing and that when all
the hot water is run off then the header is somehow giving a *selective*
fill to the cylinder below. Am I correct?
Thank you all as always for all advice.
