Hi Folks, A Quickie [I should be so lucky!!]
I have just installed a new wash hand basin with 10mm tails. The
resultant flow is [putting it mildly] very poor.
I was thinking of changing the connections to the hot water cylinder
from an indirect to direct feed. Can I do this to my existing cylinder
or, because of the increased pressure will I have to fit a new one.
Thanks for your input


If you mean do away with the gravity CW header tank and feed mains directly
into the hot cylinder, DON'T DO IT!

Normal cylinders are *not* designed for mains pressure. It is very
dangerous - and illegal. Mains pressure cylinders are specially designed -
with lots of safety gizzmos built in - and have to be installed by someone
who has undertaken the appropriate training. You can't legally DIY them.
