I was thinking of changing the mixer tap on our bath to one of these
beasties from Screwfix:-
Anyone used one of these? If so are they any good?
The current hot water system is a standard gravity fed system with
header tank and indirect cylinder, with 22mm feeds to the bath taps.
However I am planning to fit a combi shortly and do away with the tanks.
Which would then result in mains pressure/fed hot and cold water being
fed to the taps.
Would I be right in thinking I would need to fit double check valves
before the taps? (since the shower head on the new mixer could come into
contact with "grey" water)?
If so, do I need one on the hot tap as well, or does a combi normally
include one in its design?
