Hi, I've just fitted some second hand edwardian-type taps to a bath.
The taps look about 5 years old. The problem is that the hot water flow
is useless around 1 litr/min. If I take the washer out there's a
reasonably powerful very thin (3mm) jet which sprays as far as the
other end of the bath.Looking at the underside of the taps (when
unscrewed from the pillars) there's a black grommet type thing there
with a hole ab out 3mm wide. Looking at other taps of this type the
hole is bigger and it's just metal there no rubber. I've bought some
new ones since and they work fine but I'm still baffled by these older
taps. The system is gravity fed could these taps be for MHW pressure
systems only?

Thanks to any replies

Jon
