Hope someone can give me some advise. I have recently had installed a
new bathroom suite which has a new metro vertical 3 hole shower valve
and bath filler fitted to the wall. The suite was purchased from
bathstore. With the old standard taps and bath the fill rate was
pretty good with good pressure, however with this new fancy gizmo it
takes ages to fill the bath. The plumber (who has done a good job)
says it all seems to be working correctly and I will need to get a
pump fitted. Before I go down this route I would like a second
We have a bath in our en-suite and the pressure in there is fine with
Sounds like you've got taps which are designed for mains pressure hot and
cold, but are only supplying low pressure to them from a gravity system.
When you say the 'pressure' is fine in the en-suite, you probably mean that
the *flow* is fine 'cos the taps work happily with low pressure. What
happens if you put your thumb over a tap spout a) in the new bathroom and b)
in the en-suite, and turn on the tap. Can you stop the water coming out in
Thanks for the response. Here is what I have done.
I have tested the ensuite bath and I can hold my thumb over the hot
and cold tap with them both full on. I can also do this for the sink
in the en suite for the hot but not the cold (no surprise)
I am therefore assuming that you are correct and that the flow is fine
but there is a lack of pressure to fill the new bath or run the new
shower. I am also assuming a pump is required.
An idea of a good one to buy (cheap but good) or an alternative would
be very helpful
I had the same problem with a new suite bought from B&Q. I asked if it
was OK with gravity feed and they said "yes of course" like I was some
kind of idiot. After installing it we found we now need to start
filling the bath about 15 minutes before we want to get in it. I went
back to B&Q, their response, "no one else has complained". I finally
tracked down the manufacturer of the fancy taps and spoke to their
technical department to discover they need 1 bar pressure to deliver
adequate flow. Obviously with our gravity system the pressure is about
0.2 bar. Just got to work out how to mount the cold water tank on the
