I had a bathroom completely refitted about 3 years ago. After the job was done, the flow at the taps, showerhead etc was significantly reduced. The guy who did the work told me that the old, wide fittings were no longer available. Of course, this was bull****. It takes an age to fill the bath and the shower is *just* adequate on full bore.

Is there any virtue in fitting a pump to the bathroom supply only?


I fitted one to the hot water supply to the shower/bath, and it's been
working very well for a few years now. Missus wanted a mixer tap/shower
thing, and I didn't know at the time that gravity feed would only push a
trickle of water through it (although I believe that there are
low-pressure mixers out there). Worse, the mains pressure can actually
push cold water backwards and up into the header tank.

So I fitted a pump to the hot water only (the cold mains supply has more
than enough pressure). I discovered that the problem of pushing water
backwards still exists (if you turn it to cold, open the tap, and move
it to the hot side) because the pump only works when its flow switch
detects hot water going through it in the normal direction. So I fitted
a flow switch (fortunately, the pump already has contacts for this
purpose) into the cold supply, so now the pump pumps (or attempts to)
the hot water even when only the cold water is flowing.

So, probably not a setup that anyone would recommend if doing it all
from scratch; but now I have something that works very well for me.
