Nice top limit


That's how I manage 2 showers at the same time.




That's what I'd like. I have my central distribution pipework in 22mm,
with separate drops in 15mm to the kitchen, bathroom, shower room (when
done) and outside. That's a happy coincidence of having the under stair
cupboard (actually a big walk in cupboard) dead centre and between the
boiler site and everything else.

I am also including flow limiting valves (BES, they take an insertable
cartridge available in 8 or so flow rates) to balance the system - so
running a bath will not starve everything else - and so that a tap on
full in a small basin does not a) blow back in your face; b) defeat the
basin overflow. Rather nifty little valves that include a full bore
isolator too.
