Hi Andrew

Maybe I'm having a blond moment here, but what difference would a dedicated
pipe run make to the water flow? I can see the point about the hot running
out before the cold, but if you have existing 22mm pipes running to say the
bath taps, whats wrong with tapping into them (providing the bath taps
remain off of course)?


The real point is that if you don't take a new pipes back to the tanks
then you haven't followed the instruction (at least all the
instructions I've read for pumps and power showers). So what other bits
of the instructions have you also not followed? Pipe sizing, nicely
flowed bends, etc? I don't mean you, personally, but the OP.

One very important point is to ensure that the piping is such that the
hot water will always run out _before_ the cold.
