I've inherited a power shower consisting of a Triton LP4000
thermostatic mixer and a Wickes twin impeller pump. Unfortunately I
seem to have a little seepage from around the mixer cartridge, (which,
incidentally is a new cartridge I have installed in the original
housing). On contacting Triton, they suggest that the LP4000 is not
designed to be used with pumped systems above 1 bar, but I don't know
how much 'umph' our pump is in fact putting out.
Hi,

Might be possible to install a pressure relief valve to bleed off
excess pressure back to the piping before the pump.

cheers,
Pete
