I'm about to get a shower pump for a 'panel' unit with body jets: insts. read that it requires 1.5 bar for good performance, but I also want to connect the pumped side to H&C bath taps which at present are lamentably slow (not furred up, newish copper). Looking at the ads. and websites the 1.5 bar units with twin impellers mostly look 'plasticky', whereas the 2.5 and 3 bar units at least have brass inlet and outlet fittings. I *assume* this is good for reliability and performance, am I right? If I go for a 2 bar or above unit, do any of them have adjustable pressure which I can fine-tune after installation?
-- Any help TIA Please reply to Newsgroup
