Hi all... Im just doing some work on my bathroom and wish to install some new mixer taps on the basin and a shower bath mixer which all require a minimum of 1bar pressure to operate. I have a gravity fed system which does not do the job...obviously... I cant raise the cold water storage much more than it is...although I dont think this will do enough to make a difference.. My only option now is to install a pump.. the one im looking at is a Salamander Right RGP40 pump. I know this will sort out the hot water... but my question is.. will I need to have one for the cold water as well? Any help would be appreciated regarding installation of the pump... i.e wiring etc..
