I am installing a thermostatic mixer shower in my bathroom. I was going to install a pump in the airing cupboard and then install all the usual piping as this is a gravity fed system. HOWEVER her indoors with all here wisdom has decided she would like to have a combi boiler installed in the summer hence the wasted money on extra piping and a shower pump that will not be any use when the combi boiler is fitted. WHere is the best place to tee off from the hot and cold supplies to go direct to the shower mixer. For instance could I go from the pipes that supply the bath (22mm for the hot and 15mm for the cold) . All help gratefully apreciated.
