want to take out a family bath in new build and replace with jet shower is there anythign special that needs to be done so enough water reaches 2nd floor. and what is the procedure for this.

Hi there, you dont say what sort of water supply there is in the home. Is it a combi boiler or do you have multiple bathrooms served from a store water system. hard to advise until inspected. You are best posting this as a job and get some quotes from reputable fitters in your area

Hi, I imagine you are on a combi boiler in a new house. If so you should find no problem with the hot water & the cold will be straight from the mains so the pressure should be good, 1.5bar mimimum normally. Regards Paul
