My mains water pipe comes in under the floor in the centre of my house. ( where the old kitchen used to be). I have built a new kitchen 5m to the left of this and a new utility room 5m to the right of this point. My problem is this..... If I can only have one stopcock this means I will have to run pipe from the existing mains pipe to the new kitchen where the stopcock will be located ,then run another pipe from this and run it all the way back to the utility room. It will be easier to T off under the floor and run one pipe to the kitchen and have a stopcock located under the sink, and run the other from the T to the utility room and have another stopcock. Is this doable under Building Regs or does there have to be one stopcock in the property?
