Buzz Posted January 6, 2022 Share Posted January 6, 2022 In our old house we suffered from every time someone turned a tap on or flushed a toilet the shower would slow to a dribble i assume this was because they were on the same "line" to prevent this in our new build is it worth having the bathrooms on independent water lines , 1 for each room ? Or us there a better solution? Link to comment Share on other sites More sharing options...
joe90 Posted January 6, 2022 Share Posted January 6, 2022 With my new build I used hep20 and fed everything from a pair of manifolds (hot and cold) you still need to make sure your incoming flow rate and pressure are ok. Link to comment Share on other sites More sharing options...
Buzz Posted January 6, 2022 Author Share Posted January 6, 2022 Thanks @joe90, are you saying one feed into a manifold with multiple feeds out for hot water and the same for the cold water ? Link to comment Share on other sites More sharing options...
PeterW Posted January 6, 2022 Share Posted January 6, 2022 First things to check are the static and dynamic water pressure and the flow rate of the new supply. Then decide on your water heating strategy, and then design the hot and cold system around this. Manifolds won’t fix poor flow or pressure, so you need to start from the beginning. 1 Link to comment Share on other sites More sharing options...
Buzz Posted January 6, 2022 Author Share Posted January 6, 2022 Thanks @PeterW, problem is we are not connected yet , is there any way of finding this out before connection? I was with anglian water today and know it will be connected to the main line on the other side of the road . Link to comment Share on other sites More sharing options...

Yes, I did mine like this, cold on the left and hot on the right (I split one to feed two toilets rather than another manifold bit). The 22mm fed pipes had shut off valves above pic in case they needed isolation. Edited January 6, 2022 by joe90 1 Link to comment Share on other sites More sharing options...

No idea but if the shower is turned off other taps should not effect it!!! ?♂️ Edited January 6, 2022 by joe90 Link to comment Share on other sites More sharing options...
