Low pressure All aspects of plumbing questions and answers, help, tips and information

[saintmackem]

Hi,
Have a house with 2 bathrooms. First is all well and good with no probs with toliet, sink, bath or shower (mixer type).
In the other, an ensuite, the sink, toilet and shower (mixer type) all suffer from low pressure on both hot and cold. I have traced the pipes back to where they join those form the other bathroom. All seems ok and all is in 15mm copper. Can not find any valves which might be half closed or something. One section is hidden behind a boxed in unit. All I can think of is that both the hot and cold pipes are blocked or kinked - but this would have to be exactly the same on both hot and cold as they both seem to have the same amount of low pressure.
Any ideas?

hi saintmackem if your en suite is on different upper level this could explain different pressure as i suspect they are supplied by header tank in roof all the best john

Thanks, but no they are on the same level...
