When we moved into our home [300 yrs old] the previous owners had renovated the ensuite but had fitted an electric pump as the water pressure was almost non existant yet not too bad elsewhere. We didn't like the noise as it had to be on all the time so we changed to an unvented system which did improve the situation but we did notice that if the bath was running the pressure in the basin taps was reduced considerably. We have since renovated the family bathroom consisting of a bath, separate shower, basin and wc. When the bath taps are fully turned no water will come from any other item. If the bath taps are slightly running then other items can be used with a reduced pressure. Is this normal? We understood the unvented system would give us good pressure under any situation. Look forward to your reply. Thank you Keith XXXXXX
Unvented system put in 2 months ago. No change made to mains water pipe.

Generally the pressure is good. The kitchen tap has excellent pressure direct from mains. It is only the bathrooms that are the problem.
Looks like inlet pipe is lead- all other pipes are copper. i understand your point about flow and pressure. only other thing suggested by a friend was that header tank could be pressured more
looks like inlet pipe is lead- all other pipes are copper. Not getting much help from installer of unvented system
