Hello people.
Can anybody give a few pointers towards what seems to be an inbalance in water pressure and/or flow between upstairs and downstairs.
I.e if tap is on downstairs and tap in bathroom upstairs is switched on there is a massive reduction in flow upstairs. Also if cistern is filling upstairs then tap upstairs has virtually no flow.The cold water is mains feed and with w/bosch 28si ll combi system. The house is 1950`s and was originally on gravity fed til about 3 years ago. Could the original plumbing be no good for the modern system? I can not see any flow reduction valves etc between up and down stairs pipework. Mains pressure seems to be acceptable downstairs and we are on a water meter, if that has any relevance. The problem applies to both the hot and cold water supply.
Please help if you can. :confused:

It sounds as if you have only just gone there?

The problem seems to be that the mains supply has a limited flow rate and you are expecting more than its able to provide.

The boiler can only give about 10 litres per minute of hot water at this time of year!
