Thanks for the insights Terry. Just to clarify though, it is a tenement flat - 2 floors up - with a very large room in roof area (which was probably built at the same time as the building, over 150 years ago! And the water mains into the building will not be much younger!!) Apart from going...

......11 if the upstairs tap is turned on by itself, it has very good flow.

Sorry if my info is not clear. 1. There is currently only mains supply cold water in the house, all measures I have given apply only to cold supply direct from the riser via nominal 15mm flexible pipe. 2 There is no combi boiler involved, in fact no hot water supply in the house at all. The...

Indeed. All these problems. I've now had a chance to read the Water Company Report - Suspected Private Underground Burst - Toby Sounding When Open and No Water Being Used. Building Manager needs to investigate. Whether that issue by itself is enough to be causing our problems....? The incoming...

I realised it wasn't absolutely true like for like so I used inverted commas "like for like", and tried to clarify that I meant no extra pipe runs were added, no extra services and the pipes were still nominally 15mm (ie the new flexible 15mm pipes did not replace 22mm copper pipes for example)...

...as I said in my post, the performance of the upstairs toilet was not tested (there seemed no reason to test as the bathroom suite was being replaced straight away). All water pipes in the flat have been upgraded "like-for-like" (ie 15mm but using flexible pipe instead of copper). No new pipes...

......would this be relevant? There is a route I can quite easily take a completely separate pipe from the incoming mains water to the upstairs bathroom and feed everything up there from this separate pipe. Could that make a difference?

Measured flow rate of incoming water mains supply is about 18L/minute. Flow in upstairs bathroom (not yet measured) is "good". If taps on downstairs kitchen sink and downstairs bathroom basin are turned on, the flow upstairs reduces to complete zero. If those tap flows are reduced to a near...
