Water Pressure Help Needed

[Flossie]

Can anyone give me some help. I have a water supply on a shared supply which has three properties connected. The house in the middle is complaining of really low pressure while the property at the end is fine and the water company have measured just short of 4bar pressure at mine. I am thinking that the house in the middle has internal pipe problems. Can anyone help with how to work out where the problem would be??

Without visiting and testing we cannot work out on the internet!

Static pressure is irrelevant. Its the dynamic flow rate which is important if showers are to be used. Or the open pipe flow rate if no showers. 6 li/min is about the minimum open pipe.

Can you tell me where you would start testing?

i would be expecting 12 to 16 LPM on mains water supply 6 would be very low. poss crushed pipe or stop valve partly shut down.

If there is 4 bar in the pipe and your flow rate is good ( you dont say if it is) then there is a pipe obstruction for the problem house.

Incidentally, if you measure the static pressure in the ' problem' house, I am happy to bet that measures at 4 bar too!

The static pressure is relevant, in that the the pressures at all points should be the same.

If they're not the same, it suggests that you're not measuring the static pressure because there is flow in the system. This could be due to a leak.
