We have just had our mains water meter changed by the water company. Since then we have found a drop in the cold water pressure at many of the cold taps around the house. There appears to be at least one tap which has reasonable pressure with the others being poor. With the others the water spurts out initially when the tap is turned on but then immediately reduces to a lower pressure. Would this be due to an airlock or air locks in the system? Surely an air lock would stop the water and not just reduce the pressure? How can this be dealt with? Thanks for your help.

Have you checked both internal and external stop taps are fully opened?
Then I would open all taps starting at the
furthest downstream and working back.

It is the flow rate that has reduced.

You can measure that. See the FAQ here for help if required.

The suppliers have a very low minimum flow rate of just 6 litres per minute open pipe which is pretty useless.

Most properties have at least 10 li/min open pipe.

If you cannot find any valves not fully open then measure the flow rate and try calling the supplier back out.
