Water Pressure

I live in a row of 100 year old cottages serviced by a common lead water pipe. The lead pipe has a build up on its internal diameter. Quite a good idea with it being lead.............

Neighbours have got that fed up with low water pressure over the years that they have had a new plastic pipe plumbed in from the main pipe outside the front.

Tonight I notice higher pressure from the cold downstairs tap that is piped off the rising main.
This is good news. Lets hope it stays.
