Hello,
I'm inolved in a business that neighbours land with a continual water burst issue - this caused (we beleive) by high pressure. I doubt there is a lot that can be done about the pressure iself as it needs to be high to push up hills I assume (I may be wrong here, just that would be the logic to me).
I have emailed Steve Mogford, Chief Exec of United Utilities about the continual problems and infrastructure in the area - and had a positive response - hopefully something may be done, if not, could always email him again.
Anyone else who wants to, his email address is readily available on Google!
