Constant 'rushing water' noise in pipes!
Help!
Over the last month, we have had a constant rushing water noise in our pipes, both upstairs in the toilet and downstairs at the kitchen sink (both appliances on the mains). We thought the water board had changed their pressures but they haven't.
We noticed that out neightbours drive way has massive puddles in it which don't go away.
If they had a leak, would this effect our plumbing by making this noise?
It is 24/7 quite loud and only goes if you turn the stop cock off and on again but soon returns
Thanks!
