Down Pipe Causing Water Hammer and Gurgling Drains In Block of Flats?

Postby stircastle » Wed Mar 16, 2016 7:51 pm

Hi :)

For a few months now the block of flats I'm in (one above, one below) have suffered from water hammer and I have a gurgling bath the problem the communal down pipe outside? Could there be a blockage not letting air in somewhere? The neighbours aren't bothered about it but I'm concerned the pipes will get damaged and also the noise is annoying. I hear my neighbours washing machine fill and drain and the thudding sound is very obvious. I don't think anybody has had any work done recently...
Any help would be greatly appreciated :)

Simply Build It

Not entirely sure these two problems are connected ED. Water hammr is a result of an inlet valve in a water supply pipe juddering and not allowing a smooth flow of water whereas Gurgling basins etc are a result of the water in a waste trap being sucked out as water from another appliance flows pas it. The flowing water is followed by a vacuum which sucks at water in the traps it passes. You can read more about water hammer here

And more about gurgling traps here

Good lock and do let us know how you get on.
