? plumbing problem

nicter

hi. Recently moved to our present bungalow which has twin sinks in the bathroom. When letting water out of either one of them for a good few minutes afterwards you can hear the water "blooping" (like the noise you get when emptying a bottle):(
Anyone have any idea how we can stop this as its annoying particularly at night
Thanks

Probably a partial block in the drain.

If it all seems clear then check the vent as an unvented/blocked vent would produce some noise.

Does the basin waste run into the stack and is it a particularly long run?

Fit an AAV to the pipe run

Both sinks look like this and waste goes down under the cupboard so cant see beyond this bit

Whats an AAV ?

What's with the jubilee clip? Looks a bit odd!

An Air Admittance Valve, It acts like the top of your soil pipe normally would - allowing air in for water to fall without causing a vacuum on u bends.

At the risk of sounding daft ..... Do I need one for each sink and where do you install it ?:o

Possibly someone's DIY version of connecting a 40mm to 32mm pipe.

Its not a jubilee clip its a rubber lined pipe clip
