Hi, do you have cold water storage tank and hot water cylinder or a combi?
We have a cold water tank in the loft which feeds in a hot water cylinder on our upstairs landing.
When the stopcock is closed and no water enters the premises, we can still hear the noise.
Hi, i am pretty sure it will be either the ballvalve in the cold water tank, scaled up and will need replacing, this may bypass the stopcock and have its own.check this by
The end of your second sentence does not seem to have got through.
Turning off stopcock, running bath and see if the cold tank is still filling, also listen for tge noise when tap turned off and tank ballvalve closes
The tank is not filling when the stopcock is off. It actually is a direct feed from the stopcock to the ballvalve. The noise is still there when tap is turned off and tank ballvalve closed. It is worth adding we are on a shared underground supply with a neighbouring property.
Ok.do you mind if I get back to you in a couple of hours.im on a job and my phone is terrible for this, thanks
Hi, then it could be the stopcock itself,as sometimes the washer comes loose and makes noise as thecwater goes through
Thank you. I guess we'll now need to find a way of checking that out. Thank you for your advice.
