When I flush the loo I receive a rumbling noise coming from the bath. Turning the cold tap on in the bathroom and then reigning it back to a slow dribble stops the noise. Once the cistern stops filling the noise disappears. I think the noise is coming from a vibration in the inlet valve/pipe to the water tank in the loft. The plastic watertank is elevated on a platform in the loft to gravity feed the shower. I think the vibration is running down to the pipework suppling the bath. The hollowness under the bath is having a drum like affect hence the rumbling noise. Anyone.....? Thanks
Pipe hammer is sometimes caused by excessive lengths of unsupported pipework. However something has to start it hammering in the first place and that is probably a worn ballvalve in the toilet cistern. Try changing the ballvalve and, if that doesn't completely cure it, try clipping/supporting the pipework. Good luck, John
> I think the noise is coming from a vibration in the inlet valve/pipe to the water tank in the loft. ..are you sure it's not your mrs playing with her 'toy'?
Want to try the low/no cost diagnostic methods first. incomming pressure problems why not try to balance the pressure at main incomming pipe work. What could you elaborate on that please.
Try changing the ballvalve and, if that doesn't completely cure it, try clipping/supporting the pipework John, the pipe work is nicely supported as far as I can see. Is that the ball valve in the water tank in the loft you're talking about?
Ive had rumbling in my bathroom. But that was back in '73 so im not going to bother you with it right at this moment.
Could be an airlock somewhere. Try when flushing the loo with the lid off, stopping and starting the valve(by lifting the ballcock up and down) about twenty times. This can sometimes close up an airlock. Mr. HandyAndy - really
Could be an airlock somewhere. Try when flushing the loo with the lid off, stopping and starting the valve(by lifting the ballcock up and down) about twenty times. This can sometimes close up an airlock. Tried that and the noise seems to have shifted to coming from the sink in the vanity unit.

Is that the ball valve in the water tank in the loft you're talking about? Yes, it will be. Best if you change the whole b/valve and not to split it inside the tank. This practice can make the new b/valve as noisy as the old one.
Forget the tank in the roof, you don't get water hammer from a low pressure supply. Change the toilet ballvalve as above.
