Greetings, I have just purchased a new property and have noticed that the guest toilet(downstairs) tap(cold) causes a vibrating/rumbling noise of the pipes when it is opened. If it is opened wider it does stop. Has anybody got any ideas what could be causing this.

More details please! What type of faucet? One handle or two? The brand name? How old is it? Come on back with all the information that you have, Tom

It's a small single tap. The brand is COBRA. Im not sure the exact age of the tap, but the house is about 15 years old and I can only presume the tap is just as old. On the piping leading to the tap, is a branch of to the toilet. When this is filling there is no noise.

When you hear the noise open the toilet lid and see if the sound isn't coming from the ballcock. Let me know, Tom

Hi Tom. The noise is not coming from the ballcock. The pipes are rumbling/vibrating. Im not sure if the ballcock is causing the vibrating as the only time the vibrating happens is if I open the cold water tap.

Where's the vibration the strongest when you put your hand on it. The ballcock or the faucet? Back to you, Tom

I suffered from vibrating pipes for about 3 years. They got so bad it would actually vibrate the whole 2000 sq ft house. After much reading on-line, one suggestion seemed like a good simple start. It was to replace the flushing mechanism in all the toilets. Since I was able to identify the area of the house that shook the most from the vibrating pipes, I replaced the guts of that toilet first. To my surprise the pipe vibrations went away immediately.

The logic is that the flushing mechanism may let air in, or have some other defect which sets off the vibration in the pipes. It certainly cured my problem.

I am posting this in hopes that it may help others.

Just to follow up, the vibration did not necessarily occur when flushing the toilet. It could occur when another faucet was turned on, or even randomly at night when nothing was running.
