Noisy Megaflo - I think

[Unregistered]

Out of the blue recently we are experiencing an odd vibration from or near our Megaflo Cylinder. The noise occurs when toilets are refilling after flushing (doesn't matter which one) or when the washing machine/dishwasher is taking water. It appears to be coming from either the cylinder itself or the pipework near it, and only occurs when cold water is being taken. Everything else appears normal. We have tried recharging the air gap, and draining the house of cold water, but the problem still occurs.
Any ideas please?

Thanks

What I would advise is you will need a G3 qualified plumber to work on it as the Megaflow is unvented and must have a yearly service anyhow to keep it working properly and more importantly, safe.
