Shortlived rejoicing. Zilmet was vibrating again the next day. At least it's not as often as previously. Will ask plumber to return. Original plumber had probably not installed correctly, hence no noises, but also had loss of pressure and component failures - he came with my 'expert' builder...

. Good point. Spared the background detail earlier. Had an overflow leak initially. Plumber diagnosed failed Zilmet and then the failed pressure reducing valve. Both replaced for new. Only had the noise since then. Have let out a tiny amount of air from the Zilmet - no more noise!

. Thanks Dan.

Hi. I have a Stelflow duplex unvented cylinder, with Zilmet expansion tank. When I turn on a tap or shower, the Zilmet tank emits a loud noise, and vibrates. It has been recently replaced and charged correctly at that time by a good plumber. Anyone know why this noise may occur?
