Unvented Cylinder noise when hot water demand
Anonymous user 15/03/2024 - 2.55 PM
Hi, I’ve got an unvented cylinder and over the last few days it’s started making really loud noises when there’s a hot water demand, For example I turn the bath tap, and for around 30 seconds there’s a loud, humming or even the sound a drill makes, coming from the cupboard, and then it just stops and works as normal. It seems to be getting louder and lasting for longer. Any ideas what this could be? Thanks.

Hi Mattywolves
You will definitely need a G3 registered Plumber.
If you have Megaflo then the air pocket within the cylinder need periodically recharging....all you need is to discharge water from pressure relief valve into tundish until the gargling of water finishes.
If you have other Hot water cylinder then there could be other possibilities as well like sediment buildup or the water pressure is very high.

Yes to check the cylinder for faults you will require a G3 registered plumber but on many occasions I have found the problem to be s faulty fill valve in the toilet which causes water hammer
