Hi,
I’ve recently had my external expansion vessel changed on my Telford Tempest stainless unvented cylinder as water was leaking out the PRV which showed up to be a split diaphragm on the old vessel.
Now, the new vessel appears to be doing its job (no water leaking out the PRV anymore) but I am now faced with a new problem. When drawing hot water (usually for the first time after it has been heated) there is an almighty rumble/grown that doesn’t sound too dissimilar to a tuba/fog horn! It only lasts about 10-15 seconds but as I live in a block of flats, I’d imagine it wakes/disturbs most of my neighbours as it’s pretty darn loud (and scared the poop out of me when it first did it!)
Would anyone have any idea what could potentially be causing this? It must be linked to the new vessel being fitted but it was a like for like swap..
To give you some idea of what it’s doing, I’ve posted up a video on youtube which you can find here: http://www.youtube.com/watch?v=xiRZnUuNmJQ
Cheers,
Ben
