I suppose you've also fitted non-return valves to the cold feeds to your 1000 cylinder installs?
If you've installed 1000 cylinders, you should be asking yourself why this hasn't been diagnosed. As indicated earlier, by fitting a NRV to the cold feed, the expansion that takes place in the cylinder as the hot water heats up cannot go anywhere but up through the vent. The fact that you couldn't answer my simple question at the first attempt begs the question do you really know what's happening?
I'm sorry to sound harsh, but this is basic Level 2 Plumbing, it ain't rocket science. I don't care how many years experience you claim to have, but personally, I'd be embarrassed to claim to be a professional and ask such a question.
If you think my ideas are inadequate for your 30years of experience then I apologise, but as all pro's would appreciate, they are only ideas until your physically stood in front of the job.
Good luck pal!
