Unvented system with no tun dish fitted

[Jack Sorng]

Hi,
I recently spent £1550 getting a RM Stelaflow tank installed as the plumber told me I required it for the mixer shower I was having put in to an extension. Subsequently the plumbing out of the tank developed a leak and as I was unable to get hold of the original plumber I contacted a different one. He had a look and told me the type of tank installed meant it has to be notified to building regs, which it hasn't as well as the fact that no tundish was fitted making it potentially unsafe. I have been unable to get hold of the original plumber and can see myself having to spend a lot of money putting right the work and getting a building regs reference. At the time I didn't know about these requirements and greatly doubt he was G3 qualified.
Has anyone any experience of this and subsequent outcomes?
Thanks in advance

Think you'll have to bite the bullet and get a G3 guy in to look at it and make it safe. Yes you may have to pay but your safety's more important

you just 'dont ' leave a tundish off, it comes with the cylinder. I doubt it but may have left something else off. I agree with Riley, just get a proper guy in to check it over

I had a cracker few weeks ago. I was called out to a job with an unvented tank which was relieving itself from the prv . Seemingly this had been going for years since it was fitted. As soon as I looked at it I noticed there was no expansion vessel to cope with expansion .. very dangerous senario . The guys just lucky his pressure relief was working properly. Very lucky.

I had one very similar Kris only difference, there was an expansion vessel just on the wrong side of the combination valve!!

Even if your not G3 how can you get it wrong when it is drawn as an idiots guid in the instructions!?

A tundish is not the most dangerous of things to omit. It is an air break in the discharge pipe, plus a visible check on the relief valves going for some fault, or just to see if they stop passing water.
Completely against regs though & incredible that anyone would not bother with instructions.
To the OP, - I personally would get the unit all checked out and replumbed if needed. Following up on the guy that done the botch is secondary in importance, but would be good to teach him a lesson, as he has perhaps continued to install more unvented both badly and without qualifications.

"but would be good to teach him a lesson, as he has perhaps continued to install more unvented both badly and without qualifications."

I've seen bad but I'd be more worried by "dangerous"

The top and bottom with unvented is that if you follow the mi's you cant go wrong. Its all in there. No excuse for not being g3 qualified, just lazy barstewards.

Hope you get it sorted at not the leg of cost... tundish visibility, always the first thing on my mind then is hope in finding the safe discharge termination without having to make good afterwards

Sadly, I think this issue will rear its head on an ever increasing basis.

Perhaps a large scale clamp down combined with a national awareness campaign will improve things. With the current tight budgets in the public sector I can't really see this becoming a priority anytime soon.

I hope your situation is sorted soon and the original 'plumber' is taken to book.
