I have made a video of a leak from a Greenstar Heat Interface Unit:

https://drive.google.com/file/d/1jFRVAvcXaFRKC_wlNaf-zjAJy8uou5Ss/view


This is in the common room of our Council estate block. As you can see,
there's a kind of valve that is spitting rusty water and overflowing.

I reported this to the Council, but they said the engineer came and
couldn't find anything faulty.

I need to know what that thing is called and why it is leaking so that I
can go back to the Council and have the job done.

I have the same unit at home but I don't have that thing coming out of
the unit.

Thanks in advance.

Is the rusty thing made of metal?

could be a non-return valve can't really think why one should be needed
there, send the council your video and tell them to look closely for the
drip of water?

It does look like a version of a tundish on the outlet of the PRV: https://www.screwfix.com/p/mcalpine-tundish-19-23mm-x-19-23mm/5684v
(in theory clear plastic, but with added rusty grime)

It sounds like two problems. First the PRV shouldn't be opening to put
water here, second the piping around the tundish shouldn't be dripping.
The second might be because the overflow is blocked, but the first suggests overpressure which is a fault.

Without knowing the exact model it is difficult to diagnose. It looks
like a pipe under pressure from the fittings used.

I think Simon has the best suggestion. And ask why the engineer couldn't
find anything, despite there being an obvious leak?

Could you do another video looking upwards into the boiler, please. And
with a close up of the leaky bit.

^^ I meant interface, not boiler.

At the moment, my best guess is that the leaky bit is not part of the
heat interface at all. It's just been poked under the cover of the
interface for neatness.

It might well be an automatic air vent. In that case, a tiny bit of
water spitting out with the air may not matter much, and that might
explain why the engineer thought there was nothing wrong.

To put a new AAV on might involve draining a large part of the system,
so why bother?

I am not familiar with that type of boiler but looks to me as the outlet
for the pressure relief valve. Try and establish if that pipe simply goes
to the outside. If so it is the PRV outlet. If it is the PRV then it should not be spitting out as any water flowing through the pipe is not under pressure even if the pipe fitting is loose. It might be blocked somewhere
and as a result back filled with water.

Shouldn't the PRV pipework be copper, and not plastic, so close to the boiler? Or indeed any pipework?

My MPHW tank did this - tuned out to be a faulty pressure regulator.
Check the hot water pressure if you can - should be no more than 2 .5
bar or thereabouts.

Likely culprit if ion a hard water area is scale

I managed to replace mine OK, but its not for the faint hearted

Good point. Many boiler installation instruction require a minimum
length of copper from the flow side. However after checking for my
Intergas boiler I can't see any stipulation so seemingly not a universal requirement.

It is the condensate drain off. It looks like the fitting has come apart slightly. If the condensate tank wasnt full when it was checked by the
Council, then it is quite possible that it was running fine when it was checked, and no leak could be seen. These have a small tank inside the
boiler, the condensate comes out in one flow when the tank is full,
rather than constantly dribbling out like some boilers.
Its a simple procedure to take it apart and refit it correctly, and also
check the outlet pipe is clear, as, if that isnt clear, it will back up
and eventually turn off the boiler.
It looks like it needs a good clean, something that should be done on an
annual service, but one of the things that is easily ignored.

Usually due to a leaking valve on the filling loop, which legally should be removed after use, but never is.

There's a flexi hose in the video with a screwdriver isolation valve on the
end of it. The camera moves too fast for anything to be in focus but best I can
make out is the valve head is at 90 degrees to the pipe, ie the valve is
turned off.

It could be breaking the Water Regulations, but, if there is a check
valve on the loop, and another check valve on the incoming supply, then
it would be very hard for there to be any backflow, so almost impossible
to break the Water Regs. <https://www.legislation.gov.uk/uksi/1999/1148/schedule/2/paragraph/15/made>

That doesn’t fit with the OPs photos. Tun dishes aren’t fitted to condensate drains normally.

Condensate isn't normally coloured brown.

In the video the drips of water are clear. Could the brown discolour be

In a building such a tower of flats, there's a central boiler with hot
