I have a combi boiler: Chaffoteaux Minima MX2.
A few days ago water started leaking from the PRV.
It was leaking from the seat and from the side where
the discharge pipe is connected via a 15mm tap connector.
The tap connector is not 90 degrees and looks like its had
the end hacked off. It has then been connected to some orange
vacuum hose which in turn is connected to some more copper that exits
the wall outside.


I notice that there is a lot of play where the PRV connects; a slight nudge
and water will leak.
It is held in place by a 'hair clip' but there is movement in all directions: vertical, horizontal
and rotational.


Is a fitting with this much play water tight and should the discharge
pipe not be all copper? If it is all copper does this not add stress to,
what appears to be, a very flimsy connection. There doesn't seem to be room
anywhere to add a pipe support on the wall if/when the discharge pipe run is corrected.


A new PRV is all plastic. Whereas the old brass fitting had a red cap that had
a rotation arrow on it and a spring inside that was activated to release
water pressure. I can't see how the new one works. The red cap is
fixed solid.


What's the correct method for installing a discharge pipe run and why such a loose PRV
fitting?
Any help/comments gratefully received.

Thanks.
 
I think a picture is needed... I can't wait to see the orange vacuum hose... :smile5:

Pictures forthcoming.
According to Chaffoteaux tech support the boiler installation kit provides the spigot and some tubing to connect to the discharge pipe. Would you advise running it all in copper anyway?
 
I took a Chaffoteaux out of a caravan on Friday that had a clear plastic pipe coming from the PRV. I assume this was something that was done just because it was in a van. Perhaps it was a standard thing on them. I've still got the old boiler on my scrap pile, I'll have a look at the connection.
