Tribune HE PRV 3/6 bar to 3/8 bar

[GT200]

My tundish was permanently dripping from my Tribune HE 150L indirect cylinder and plumber concluded it was the multibloc PRV which was a 3/6 bar. He couldn't find a direct replacement at his supplier and put a 3 bar/8 bar on.
I'm now worried this could be setting me up for future problems and maybe a big safety issue....any thoughts please?

He's lazy and incompetent...the correct expansion relief valve is 6 bar and readilly available from many specialist suppliers. Typically £15 to £20 plus del.

The dripping valve is normally due to insufficient air charge in the vessel but can be down to several other reasons.

Get him back and also check he's G3 licensed..he'll have card but it's almost a worthless qualification.

 

[GT200]

So is there a safety issue here? I need to prove a point to him. He's a difficult individual and I regret engaging him.

 

[GT200]

I will check the G3

 

[GT200]

Btw he charged me £200 for the part. Said it was an old part/configuration so difficult to source and said the 8 bar 3 bar was the replacement according to his supplier (probably 25 years since installation now)

Even the whole inlet set is rarely more than £50.
The control inlet set for older cylinders often becomes obsolete but the cylinder manufacturer will have alternatives. Whilst an 8 bar expansion relief is normal for some cylinder makes I can find no reference to the Tribune ever having anything but a 6 valve.
Confirm with the cylinder manufacturer/soecific unvented spares merchants.

Unfortunately Kingspan, the original cylinder manufacturer no longer offer support. As far as I can understand they don't own the cylinder side anymore. The support people I spoke to just weren't interested.

AFAIK Kingspan just buy in and rebadge the cylinder and now that Range are in administration offer no support.

[GT200]

I've now spoken to the plumbers merchant And then there supplier who agreed they'd supplied the wrong part to the local merchant. My plumbers ever so eloquent response has been "well I ain't cocked up"...I'd have said as he's the engineer then he's the technical authority on this.
Haven't paid him yet so we'll see.

 

[Gasguru]

Have you asked to see his G3 card?

 

[GT200]

He hasn't been back as yet.

Get him to whatsapp a pic of it...illegal to work on unventeds without it.
