Urgent Central Heating System Pressure Problem

[Nigel B]

To be honest, so are we...

Would you mind giving me an idea as to what the obvious problems are?

I cant get back far enough from the cupboard to take a decent photo with everything shown - perhaps there are some other items not shown in my photos?

You've got a fairly important safety valve missing that would cut off the primary flow in the event of the cylinder temperature overshooting its setpoint.

There's other issues but that's the main one.

When was the last time the cylinder was serviced?

 

[lame plumber]

if it is a split coil, which it may not be then you need at least 2 other bits replace/installed urgently to make things work safely again, which are manufacturers parts. These need installing by a qualified (G3 regulated) plumber. If the coil is split then a new cyl is needed anyhow and the completed cyl inc safety devices will be installed by the plumber. Because of the risks involved in doing it wrong, this site wont offer the actual answers as folk may be tempted to give it a go themselves with poor results.

Not wishing to scare you, but this is the result of all the safety devices failing on an unvented cyl, yours is missing one of them out of the 3 normally installed.

your cyl should not do this,but it needs some safety device fitting as if your other 2 failed that video is a reality should things go wrong. Hence why our advice isnt forth coming and why you should get someone in to rectify the problem

[lame plumber]

Good man, thank you Nigel.

It's the safety of you and your family we're concerned about. And thankfully you're listening. There's too many that don't.

[stevetheplumber]

[Nigel B]

Can anyone recommend a good G3 certified plumber in the Yeovil, Somerset sort of area that might be able to help me?

Is that a coke bottle cut in half to make a tundish?! Or is it just my eyes?!

Don't get that set up. plus it looks like the D2 isn't upsized but it could be the pic. Then there's another pic with a standard tundish?? I can't be looking hard enough
