Incorrect installation by British Gas - What to do?

Razor900 · 9 Feb 2016

Nope the boiler would've been shipped with an orange plastic cap blocking the expansion vessel connection. I would say the OP is probably right and there's been air trapped in a couple of the rads.

Will be interesting to see how you get on as constantly running at higher than expected pressure won't have done the tupperware boiler any favours

Sounds like BG engineer has left his extension hose for charging the vessel on the vessel TBH Let's see if I am right.

That looks very much like the pipe I saw - it was attached to EV but the other end just hanging in the air.

Just read your other thread and the PRV isn't leaking.
Sounds like you have a system leak as if expansion vessel was faulty the PRV would be dripping.

You are right - neither PRV, nor EV are the only problems and there is a leak in the CH systems (most likely pipes) that we will deal with (re-pipe).
However, The PRV is certainly leaking cos I collect 0.2 - 0.6 liters of water everyday from the PR pipe outside, and the pressure rises to 3 bar every time the boiler is working, m-suggesting the EV isn't doing its job ( not connected anywhere as found today) So PRV and EV has to be dealt with anyway and I feel they have to be fixed first, right??

I bled all the radiators a few days ago, so there should be no air.

Hope not. We reduced the usage to 4 hours a day.

I'm not afraid to confess that I have made this mistake once before. (Forgetting to remove the cap and connect the ev hose).

Fortunately I noticed when I was commissioning the boiler.

But it is an easy mistake to make if you get distracted whilst connecting the boiler to the frame

It just stroke me - how could the EV have been incorrectly installed (not connected) if the second engineer*) who came a week ago said the EV pressure was toll low ~0.5 bar and he managed to re-pressurise it to 1 bar? If EV were disconnected, would he managed to re-pressurise it at all??

Could it be that EV got disconnected itself due to the incorrect boiler operation (faulty prv, e.g.)?? Please explain.

*) in total we have 3 visits form the insurer over the last couple of weeks, every time a different guy.

Yes

You would get very wet if it did

Thank you for explaining

I also think that the BG engineer left an air connecter as pictured on the EXV.

The Worcs I saw yesterday had a braded permanently fitted connection between boiler and EXV.

I am never sure if some of these engineers making wild claims are totally incompetent or have learnt to totally bamboozle customers by quoting nonsense.

A new boiler should be serviced at the end of the first year to validate the warranty.

Yes and they should offer re-compense for the inconvenience caused, and provide an apology for the hazard created should the pressure relief valve have failed to operate.

Perhaps a free holiday too? Pay the mortgage for a year? No questions asked bunk up with the BG Chairmans missus?

Have you claimed your PPI yet, Bernard?

Most smaller Worcesters (i's until last year, iJuniors, Si's, Compacts) over the last 10 yrs have the expansion vessel on the backplate, separate from the boiler. You have to connect one to the other during the installation process.

Tony I fitted well over 500 Juniors and I can tell you they forgot to connect up the expansion vessel that's what the orange plug was. We've all done it at some point. If there was enough air in the system he wouldn't have noticed.

Just because it's something you haven't come across don't automatically slate the guy that attended you make yourself look like someone making wild claims whose totally incompetent or have learnt to totally bamboozle customers by quoting nonsense.

Thanku razor i agree re the plug i dont do worcesters but i have been shown this, and ur right i got warned by the mods, but agile calls out everyone because punters no no difference that he is one of the least experienced engineers and due to his age when he qualified may never reach expetienced status, his pompous post boiler ny ****

BG can and do very occasionally leave the EXV disconnected. Obviously it's an over sight by the fitter but certainly it happens.

I've come across a few, some have caused issues like the OP has. Some I've caught before it was noticed and discreetly fitted it correctly.

How dare you question the experience and expertise of one of the best gas engineers in the UK.
Shame on you Bunny...I realise he came into the industry late in his life but even so.....

Love how certain PROs on here are saying no way this cant happen .
Its not an unusual fault and perhaps its caused by same sort of fitters who say no way this can happen.
We attended one that had been in for 3 years BG were a bit stand offish at first till gas safe arranged a joint visit then they got it sorted , customers wall was soaking from constantly repressurising the system after prv discharging.
