Unusual gas main connection pipe size?

 Two engineers have visited my house so far to fit a smart gas meter but they dont have the correct  fitting, nor an adaptor, to connect to the gas tap. It doesnt seem there is anything we can do about it!
The size of the short copper pipe coming out of the flange and going into the lead pipe is 0.795 inch / 20mm outside diameter. 

The house is 1962 but the gas meter is 1994. I’m suprised that it is so unusal. Anyone know about gas pipe sizes?

Sorry, the fitting on the ecv into the reg itself is an approved fitting, I should have been more clear. There is no current approved fitting to use on these.

 

You can contact your gas transporter to request a change, you can find out your gas transporter here: https://findmygdn.co.uk/

 

I hope this helps :-)

Hi @paulmmmm,

 

I’m sorry to hear that you’re still having trouble with this.

 

It may be worth contacting Cadent again and explaining that you’ve spoken to an OVO engineer who has advised that there is no current approved fitting to use on these types of ECVs.

 

Please keep us updated.

Ok, so I went back to Cadent Connections Help and basically said this:

“I have been advised by an Ovo engineer that:   ‘Sorry, the fitting on the ecv into the reg itself is an approved fitting, I should have been more clear. There is no current approved fitting to use on these.’

Could you please advise the exact type of adaptor required so that I can make sure that  they have the right parts next time they visit.”

 

And they  (Connections Help) replied -

“I have passed this onto our General Enquiry team to request further information regarding the adapters.”

And they  (WeCare@cadent gas)  said-

“The adaptor that is required should be provided by your Gas Supplier through their Meter Equipment Management team.  Cadent are unable to advise on the type of adaptor required as they are the Gas Suppliers responsibility and you would need to contact them for that information.”
 

 

SO thats the end of it as far as I am concerned. No smart gas meter for me. What a sad story the whole smart meter fiasco is!

I have to say that to my eyes that looks like a lead pipe from the ECV to the regulator.

Would approaching this apparent stalemate as being a safety issue possibly prompt Cadent to get their fingers out and change the ECV so that it can accept an anaconda?

I realise that would probably entail engineers from Cadent and OVO attending at the same time.

Yes it is a lead pipe which of course wouldnt be permitted today. I suppose that would not in itself be unsafe. Not like if it was water.
I dont really see why an adaptor cannot be fitted to take the the taper ecv into 3/4” or whatever.

Hi @paulmmmm,

 

This all seems very frustrating.

 

Maybe Nukecad is onto something here. 

 

@Lukepeniket_OVO, just wondering if you’re able to give any further advice with this?

its now about a year since I couldnt get a smart meter fitted due to a problem with the connection size.

I now have a brand new pipe coming into the house right up to the meter. Now its gotta be possible to get a smart meter.
So I log on and I try to book an appointment - but NO!

Sorry, we can't install a smart meter

We are currently unable to offer you a smart meter installation appointment. Check back soon to see if we can book you in.”

It's probably still showing the block that was imposed fot the old piping. ie. The computer doesn't know/hasn't been told that it's no longer a problem.

Getting that kind of block flag removed can be a trial.

 ​@Lukepeniket_OVO  may be able to help shorten that process?

@paulmmmm good morning,

 

I’m glad to hear the necessary work has been done, and you can now have a smart meter installed.

 

@Nukecad is right - the previous abort / cancellation will mean that appointments are blocked. If you get in contact with our Support Team they’ll be able to get this unblocked for you. I’d recommend taking a photo of the meter and surrounding area and emailing it to hello@ovoenergy, explaining that you’ve now had the prep work done to have the smart meter installed. 

 

 

When you take the photo, please also post it in the Forum, as ​@Lukepeniket_OVO has been tagged here, he’ll be able to have a look at the photo as well and, as ​@Nukecad says, potentially expedite things. This is a simple one for Customer Services to resolve for you though, it just takes a few days for the appointment to be unblocked as it needs to be assessed by the relevant team. I might be able to get the process sped up myself for you as well if it’s delayed for any reason.

 

Once the appointment is unblocked you’ll be able to book the exchange via your online account. The appointment is free of charge - you just book your chosen date and four-hour window. Please note, someone over the age of 18 must be present for the duration of the appointment. You can find lots of handy smart meter guides in our Forum Library, and a guide for booking the appointment online here:

 

 

Hope this helps, cheers.

 So here is my nice shiny meter connection connection. The change was not instigated by me, all gas pipes in the street have been replaced by Cadent. I was impressed by how quickly they were able to do the job with minimal disruption. 
I’ve emailed hello@ovo. Thanks guys on the forum for your advice.

Hey ​@paulmmmm,

 

Wow, this is really impressive! 😊 I’ll tag ​@Nukecad so he can jump in and check it out, since he’s been involved in this thread before. If you have any more questions, feel free to reach out anytime.
