Derek, you are an absolute diamond bloke for creating videos like this. I really appreciate all the videos you do and never give this up because you don't know how much you help people out with this. Top man.

Thank you Derick for all your hard work and sharing it with us on YouTube Also the free calculator and paperwork. Top job.

Awesome video and excellent breakdown 💯

One thing everyone I see on socials going through this don’t mention is that if you go over 23 mbar on your TT you must bring it back down between 7-10mb and bring it back upto 20-21mb. Also for purging if you have a imperial meter divide your m3 by 0.028 to find what cubic ft you need to purge

Awesome. I would do a tightness test regardless. Potential money left on the table.

Great presentation Tom 👍🏻

Thanks Derek - Just downloaded the sheet and got the App - Cheers mate. Very useful.

Great video derek as always, but must admit I don’t understand why gas safe want to make life more complicated it’s really put me off wanting to continue working with gas

What about pre paid meters when they run out , only have a boiler they just keep resetting boiler till it fires up?

How would you calculate on a imperial gas meter .

All your expensive books will need to be updated now as they're obsolete. Viper could send out some ammended pages, but that's too easy.

You sir are a absolute leg end

If g4 meter and pipe size less than 28mm or equal then for purge volume you dot need to multiply 1.5 then we have to purge 0.01meter cube .am I
Saying it correctly. Let me know pls thanks

How do you measure the perch volume if you are testing from an AE CV? Where there is no meter.

Question of the Day Tomkat

If I had 5 employees working for me under the gassafe inspections only one needs to be inspected does that also apply to British Gas
with hundreds of thousands of gas engineers working for them only one needs to come forward to pass the exam for all of British Gas engineers because the HSE requires so many per year to be inspected and it seems to me me they go for sole company I was inspected 2 years ago in a hotel now again it’s becoming a joke looks to me they are trying there best to get rid of sole traders

Hi Derek, when is the skills portal coming out?

Quick question. Previously we didn't have to disconnect appliances if the drop was within tge parameters allowed with no smell of gas. If we are now having to disconnect the appliances I'm assuming we have to commission appliances when re connecting ?

Question Derek.
If there is no cooker or hob where you can purge can you make a”Purge Point”on the pipework where you can fit say a one ring burner and temporarily attach it to the gas pipework and purge the pipework from that and of course cap off with a compression coupling at the end of it?
I hope that my question does not come across as daft.

Sounds like you need a divorce from this industry as you sound worn out and stressed.
