So it seems common that people try to get away with screwing bigger than 2 inch. I will find out when the last alterations were done. Yes tamz i am green on this but really want to get into it so i really appreciate tips off u guys. I am picking up quite a bit of commercial work, more than i expected since doing my change over. I think it is vital for my company. I have all related british standards and igem documents printed out.

Sorry forgot to say, is there still a risk of the slam shut valve going off even if im only testing from the meter outlet? How should i prevent it?

I think people who dont know what they are doing or cant weld will try and do it an easier way.
You can use 4" stainless steel mapress for gas, must get gas fittings though.

I thought mapress was only upto 54mm and under a certain pressure ?

You can use copper Mapress with gas fittings up to 54mm
Stainless steel up to 108mm
Not sure if it has pressure limitations, I only do low pressure work.
