remember seeing my dad do similar when he fitted a wall heater back in late 70's . . . I wasn't old enough to question why . . . .

When it was town gas that was the approved method, it had a much lower flame speed

There is no meter fitted that's why i need to adapt to test, i would never fiddle a meter, im more of a politician in life so i get someone else to pay the gas bill
Testing without a meter is an invalid test, the volume of the meter defines the test period

It isn't
Hmmm I do plenty of houses on lpg that have no meter, never had a problem doing an air test, or a purge.

Thats why it needs a 5 minute stabilisation period on lpg
If you do houses with lpg you must know on nat gas a tightness test is based on meter size and pipe volume?
Luckily for me my last ACS expires in 2 years, that will be 25 years as a gas engineer over. Cant bloody wait

This is what you want
I was issued with this a very long time ago If you are desperate I can post it for you to use but there is probably an easier way to test using a rubber bung and nipple. When the meter goes back in they will test it again properly.

I would be more concerned what the OP is going to use to test it and at what pressure, appliances fitted, who's been messing with the pipes to warrant thinking there may be an issue.
There are reasons houses go bang.

I hate lpg, I have the lot (except commercial catering)
But I do live in an area with lots of caravans, so needs must

Yes its new pipe work but it runs under a floor i want to finish off and not have to worry about any issues, I think the problem is sorted after raiding my mates van and looking through some of my old fittings boxes where i had random stuff from over 30 years back, i found a brass fitting with the correct thread to go into the gas out connection and the hole up the middle of it is a good fit for a brass 15mm elbow that was for brazed oxygen lines.. the result
I picked up a test kit as mentioned by @gaz1 so should be good to try.

15mm str, Yorkshire manual air vent and screw a test point in

Reading this…Ive never messed with domestic gas or felt the need to. But have done loads and loads of both pressure and leak testing of complex systems upto 600 bar.
looking at the test kit, and reading this, including the bit about the damaged meter, do they never use an over pressure relief or protection such as a bursting disc to prevent damage due to mistakes?

Low pressure gas is 75mb absolute max, no need for any protection, a fart has more pressure
Medium pressure is 2 bar, that has various over pressure shut of valves both in the regulator and in the external pipework, plus a vent pipe for absolute worst case

i saw it all the time as an app. gas board always used to check there joints with a lighter
Retired in '76 I think at the age of 60. Went on another 37 years till 2013 and died at the age of 97.
He set light to a gas holder repairing it once.... story went that they had to drop the gas and lower the portion alight into the water that sealed the sections. Pressure inside kept the flame coming out rather than in. Noone I know with any real details of that is still alive now but I think it really happened.

At Chalford, near us the water board connected the high pressure main to the gas main by mistake, that put out any fires …….. and boilers, cookers as well. No-one had gas for quite a while, all had to be drained, cleaned out & dried. It was a good few years ago, but I bet the foreman was in trouble!
