Alde bubble tester

[Miker]

I've just installed a new gas bottle box system and have realised that I didn't put the sachet of liquid in the bubble tester. I assume that it does not come already filled.
I have no instructions for the tester and would welcome advice on how I fill it with liquid. The red top goes up and down, but I've no idea why. Also the glass bottom looks as though it might unscrew but I'm reluctant to fiddle with it blindly and, perhaps, break it.

Yes, the glass bottom (it's some sort of clear plastic on mine) does unscrew. it's a 10 second job (as long as its accessible)! Just unscrew it and pour some liquid in.

The glass bottom unscrews and you fill it with the liquid to between the moulded lines (on mine anyway). Then when you turn the gas on at the bottle you hold the red top down, which diverts the supply through the liquid, and watch for bubbles (there shouldn't be any if the gas is off at the cooker and there are no leaks).

Thanks. Which way is the thread on the bottle? Do I turn it clockwise looking from the top to unscrew?

It's a clear plastic moulding with a small ridge as a turning handle. It's a normal thread so turn it anti-clockwise looking at the handle end. This will release the clear plastic cup which you need to fill up to the mark.

testing...

the procedure for a correct test is: switch on but do not light all gas rings, in other words the flame failure device is the only thing stopping the flow of gas. turn on at the bottle and allow a few seconds for pressure to equalise throughout. then press the red cap. at most one or two bubbles may appear then they will stop.

it is most important never to press the red cap when any device is burning as the gas frow will blast all the liquid out of the tester.

Re: testing...

Thanks again. Now you tell me about not pressing the red cap whilst the gas is burning! I'd better check that I have some liquid still in. Luckily I bought a spare sachet.
I think that the plastic bottle was fastened by a gorilla. I had to get some pliers on it which I was loathe to do.
There was a gas leak in my pipe work, ironically where I had cut the pipe to fit the gas detector, and hadn't done the nut up tight enough.

Re: testing...

not tightening enough is the standard amateur mistake (me included). when tightening a compression joint, do up hand tight then give half a turn with a wrench to bed the olive in. that's a lot more than 'seems' right.

Checking for leaks

The bubble tester spotted the leak in the outward nut, but I'm now wondering about the nut on the inward side. I could buy some gas leak spray from BES but the postage will be more than the can. I'm wondering whether old fashioned soapy water would do the trick. It used to work no bicycle innertubes!
