Just noticed we had an lpg leak last night, so I've turned off both our 45kg cylinders. We use gas for stove top and hot water.

The leak became apparent when the bottle selector switched over to the other bottle.

I'm not sure why it has occurred, if it was damaged with the bottle change or what?

Photos to follow. Just wondering if someone can tell me the replacement part. The fault is in the end of the hose that screws into the bottle. I swapped the bottles over and the fault moved to the new bottle so it's a problem with the hose connector not the bottle.

Gas leaking from where the screw in thread is. Haven't had time to have a good look for debri in the connection but seemed ok when had a quick look earlier.

Pigtail plug sounds iffy, I'd call a gasfitter in to look/replace. It shouldn't be too bad $$$ wise as pigtails aren't super pricey





Most problems are the result of previous solutions...

Also does my bottle switcher function correctly.

This is the situation.

Left bottle full
Right bottle empty
Dial of automatic switcher pointing to left bottle.

Have a leak at the right empty bottle with the faulty pigtail.

Use soapy spray to be 100% sure where the leak is coming from.

 

But from your picture and arrow marks, it appears from the connection into the 45kg cylinder.

 

Then that would be a simple case of replacing the O-rings which are either perished or missing. When you screw the connection out, there is one on the end. Would pay to replace both connection O-rings. Left and right.

 

If in doubt, best bet to consult a gas fitter...

Turn off the gas, disconnect the hose. The O ring on the end of the pigtail will be damaged or missing.

Check that the pigtails are nice and flexible. If not, get a gasfitter to replace them.

I know where the leak was as when I put the bad connector on the filled bottle it's a really strong fast leak.

Are the bottle guys supposed to check there is no leak when they connect the bottles because the leak was really obvious and loud and blowing really hard.

The only problem I have had has been with the spring ball valve thingy at the end of the screw thread on pigtail. The bit that goes into gas bottle.

 

I would disconnect the pigtail from the right/empty bottle - Is gas leaking from the end of pigtail?

 

Is the ball valve on tip stuck in/open or is it protruding/sealed. - Could be some crap or condensate holding it open?

 

Not a gas tech or anything, just things i have had to check before. 

 

Good Luck

I had mine changed recently about 2-3 months ago, ask a gas fitter to change pigtails.
The old pigtails been using for more than 10 year plus, the gas fitter said its wear & tear & old.
Even just one of the pigtails leak so decided to just change both so don't have to deal with the other one in the future.

 

It such a simple thing to do, get it connect and use soapy spray at the end & make sure no more leaks.
Since that's what the gas fitter do when he changed the old ones out. Too bad can't DIY.

How quickly is the gas regulator selector supposed to change from red to green when you change bottle?

Only just got home now.

The o ring looks ok and the pig tail looks identical to the not leaking one. Have our plumber coming over Tuesday/Wednesday to check it over +- replacement.
