A few years back I bought on clearance at BigW one of those mushroom looking outdoor gas heaters.
During operation a few family members believed they could smell gas.
I did the soapy water trick - but never found any bubbling.

Then the other night when I had it operating, again, people could smell gas.
This time I pulled it completely apart and did the soapy trick, and yes, I found a significant leak at the site indicated on the regulator. There was a bonding agent on the thread that had perished (got worse with time?) and tightening the joint didn't help.

The heater really requires the gas hose to enter the stem at 90 degrees to the gas outlet.
I couldn't find anywhere in town that sold this type of regulator. Trade stores, camping supplies and not even Barbecues Galore.
Went to Bunnings. I'm not a big online shopper.
Impressive Gasmate accessories display.
Very helpful Bunnings staff member served me.
We found the regulator I required with the appropriate new hose whose kit provided the correct sized threaded connections.
Easily fitted.
Better that the original fittings/hose
No leaks.
So, just a post to say thanks to Bunnings and to a very helpful team member! 🙂
