Combine a cup of water with a spoon of dish soap to create your propane leak testing solution.
What you need to make your solution to check for propane leaks?
Now keep it in the cup, and bring it to the connection you intend to test!
Pour a very small solution over the propane connection/fitting your testing and watch for bubbles!
If there is a leak, it will create some pretty obvious bubbles and show you exactly where it’s coming from! Make sure to wiggle things a bit to be doubly sure that there is no leak at any angle!
Our leak was actually at the fitting outside of the camper, and it only leaked at certain angles. But it was there, and leaking quite a bit when it did!
