A bubble tester can be installed instead of a test point. They detect gas flow and provide a visual way of seeing if your gas system has a leak.

To ensure your LPG system is leak free there needs to be a means for testing it. There are two solutions:
1) Have a readily accessible approved test point in the pipework
2) Install a Bubble tester in the gas locker (which allows easy checking of the system at any time without the need for tools or equipment).
A bubble tester must be mounted in the gas locker, they are not allowed in the cabin.
