Used it to test my new build for any leaks before filling loop with liquid... every single time it failed !!! After 1 week of fighting ( new fittings, tubing extensive testing of each component for over a week ) I decided to test leak tester ;) and guess what !!!! IT'S FAULTY !!!! So before you test your loop - check leak tester first !!!
Does the job
Decent price and does what it is supposed to do. Barrow offer good gear at a good price.
Barrow leak tester
Done the job just fine, one little nit-pick though is I wish they'd had the silicone connecting tube have rotary fittings, just to make it easier screwing in and out of items you're testing.
