Hi all, Just out of interest how does the leak sealer work, and why and how does it not seal the air pressure relief?
 
Ummmmmm that's a really good question dam it got me thinking now :(
 
It reacts with atmospheric pressure. When it's circulating and detects a small leak with air present, then it reacts with the air to form a membrane to seal the leak. It only seals small leaks. Larger leaks need you guys.
