ResMed Slimline tubing and leaks (check your tubes!)

I found a Resmed Slimline hose in my closet, still in the packaging, and hooked it up last night to a s9 series ResMed. While my main hose was drying.

Interestingly enough while watching the leak rate live it was almost 30l/m with the mask properly fit. I couldn't feel any air coming out of the tubing, but I took the tubing out and put a regular size tube in and the leak rate went down to 1-2l/m. SlimLine tubing must have a pinhole type leak or something somewhere along the way.

Did you change the hose diameter setting on the machine with each different hose?

Yes indeed. That's why I was surprised.

I had a bad hose a few years ago and thought my machine went wacky. It was a new hose too so I never expected it to be the problem.
