Checking for D.C. Air leaks.

I have a new laguna c|flux 1.5 for one machine at a time. I've plumber ABS 4" pipe on the ceiling with blast gates. The D.C. Is connected with a 10' flex hose so I can pull it out for maintenance. It's a lot of hose for normal use and drops straight off the D.C. Before doing a 170 degree turn back up to the ceiling.

The abs goes immediately into a wye. All other turns are long 45s.longest distance to a blast gate is 25 feet. Shortest is 10 feet.

CFM feels weak though I am getting most of it.

Are there easy tests for leaks at the friction fit points? I have not used tape or caulk.

Is that flex hose bend at the start a giant problem? Should I shorten the hose and add a quick disconnect for maintenance? Other suggestions? I'd rather not jump to the 6" pipe everywhere right away please.

I suspect your duct work is the biggest drawback, but I check for leaks with a smoke stick (a cigar, in my case) and watch carefully. I suppose you could use a feather or something else as well. Just hold whatever it is next to the seams and watch the flow of air. The cigar isn't the best probably, but i had one on hand. Did take a while to air the shop out.
