I checked and surprisingly nothing seems to be leaking. Is there anything wrong with this set up, especially the part with the two metal hose clamps.

I recently noticed my primary AC Condensate drain was very clogged. In tracing it down with one of those pinhole waterproof cameras I found that its clogged for a good 7 feet in a section that goes from the attic to the master bathroom sink drain. It is in a section that is not easy to blow with pressure or suck with a wet vac and I can't quite find the source of it because it seems to be somewhere near the sink drain in the master bath but my camera can't take the 90 degree turn from the wall to under the sink. From under the sink there are too many 90 degree turns for the camera to follow as well. I have dried Drano into the access port - which I later read is probably really bad. I let it sit for a day and then tried vinegar which I later read is not as bad but may not be recommended. The drain does not seem fully clogged as it does allow some water through because during the day it does not overflow into the secondary drain until the end of the day. Presumably when the AC does not run as much at night it is able to catch up and when I check it first thing in the morning, the clog has usually gone down anywhere from 1-3 feet. I have also tried getting it from the sink side with vinegar and baking soda through the sink drain. Time to let a professional handle it or are there any other tips/tricks for this? To give an idea of how the pipes are laid out, there is a primary drain for the AC condensate line with an access port about 1 foot away, it makes a 90 degree left turn from there and goes about 4 feet to another access port where it makes a 90 degree turn down the master bathroom's wall. It then makes a 90 degree turn under the sink with 2 more 90 degree turns to the drain which is just upstream of the p trap for the sink drain. First time poster and recently just started getting involved in some home repair so do not hesitate to correct any of my terminology!
