Simply placed the plastic grommet into the top of the pipe (see pic) and pressed the trigger. That aside, took me a couple tries to realize I wasn't getting a good seal, but once I did the A/C condensate drain line was utterly bone dry, with a small ugly pile of white algae on the ground next to the exhaust. I'll be a monkeys uncle, it actually worked as described!

Made no modifications to the drain line, like several friends suggested. ), got this fixed the same day I noticed it. I never have projects that finish without unexpected incidents occurring, but this one worked and finished in about 5 minutes!

I'll update this review when I get to use the item, but the recommended combo on the page was with the wrong cartridges, and there were several Q&A that said this takes unthreaded carts. Here's a picture - 12 gram is too small for the container and as you can see, its clearly threaded. Probably going to make this a regular maintenance thing, once in summer, once in winter (Orlando, FL).
