Let me tell you, this little blue cartridge has been a game-changer for my Florida home. After years of panicked wet-vac sessions whenever my AC drain gurgled, the iFLO system feels like cheating at home maintenance.

The magic happens every two weeks - I actually hear a faint 'glug' from the drain pipe when it dispenses its bio-enzymatic cocktail. No more that disgusting black zooglea snot clogging my lines. My husband (who still can't figure out how to replace the cartridge) jokes it's like having a tiny HVAC butler.

Pro tip: Wear gloves during cartridge changes! Learned that the hard way when some solution splashed on my wrist - tingled for days like I'd brushed against poison ivy. But seeing chunks of dissolved gunk wash out my exterior drain line? Totally worth it.

After eight months, I've only needed one emergency wet-vac session (during garage renovations). Compared to my old quarterly $200 service calls, that's a win. The app could be smarter about manual dispense mode, but watching it auto-order refills before I even notice we're running low? That's the future I signed up for.
