HVAC GUYS – Flow Treat Tabs - 200 Tablets | AC Drain Line Cleaner | Prevents Odors, Keeps HVAC Drain Pan Clean, Prevents Overflow | One Tablet Lasts up to 4 Weeks

Work great. Used to have problems with algae buildup that clogged the drain lines and caused a weird smell. These cleared it up really quickly and have prevented it from happening again. Also really easy to use. Just drop one tablet so it lands in the drain pan every so often and you have nothing to worry about.

I've been using these tablets in my condensate pump for several months now, and they've worked great. Since adding them, I haven't had any issues with mildew or sludge building up in the pump or the discharge line. It's been a simple way to keep the system clean and running smoothly. Definitely a product I'll keep using.

I was having an issue with my drip pan clogging, ever since I bought these I have had zero issues with gunk building up. Just toss two or three tablets in occasionally and forget about it for a month or two. Very good quality and last you awhile! Water flows perfectly now and easy to use! 200 tablets will last you a long time!

These tabs are a bit smaller than the pvc tube so you end up using more than a different brand. They are doing the job and keeping the algae buildup at bay.

Works as advertised. Fast shipping
