Nu-Calgon 4296-60 Pan-Treat Scum 200 Tablets

Drop two tablets into the P-trap of your air conditioning condensate drain every 6 weeks during air conditioning season and let them disolve. Work great! You’ll never have a drain plug with algae.

My house was 5 years old when I bought and it always had condensation overflow. I tried everything to drain, clear, and clean the issue. But it continually happens. I accepted my fate and the fact that the evaporator was not leveled properly during installation. So I placed 2 large plastic tubs underneath to contain the output. Then having to check and dump the tubs religiously. I also tried cleaning the coils with the foam spray to no avail.Not having much hope, I gave these tablets a try. It is a game changer. After the first round with 2 tablets on each side of the drip pan in the groove next to each coil, the issue cleared up magically. So now I just have to put in 2 new tablets every month.Hope someone with the same issue will find this review and use this product to save yourself the trouble and costly AC tech visits.

They work to keep the drain clean

Have used these for two seasons and well worth the money and time.

These tabs really work, fixed our issue after the drain line backed up and we needed to clean the coils. Get a package of these tabs and one of those connector hoses for your shop vac to properly clear the line and you’ll never need to pay for a service call again for routine maintenance.

I always have an issue with my drainpan backing up because of clogs in the drain line. My HVAC company came for my semi annual maintenance and offered to put their tabs in for $75. I showed him what I had and he said it's the same thing they use. They only put in 4-5 tabs so the price savings are enormous when you consider you get 200 tabs in this bottle. If the pro's use it then it's good enough for me! Great value.

works very well keeping drain clear

These tablets have are easy to use and last for almost a month. Keeps the pan and pump clear and clean.
