**Q: Should I be using these during the winter season when we are not using the air conditioner? Also, can this tablet fit in a 3/4 drain line?**
A: Hi B. Howard, 

Thank you for reaching out to us, and we appreciate your interest in HVAC Guys Flow Tabs. 

During winter, a Flow Tab would not be needed as when your system is in "heating" mode, there wouldn't be moisture dripping into the drain pan. However, when using your system in the summer in "cooling" mode, moisture in the air will condense on the cold coil and drip into the pan, which can cause mold/odors/slime to grow in your pan. This is where you would use the Flow Tabs. The Flow Tabs can fit a 3/4 inch line; for best results, you must place the tab on the drain pan, not inside the line.
For your reference, the Flow Tab 3 Ton is 1 inch in diameter and 1/2 inch in height.

We hope you find this answer helpful. If you have any other questions, do not hesitate to contact us directly —https://amzn.to/2Uw4SxW.

### ⭐⭐⭐⭐ Great product
*by K***D on October 12, 2025*

Im in my 70's and I cant crawl around an attic where my air handler is like I use to. So when I'm doing my pre summer PM of my three ton central air system I stack two of these tablets in my condensate pan and Im good for the summer, one and done! No more putting half dozen tablets in every few weeks. The only con to these tablets is they dont last as long as advertised like some other reviewers have said. Thats why I stack them, but even then they are still a great value, and the two tabs last all summer. Hvac Guys make other products that are better suited in my minisplit system as well. I've tried a lot of different products by other companies but Hvac Guys products have worked the best for both of my systems.
