If your home has a central air conditioning system, you may have noticed the AC drain line outside.
This pipe is located near the air conditioner’s condenser unit and it often drips water on the ground, so it’s hard to miss.
If you’ve ever wondered what’s with all the dripping, well, the drain line moves condensation from the inside air handler to the outside.
If this line clogs — and when it does, it’s usually because of algae — it can cause all kinds of problems. Like major water damage inside the house.
You can prevent a clog with simple, routine maintenance. Just pour a cup of household bleach into the AC drain line from the inside.
But once a clog forms, you can’t rely on the bleach method to do much of anything. So, attach a wet-dry vacuum to the drain line outside. (Remove the vacuum’s paper filter first.)
Then, turn on the wet-dry vacuum and suck the clog out of the pipe.
