The pipe that my ac condensation goes to keeps over filling if the AC is on for a certain amount of time. I assume it is clogged, can I just use a liquid to clean this, thanks.

Hi Steve,
In my area we run our AC condensate lines out of 3/4" PVC and terminate them outside the house to drip on the ground. AC condensate lines grow a kind of jelly in them and stop up. When that happens we clear the line out by shooting compressed air through the line and then closing off the end, filling the line up with bleach and letting it set for a few hours and then blowing it out again. Hope this helps with your problem. Good luck, Tom

Best thing is to blast it out with air if you can. Might try a garden hose. The liquids might work. Poking a wire down it may do it too. Once open, pour some bleach down it to kill the yuck that builds up. If it necks down from 3/4 ID to 1/2, and has very many elbows, reroute it with 3/4'' all the way and as few of elbows as possible.

I've cleared the flex drain line before by sticking the end of it in the end of a small shop vac and sealing around it with my hand while the vac does it's thing. Works pretty good... I've heard of using a small amount of bleach in the little sump resovoir to kill that gunk too.
