How do I flush my condensation line w/o co2 tank ? Thanks

Go to the outside end of the drain hose and hook up a wet vac or other hi suction .

Good advice from hcb. Usually a plugged condensate line doesn't require high pressure to clear. Even sucking or blowing on it will usually do the trick. Careful when sucking as you don't want to swallow a bunch of gunk. Or even just an air compressor with the right bit will work wonders.

Surely you Jest? But if you are 77 and have done that , OK. I think I'll pass that type of cleanout.
A wet vac is also good for cleaning out sink drains, stopped up commodes,and stray cats.

Not 77, just my screen name. Shopvac for plugged toilets, and sink drains. OK.

Look for a clean out right before the condensate trap.

I have never seen a trap on a drain line??
Every drain line I ever saw was not consumer friendly. I found "suck em out" saved sawing into and glue back.:)

I always install a clean out right before the p trap so that it is easy to clean. What do you mean you have never seen a trap in a drain line? If there was no trap to clog then there would be no use to clean the line.

we alway install a clean out right befor the p trap so that it is easy to clean. WHat do you mean you have never seen a trap in a drain line? If there was no trap to clog then there would be no use to clean the line.

True enough. I never been in a P trap. The original poster hasn't responded so we are spinning our wheels and not going anywhere. I think we are talking about draining the condensated water from a central air conditioning unit from the house. Am I confuzzidated?

Most drains on a-coils require a p-trap(per install instructions) to avoid air blowing out the drain, usually have a an open vent by way of tee.

Try using a wet vac attachment called the diyvac .Fits great on 2.5 inch wet vac hose and has a fitting on the other end to attach to your condensate line pipe outside .They are on eBay for $20+ or www.diyvac.com
