    Cleaning condensate pipes without applying pressure

    After finding unglued condensate pipes, and at other locations having to cut lines, I came up with this way of cleaning.
    After capping the vent-

    1. Take a 3/4"PVC tee and attach a foot of 3/4"pipe to one leg.
    2. Cut the other leg off at the TEE so it looks like an ELL with a hole in the side.
    3. Connect the base of the TEE to the end of the condensate line outside.
    4. Stick the end of an air gun with a 2" brass or copper tube screwed in place of the tip (since the tube is soft, no fancy threading is needed unless you want to build a tool) into the cut leg of the TEE.
    5. Wrap a rag around the opening between the gun tube and the tee to make a seal (this is the suction side).
    6. Apply air (or CO2, or nitrogen) pressure and the condensate and gunk is sucked from the pan and piping.

    Remember to uncap the vent since you are so excited by how easy this was, and the cool blast of water, and gunk which is now all over the side of the house.

    Yes, if you use a long enough brass tube you don't have to cut the tee.
    Yes, you could make a tool to do this.
    Yes, it won't work if you cannot find the end of the condensate drain.

    No, I don't have any pictures because I make one when I need one.

    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    I can't picture what you're trying to describe. Especially adding air co2 or nitrogen, when the title said "without applying pressure."

    Eric1589,
    The pressure is going out into the world, not up into the drain. I'm sorry that I was not clear. Cheers!

    I'm having some serious problems with your procedure. As per step #1, I've attached some PVC pipe to one of my legs. So far so good. But in step #2, you want me to cut off my other leg. Sorry dude, I just can't drink that Kool-Aid.
