Otherwise you could never get most pumps to work. As they always told us in school, water always flows down hill, but sometimes air pressure can exert a stronger force on the water than does gravity. You would think that the level drop going to the main line in the street (about 15 feet) would be enough to assure proper drainage but a vent is still necessary. There is a vent line that will vent the drains to the atmosphere. The plumbers have just been hooking up the floor drains in my new garage before they pour the concrete. At our house we have a construction project going on. As an experiment you could provide a vent line so see if that would help.

If that's the case you should feel a flow of air INTO the condensate drain line when it's disconnected from the drain line. You could have a suction problem with the air pressure inside the evaporator much lower than ambient. It's hard to imagine how you could have a problem like you describe. (He also said that an old rubber (furnco ? ) fitting could also cause this.)ДЄny thoughts anyone might have would be greatly appreciated.

Even though there is plenty of room for water to drip out while my finger is in the top section of the pipe, no water comes out!ДЄs soon as I removed my finger a large amount of water comes out.ДЄ neighbor said I need to install a pipe that allows air to flow out of the drain line between the drain pan and the P-trap, (or J trap.) I could believe this but how come I never needed this before? However, I noticed that my little finger closes about 60% of the opening the drain pipe. Just for kicks, I put my pinky finger in the hole to feel around for problems and found none. I observed the drainning water for a few more minutes and checked the drain pan with a flashlight and determined that there appeared to be no obstruction in the drain pan. I then disconnected the rubber fitting from the drain pan and a large amount of water came spilling out. I re-connected the pipe and guess what - No water dripped out of the emergency t-fitting even after several minutes. During this time I left the A/C unit on and observed a steady drip of water out of the pan.

I then snaked the 8 inches of line between my emergency Drain T-fitting and the rubber fitting connecting the PVC pipe to the outlet for the drain pan and found no obstruction. Well then, I unscrewed the plug in the T-fitting (which is well below the lowest level on the drain pan,) and no water drips out. I have back flushed the line and confirmed that it isn't clogged and I have blown through it and can confirm that there is no clog.ДЄfter the last clog, (last year,) I installed an T junction pipe with a screw-off fitting about 8 inches from the unit so I could easily drain it in an emergency. Water will not drain out of the unit when anything is connected to the drain pan outlet pipe.

I am having an unusual problem with the drain line on my Central A/C (evaporator unit) inside my home.
