Dripping condensation (all over my floor)


I have dripping water from the joint where the PVC condensation drain connects to the body of the (indoor) HVAC unit. On the Carrier FV4CNF003 I have, that joint is just below the horizontal filter. See below for the close-up (not the stream of water) and the fuller image. Any thoughts?

cut drain - remove male adapter and make new drain and use teflon tape and or thread sealant when reinstalling.

The drain pipe may be clogged. The problem is you don't have an opening to clean the pipe. Needs to create one. the top of the P-trap will be a good spot to create an opening.

if you can access the other end of the drain (where it terminates) a shop vac can be used to suck out the clog.

Yup. Go outside and hopefully you can find where the condesate pipe drips out. Put a wet vac on it. You may want to put your hand there so you have 70 to 80% suction. Take the vac off as soon as it unclogs.

Thanks for all the suggestions. I did drill hole in the top of the elbow and put my fish tape down through to try to unclog it. It seemed to help, but I will check the progress today to make sure that it worked - the wet dry vac is also a great idea

This can cause issues as well with a pull-through air handler like yours. As others have said, replace the 90 directly on top of the trap with a tee, and then add a short piece of pipe on top of that Tee, and cap it off. This will allow the system to maintain the correct pressure on the drain system, and also provides you with a cleanout system for the future.

See the image below.

Lowes and probably other places sell the little blue chlorine or unblocking tabs to clear out gunk. My A/C guy for my office A/C's says you can put a cap fill of bleach in there for a cheaper solution too.

He actually is not crazy about wet vacs. This is why I said use your hand at the pipe to keep the vac from pulling 100% suction.

primary is clogged, as mentioned several times before

also if you don't like your floor getting wet (should it clog again), run the secondary drain somewhere (the 3/4 fnpt fitting directly to the left of where the PVC is coming out) where you will notice it, but won't care if it gets wet.

Or get a "EZ Trap" (google it). It will replace your current trap and provide a clean out T (as mentioned earlier) and it has a float switch to automatically turn off your a/c if it clogs. So if your A/C stops working, just go look at the trap (the EZ trap is clear, making it easy to identify clogs) and see your new present
