literally just had this happen to me and had a plumber come clean the line. Took him maybe 30 minutes.
I do'nt think there's anythign you can do.
My a/c drain line had been getting periodically clogged, even though we routinely maintenance it every 6 months.
I put one of those cheap snakes through the line after removing the P-trap at the sink and all it did was push the clog further down the line, and actually made both my sinks start filling up from the A/C instead of just one of them.

You can try to run the snake yourself, but if that doesn't work, you'll need an industrial one from a plumber.

this sink is upstairs (subtle brag)...how long does the snake need to be? 25 feet seems sufficient but I know they have longer ones...

i knew it had to be there because it wouldn't drain..just a little further...just a little...


Inexperienced here. But I feel like my sink drains a lot slower than it has in the past 3 years (home is 4 years old).

How do you snake the kitchen sink if it has a disposal on it?

do what chicken did, unscrew the P trap underneath (with a pan to catch the water) and insert the snake into the pipe. even if you didn't have a garbage disposal you don't want to have to feed the snake around that U.

It didn't matter how long it was for me. All I was doing was pushing the clog further down the line. the one the plumber used actually broke the clog up and then it was flushed out.

Before I messed with the p-trap, the water would drain, albeit very slowly...whatever I did yesterday made it not drain at all.

Pretty common to do.

I think a 25 foot snake is plenty long enough.

You can buy a cheap roto rooter (25ft) at Home Depot and that might work. Lately, I’ve had more luck removing p trap, taping end of pipe shut with duct tape to create a good seal, an then poking a small hole in the duct tape. Then I power up the air compressor and put the tip in that small hole I’ve created. It usually destroys any downhole blockage.

Like I said, about the A/C line. Odds are the line is putting ice cold water into the line. The plug is right in the wall after the "p" trap. A quick run of a snake should break it lose. After all together, run a little drain cleaner.

That cold water will slow / stop the draining of the sink.

So, I bought a snake from the local hardware store...25 footer...I could only get it about three feet in before I got stuck...I think the pipes do a 90 degree turn down in the wall, goes down 15" and then does another 90 degree turn, so this cheap snake wasn't up for the task.

I put the p-trap back on and turn on the water, and it still filled up and stayed fill...

So I went back to the hardware store and bought a mini plunger and some heavy duty liquid clog remover. Those two things did the trick.

Thanks for all the advice!

Use that every now and then. It will keep you from fighting a clogged line.

I mean, this liquid clog remover started crackling and smoking as I poured it in...product is called FlowEasy...20 oz bottle. Dangerous stuff but works...

One of the most common ingredients in drain cleaners is sodium hydroxide, also known as lye.

The AC lines get algae build up usually in the Ptraps or anywhere water sits. That's why its recommended to pour bleach, vinegar, or another acid in there to kill it and break it up. The algae can build up strong enough to cause a complete blockage.

If its a sink blockage its usually some sort of combination of hair, crap you've dropped down, soap, etc. Mine are usually clogged with hair, hair products, and things like rubberbands for my kids hair.

I guess I will never know how much the snaking helped...but the combinations of limited snaking, mini plunger and liquid clog remover did the trick...about $65 in purchases...Plumber would have been $200+

Glad that did the trick.

My plumber usually just snakes it. Those chemicals heat up the pipes and can cause damage if used frequently.

i have the same thing, 2 AC drain in to daughters sink.

took a while but got it to drain by plunger and lid plumber on and off. But AC guy said the connection from the AC was all junked up, had a kink in it and was better to cut the pipe and put a new one on that fit better.

Cost me to flush the lines and happy he didn't charge me to refit the connector correctly.

Ive learned now to put drano in all drains every few months.

They make some pretty bad stuff called clobber you might be able to buy from a wholesale supply house. IDK if your state requires you to have a plumbing license or not. Just note its basically acid though so open a window and give it time to air out or you'll get sick. That will typically clean out some pretty nasty stuff. Now that you've got it unclogged i would suggest running that quarterly or even a heavy duty retail drain cleaner just for maintenance.

If you already have used the basic snake then try these steps.

1. Fish a hose down the vent pipe and turn the water on, make sure someone is inside and tells you if water starts back filling into your sink so you can turn the hose off. 2.Fish a hose and cleaning bladder down the vent pipe and try to flush it out with some higher pressure. 3.Close up your vent stack with some tape, and then hook up a shop vac to your wall opening where the drain line enters the sheetrock. Try to vacuum and/or blow the clog out. 4. Call a plumber.

My plumber uses "Thrift". It definitely works in a hurry.
