This video saved me a ton of money and troubleshooting. My house is set up just like this. I was trying to unclog the drain from the line by the condenser. Turns out my clog was right when I removed the rubber hose from the drain under the sink. Thanks so much!!
This helped me big time. The clog was right where you said it was under the sink. Thank you.
Thank you very much for sharing. You are the only who showed me where my primary drains. My HVAC guy cut the water sprinkler wiring on the outside thinking it was the primary, and no idea where it was. Now, I know!
I'm glad to hear this helped you out
THANKS! This fixed me right up! Saved me a lot of time and money!
This has been a great help towards my troubleshooting process
*Heavy when full*Excellent !! Made mywife very happy !!
Thanks so much! It worked awesome. Saved me so much money.
I'm 6'6", lift weights, weigh 245lbs ,any I'm pretty strong, but getting that rubber hose off kicked by butt. Anyways I got it done. Great video. Thanks.
I’m dealing with this right now lol
Try twisting it while gently pulling on the hose. Hope that helps
Any tip getting it off? Its kicking my butt as well
Thank you for your very helpful video. God bless you, Bro .
Glad it helped
Great video!!! Thank you!!!!
Great video. I finally found one where the drain line terminates into a sink instead of outside. I don’t know if that’s according to my building code requirements
Thanks you for this. This worked! I have the same setup.
Many thanks. I better understand what's going on now in my house.
Thank you for posting this video!
BROTHER! You saved me a service fee and a charge of abou 200-300 for ac tech to come out! Where do you want that check mailed to? lol
LOL, just share this with your friends 🤛. Seriously though, I'm glad to hear when my videos actually help.
thank you!!! that was my problem.
Thanks so much, exactly what was wrong!
The Primary AC line was clogged. This happens over time as dirt and dust move off the coil with condensation and into the drain line. Over time it builds up and develops a blockage.
Great video thanks so much for uploading it.
Any tip on how to get the black rubber hose off? My is sewn shut
@@Tvo281 yeah they can really be stuck on there if you haven't taken them off in a while. You could try taking the drain assembly apart by loosening the lock nuts where it connects to the p-trap and the bottom of the sink
@@HowitsdoneHandyman That's exactly what I did. It was still difficult to get off but I managed to find a clamp in my garage that helped me hold the hose in place while I rotated the middle part of the P trap
I have one of those black hoses under our kids sink directly below the attic where the evaporator coil is and another black hose under the master sink. I’m guessing the black hose under the kids sink is the primary drain line???
I,m guessing you have two units or one of the black hoses is abandoned. It's also possible that one of the black hoses is connected to the water heater pan.
@@HowitsdoneHandyman I cleared them both out just in case! Great video!!!
If your bathroom sink has a slow flow (most likely need to clean/change aerator) does this have an effect on the blockage or does the blockage in the primary line cause the sink to have a slow flow?
@@Tvo281 your primary line would be connected to the sink drain, not supply. So it wouldn't have an impact on the flow from the faucet. Hope this is helpful
@@HowitsdoneHandyman Thank you!
Is it normal to see small droplets falling from secondary or none at all?
you shouldn't be seeing any at all. That's a sign the primary drain is blocked.
How do I find the leak If the filter in the furnace is damp when I changed it last night and it's usually dry and not damp but it's usually dry any advice
If the filter is in the furnace I'm guessing you have a vertical furnace and the filter is underneath. If that's the case your primary drain is probably clogged and the overflow from that is making the filter damp. I would recommend opening up the access panel to the coil and see if there is water in the bottom of the unit. If so you need to clear the drain line. the steps in this video should help with that. If not it's likely more involved than I can get into here and you may need to call someone out.
Hope this helps.
Thanks

Having a hard time loosening the drain line to the P-Trap. Any suggestions?
You could try using a screwdriver to help pry the hose free of the barbs. If it's been on there a while they can really be stubborn.
What happens if I don’t have a P-trap in any bathroom, where could the main line drain to?
Honestly, your best bet is going to be to follow the line in the attic and work your way from there. There's any number of places it could go. I've seen people run them to plumbing vent lines and some run straight down the wall where it's inaccessible.
I did exactly what you said, but water still coming to the outside. What is wrong?
It will likely take time for all the water in the secondary pan to clear. If the secondary pan in the attic is dry you shouldn't see any drip. You could also leave the primary drain under the sink disconnected and feeding into a bucket to confirm it's draining properly. If it's not, you may have a blockage too large for the shop vac to clear. If that's the case, I would recommend calling an HVAC professional. A large blockage can happen if the unit is deteriorating internally and flakes of rust break off and get lodged against the pipe. An HVAC professional can advise you if this is the case and the steps to take to prolong the life of your unit.
Could a clog in the AC drain cause for back flow in my sink?
no, but if the clog is further down the sink drain it's possible the ac condensation could be backing up in the sink. but that would require you to clear the main sink driain.
Why u don’t show picture when u hook up the shop vac to the pipe u show under the sink, so crazy.?!
So that drain pipe above your window is your primary or secondary drain pipe? Also i noticed your drip pan was dry. My drain pipe above my window is leaking water also and my drip pan has water in it. What does this mean? I tried blowing through the pipe that is next to the drip pan to unclog any debris. It temporarily fixed the issue but every few weeks it happens again. Im a new homeowner and all this is new to me. What should i do?
The line dripping in front of the window is the secondary. The primary is the insulated line at 0.22 seconds. Blowing in the line typically doesn't work because it just pushes the blockage back in the unit and will eventually clog again. depending on your setup you may need to block off the vent on the primary to properly clear it. The drip pan under the unit is the secondary drain pan and shouldn't have water in it. If there's water there there's a problem.
@@HowitsdoneHandymanThat problem you are referring to is that the primary line most likely is clogged and that I may have to perform what you did in your video?
@@Tvo281 That's correct!
@@HowitsdoneHandyman How long did you run the shop vac for?
@@Tvo281 It varies depending on how long the line is and how much is backed up in the unit. Normally the clog is cleared within the first few seconds but you want to collect the remaining water in the line so it doesn't get all over. 30 sec to 1 minute should work under most situations.
Should you turn ac off first?
It really doesn't matter if the AC is on or not. either way, the primary drain pan is going to be full of water.
Is it normal to feel cool air coming through that pipe?
you really shouldn't but it's possible if you don't have a p trap before the vent pipe.
Who do I call for this? Plumber or a/c guy?
Wow. That’s a really dumb place to drain an air conditioner. Where I live that would not be code at all.
