Clogged HVAC condensate drain line. Installing a Rectorseal Model SS2 overflow shut-off switch. 

Am I the only one who screamed "Nooo!!!" at the computer screen when he said he was going to cut out the tab on the secondary outlet? Came here for the comments and didn't see any about it. Glad you left it alone. 😂

I liked the way you explain every single thing and the way you films and do the job , because I am immigrants to US and my English is not perfect,, But your way of explaining I'd excellent .. Thank you

Hope things are operating properly for you. Just came across your video and would suggest you replace your 90 degree elbow above the trap where the humidifier drain goes down to your a/c drain with a T-fitting and have an 8 inch stand pipe installed and left open so you allow air flow for the drain to run freely. If there is no air gap left then the water draining could and probably will always backup and continue giving you problems. With the open pipe you can always pour some white vinegar into the pipe to help keep the mold from building up. Take care.

Excellent explanation! I've been curious for a while about how to wire one of these OF switches on my Goodman unit and now I know. Thank you!

Good job I am happy you uosed your common sense Good thing you didn't break the overflow

This is the only video that really show how to connect this SS2, thanks.

Thanks for your help!

GREAT Video. I'm also in Georgia and having Drain Line issues This Year. After viewing a few videos, I can share that Your Video is exactly what I needed to see. Thanks again for all that you do.

Good job!

I think everyone will agree that having an access panel to the evaporator is a really nice feature. This should be standard on furnace/ac combos where oftentimes the only way to see/clean the ac evap is through a whole-house humidifier (remove filter) or to cut a hole in the ductwork. 😢

You need a inlet that allows you to pour white vinegar into this drain line a couple of times a year. That will keep mold from building up in your lines. I also have a spray foamed home and live in Alabama. Had my issues with moisture. Installed a whole house dehumidifier about 7 years ago. It helps tremendously during the winter! I use my upstairs HVAC as a dehumidifier in the summer time. Since it's a 1.5 ton unit. I allow it to do most of the work during summer months. It keeps the house comfortable during the day. If the temp is set right on your upstairs unit. The dehumidifier will be unnecessary during the hotter months of the year. I also have those Goodman units. 😂 Definitely had problems over the years. Most HVAC professionals will tell you, they are fairly simple to replace parts on and overall cheaper to repair than the more complex systems.

That is your secondary drain ,which the plastic is part of the pan to put the water level higher which makes it the secondary

Do you think you would've had all the ventilation issues with the spray foam if you only used foam in the attic and basement then used regular fiberglass insulation on ext walls?

Haha RU-vid certified. I had to have qualified a long time ago. I want my certificate!

BTW 78° isn't hot .. but, I'm sure it's hotter in the attic..

You don't want to tighten it too much because it can cause the pan to crack. You should have kept the SS2 a little loose to the point where you can actually turn in slightly. The tape will make sure it doesn't leak. Plus if water does get into the switch; to avoid vacuuming it you can just twist is down and empty it. Certified

The AC drain line SHOULD BE easy to Clean Out when Properly installed 👍😅. When NOT installed Correctly then it's a Mess 😕😔

Also u must have enough fall to supercede the water column of the return . In layman terms the ahu has a negative pressure, if u have 2 inches of negative pressure w.c. u must have that much fall before the p trap. It's not all cut and dry .I've seen contractors make the same mistakes. If they only would not he proud and read the Manuel and code book they would be ahead of future problems. I'm not a Eisenstein, just a old mechanical contractor that god has lead through the years of a fantastic trade.

You know, I was gonna start this out by saying some derogatory comments regarding your meandering about spray foam. But, then I guess you're pretty smart for using the internet to fix your home on the cheap. Good job. I'm sure that you've convinced some manufacturers to hook you up or monetize this video. Btw, what is your average power bill? Did you G.C. your own home?

I think my favorite idea from RU-vid is put a cutoff valve above your u trap and install a Waterhose connector befor the u with a cutoff valve so you can just connect a water hose and send it

I don't know if it was said or now. But instead of taking anything apart, and you knew where the drain exited the house, You should of gone there, rapped a wet drag around the pipe to get max suction from your shop-vac, and sucked the clog out there. Heck of a lot faster, easier, and cleaner, since I bet you'll be doing this quite a bit until everything's tunes in.

Is teflon tape really needed on plastic fittings?

By putting the switch in the R wire you will kill both cooling and heating, In the heating mode you are not going condensate, but I can't tell you if there is a better place to put on a heat pump. I'd have to look at the wiring diagram to figure it out.

Do not knock that out you will be in trouble

You had your tool up there. use tape and vacuum it out. No need for water unless youre cleaning the coil. LEAVE THAT THERE. It's the secondary hence why its blocked off a bit.

It's the 2ndary over flow drain , code requires. The secondary to run out over a widow to alert owner that main drain is clogged. A flag for the inspector. Better safe than sorry. Mechanical contractor since 1980. A proper drain means a lot u don't want the water to overflow into the ahu then to the emergency drain pan.u wNt the overflow to come out the factory secondary drain then to the em drain out out over window.

Another thing I forgot to say was i would go with closed cell foam instead of open cell. Open cell foam does not have a vapor barrier closed cell does

I want a filter door like he has can I get it aftermarket for a Goodman

Need to eliminate those unions. Come off the unit with a new p trap and clean out tee

went to my attic and i see bats

Pulling air from above at the humidifier.

Interesting … you’d think (or, I’d think … ) a float switch would be part of the system already. I’m learning that’s not the case. My attic unit leaks, and the pan beneath it overflows. Now I’m considering a 2nd float switch, that kind you have in the line and and a pan switch at the bottom … because water coming downstairs is a really bad day. Maybe just wire the pan switch to an alarm that says, “Hey moron, turn off the A/C now!!”

Did the compressor stop running when you lifted up the float?????

Noooooo don’t knock off that eyebrow on inside the secondary !

Do you have open or closed cell sprayfoam in your home? I seen your other video about your opinion on sprayfoam I disagree. Look up build tight ventilate right if you having problems with being uncomfortable in your home it should be the hvac guys fault for not ventilating your home properly

Why is there no condensate pump?

Should be a running trap. Just call the installer boss and send him a bill of $8000.00 and he will fix the situation immediately.

Leave it in there

What a waste of time! Next time it plugs up just use a shop vac on the outside drain. This is a very common problem with mini splits. It’s a good idea to make this a spring cleaning chore every year. That overflow should be knocked out and the wires should go in between the red wire to the thermostat

Put bleach in the pipe monthly bud!

Dude. Leave you air handler alone and call a professional. You will be doing yourself a big favor.
