I have never in over 15 years of HVAC service seen or heard of a pee trap on a secondary drain

I’m more confused than when the video started 🤷🏻‍♂️💯‼️⁉️👌

I dont understand how I know LESS after watching this

I enjoy the tips but when your snaking gum loud enough to come through the video I had turn to another, please remedy this for until then I will not share your video

Vent and trap primary drain always put a float switch in the secondary drain. Best way to do it. Primary clogs up secondary switch will shut down the unit. Simple as that. Never have a flood or drain pan overflowing. Always trap and vent your primary drain though. That vent will allow it to drain in any situation as long as your air handler is higher than the fall of the drain.TRAP AND VENT GUYS.

Good job omitting describing the difference between negative and positive systems so that the home owner understands the difference. I figured it out on my own. Hopefully most others will also. 👍

Dude ......loose the gum......good vid otherwise

So you're telling me the company that installed mine and used a piece of a garden hose didn't do it correctly?

Also another thing not to do is chew gum while speaking for a video.

This doesn't make sense with the secondary drain. There shouldn't ever be any water in the secondary drain line unless the primary is clogged. So if the primary is working properly then how would the secondary ever form an airtight seal? There won't be any water in that p-trap

The best explanation of condensate traps on all of youtube thank you

I like this guy. I'd call you. It seems whoever installed mine had no idea what they were doing. Now I'm fixing it!

You touched it last, so you own it. Thank you sir

The first thing that I would consider is to trap unit #2 with a vent on the exiting side of the trap. Depending on the fall between unit #1 and #2 will determine the application. Pressure equal on both drains equals proper draining. Hope this helps.

Now I have an older furnace. It appears to only have 1 drain, and I noticed the drain dumped into my crawl space. Well I just put a new encapsulation in, so now it's dumping into a plastic. Should I go though the hassle of putting a P trap in? It's a vertical application, I have no documentation on my system, and the condenser is under the blower. And it blows air down. I was thinking of just running a line to my sump pump.

Good job, very clear, thank you Sir!

My installer did not add a J trap on the secondary drain and it appears my primary drain was not used at all and all the condensate was draining through secondary drain. I added J trap on the secondary drain as per your video and I can see that condensate is draining through my primary drain now but I am still getting some condensate through my secondary drain. How do you make it go away? Is it something to do with the height of shorter leg on the Strap on the primary and secondary drain. If they are kept at the same height then that can behave the same and condensate can drain through either line. Water level difference is only few mm higher on the secondary drain as compared to the primary drain. Thanks for your feedback.

The PVC lines for the drain are lower on that model pan which I'm glad they changed/updated, I've seen several where the PVC line is 1/4 inch above the pan causing standing water and mold in the large surface area pans, most of those I've seen mounted in attics that are humid anyway. This pan looks much better.

Does the access hole in the drain line have to be plugged it t left open

Thanks for this. My ac unit leaking water one drip at a time. I'll have to keep working on it.
