Excellent video. I like the uncluttered explanation to the point. Also describing all the options allows us viewers to make decisions for the different scenarios. Thanks.

I got stuck in an attic 7p.m. on a Friday in AZ because NO One explained this to me properly. I eventually figured it out. I also see the pure logic in the correct way to do it. Thank you sir!

[@bruderbro907]

Thank you for making this! Just exactly the info needed. 😎

[@elgkas9928]

Another great video. You keep hitting them out of the park!

I try

[@briancarlisi2224]

Excellent video with well explained wiring! I personally always break red as I want the T-stat to go blank whereby the customer will call so we can clean out the condensate line, both in summer & winter, particularly during deep freezes when the condensation line exiting the structure can freeze backing up the condensation.

Great work, Mike. Thank you.

Very welcome

Perfect. Thank you.

Good stuff

[@karellfernandez73]

Thanks again.

[@wim0104]

awesome! thank you.

[@JerseyMikeHVAC]

You're welcome

I just saw a video that breaking Y would cause the fan to stay on squirting the water everywhere

[@JerseyMikeHVAC]

If the fan is blowing water everywhere the float switch probably isn't installed correctly.

I have a question and I'm not smart when it comes to this stuff, but I can figure some stuff out. lol I have a Daikin Fit. The company who installed it gave me a really cheap condensate pump. The pump has built in safety switch wires so not hard to figure out where they go to as they are the same. The one I'm looking at getting to replace it has 2 wires and 3 clip spots for it. Alarm (which I assume is for an external alarm), Run and Common. I'm trying to figure out which wire goes where. The float switch I have has 1 wire that goes to a wire nut where the condensate pump is tied into. The other wire from the switch goes to a wire nut then up into the air handler. I dont know how its tied into the board itself. So does the run wire go to the float switch wire or does the common?

[@JerseyMikeHVAC]

What's the model of the condensate pump you're looking at?

[@thedude2897]

@JerseyMikeHVAC IQP-120 ClearVue. I actually had that pump on my older unit for years, but the company who put the new system in took it out and didnt even ask if I wanted to keep it.

[@JerseyMikeHVAC]

@thedude2897 You should be able to disconnect the 2 wires connecting to the current condensate pump and reconnect them either way to common and run on the new pump.
That said, if you want to hook up an external alarm you may need to reconfigure some wiring, because that pump was designed to cut off the cooling wire returning from the thermostat and not all installers install it that way. But for just the safety switch alone the easy two wire switch is all that's needed.

[@thedude2897]

@@JerseyMikeHVAC So the common and run wires don't matter which goes to the switch and air handler? I can just wire them whichever way? I won't bother with an alarm.

[@JerseyMikeHVAC]

@thedude2897 it shouldn't matter

Thanks again for this info. I see on U TUBE, that a guy used a EPOXY WELD TO SEAL A LEAK ON A R410A HEAT PUMP system, on the hi side. Is this a good thing to do? And do you know if STAY BRIITE #8 will hold, on an ALREADY SOLDERED JOINT that is leaking, on the high side? I have a leak on my heat pump system, and the joint where the hi press. switch is soldered is leaking. I am thinking of just expoxing it and add some freon and see if that will fix it.

[@JerseyMikeHVAC]

There is an HVAC specific epoxy called Devcon Special F that could work, though I've never used it so can't attest to how well it works. It's expensive, but I wouldn't use any other type of epoxy because of permeability (even if it holds physically).
