Condensate Pump Installation - Don't Miss this CRITICAL Step!

- As a home inspector the most common condensate pump installation error I see is that the overflow switch is not wired into the air conditioner or furnace. In this video I explain how installers get away without doing this step and why it's a problem. I also explain how to connect the condensate pump overflow switch properly.

Watched so many videos, finally this guy gave a straight answer to what to do with those crazy blue wires ... and how pump works with or without commection, and how to connect, all in short video! Awesome.
Hello, I am so very glad that you made this video called, " Condensate Pump Installation-Don't Miss this CRITICAL Step! I started to purchase a vintage home on August 8th, 2019, that had a propane furnace. This was the first time ever experienced a propane furnace on my own. Have had two years of a problemed furnace and thermostat. The furnace when it did turn on, did work really good, except for having to constantly keep turning the thermostat on. Had a furnace man repair it twice. So this year I thought that I would not use the standard fiber furnace filters and bought a custom-fit window screen to allow more airflow and to make it easier for the furnace to operate and it's made a difference, for sure. Several days ago, had put clean water into the condensation pump and it started right away. Then today noticed it had overflowed onto the mortar floor. So I thought that perhaps it was the floater that had to be cleaned and so I took apart the condensation pump to find out if the floater was stuck and it seemed to be alright. I had wondered why the long wire on the pump had never been attached to something. So today is when I discovered your video and to my surprise, you had the answer. So I have followed your directions. I dis-attached the thermostat wire from the "R" position, connected one pimp wire to the "R" position and attached the second pump wire to the thermostat wire and taped electrical tape on both ends, then connected the tubes to the pump and plugged in the pump, turned the switch on the furnace and it came on right away. I hope that the pump starts when it gets full enough to start it. I will let you know when I have discovered if the pump turns on. The thermostat wire must be working fine because the furnace did come on right away. So thanks again for making this video.
I scoured the internet to find this simple information. Thank you so much!
Wonderful video, probably saved my basement God bless you for serving mankind like this
I'm about 10 videos in and yours is the only one that showed me how to wire it properly. No more blown fuses yay!!
One of the best videos ever made
Just another thing, You should splice an inline fuse off the Red wire. This way you dont have any transformer issues down the road.. just another tip..
Great video! 3 or 5amp inline fuse
I have looked high and low for a video to show me how to install the low voltage wiring with no success, finally I have found you. You have no idea how much I appreciate you. Thank you my friend. May God bless you.
My pump died and the wires were not hooked up.I am lucky that it is in the room off the garage and thanks to your video i am going to hook up the wires.Thanks
Thanks Martin, straightforward and to the point, very informative.
Incredibly helpful tip. I’ve been living without a pump and using a bucket to collect the water simply because I had no place to plug it in. I will be getting one this weekend and trying this out. Thanks!
Very clear instructions that helped me greatly. Thank you! The old pump I just replaced was connected to yellow and blue going to the G/C on the board.
Very critical...awesome video. detailed in the right areas.
Great tutoring thank you.
The furnace installers hooked up the condensate pump, but didn't wire the overflow switch, so I had to do that myself. I also have the condensate pump plugged into a GFCI outlet with a trip alarm for an extra precaution.
Thank you!
Happened to me I lost power to pump went downstairs there was water everywhere I bought new asurity n it came with shut off wires I need to install to thermostat good video
have a brand new furnace only a year old. i got lucky that i went in my attic to check my attic windows it gets freezing temp up there. saw ice on my pump and water on my floor. must of happened that day. the people who isntalled it never hooked up this off switch. its unreal that they wouldnt do that and your furnace keeps going as your pump is overloading and spilling all overthe floor. this should be mandatory. or they should at least warn you.
my pump says, COM RUN and a hole that says TSTAT , does R go to com or run?
Do you have a picture diagram of how it looks because my power source is wired directly to the unit and I’m not sure where to run the overflow lines to. I just installed a diversitech pump and it provided the lines but my old unit didn’t have them so I don’t know what to do with them.
If my video didn't provide the answer you need, do some more online research or hire an HVAC professional.
Most newer furnaces measure the pressure to the condensate trap. If the pressure gets too high due to any plug or over flow it will shut the furnace down
my goodman furnace a year old def did not. in fact there was so much water in the pump it was leaking out of the seems of the top cap that clips on to the bottom tank. the installers didnt simply hook up the wire to the pump to shut the furance off
Is there a specific reason to put the overflow switch in-line with the R wire on the thermostat? Could you wire the alarm in-line with something like the furnace's cabinet door switch?
DANGER!!! There is a HUGE difference between the two wiring locations you mention. The thermostat wires (R, W, G, etc.) run on 24v. They won't hurt you if you touch them. The cabinet door switch is120V and can carry 15 or 20 amps of current. TOUCHING THE DOOR SWITCH WIRES CAN KILL YOU!! Also, the wire that runs to the overflow switch inside the condensate pump is small and can't handle the load that the door switch caries. Never rely on my advice or information alone. Do your own research and hire a professional to do the work for you. You're better safe than sorry!
@@HouseKnowHow Thank you. I really appreciate the info. I'll check and then use the thermostat R wire.
So if you wire the overflow that way and a pump stops mid winter you won’t have heat, so this should be case by case
Why would a pump stop working in the middle of winter if your not running the ac?
Lots of times I am gone for days at a time Which is better water on floor or frozen pipes?
I guess it depends on what the floor is. And, I'd try to avoid both! I'm sure there are digital thermostats that would communicate with an app on your phone. They could likely tell you if the temperature in the home was not above a certain threshold, or that the furnace isn't working. I know there are thermometers that will do that. Then, you can have something set up with a local contractor that can go check on the home while you're gone if you get a notice of a low temperature.
It’s called breaking hot, awesome stuff though
You can do same principle with yellow wire. Thats your condenser coils/ outside unit
Remember that the AC and the high efficiency furnace both produce condensate. You need your overflow switch to turn the furnace off for both heating and Cooling.
I am for the first time installing a furnace/Air Conditioner. I would never NOT wire it properly. I am surprised that people are willing to gamble with their homes and potentially their lives!
I’m curious, if the pump is hardwired into the unit, rather than being plugged into an outlet, is this step still necessary?
Yes he mentions that. One wire gets wire nutted to the red already in the space and than you land the other wire from the pump and land it on red.
My furnace doesn't have an R anywhere on it
It does it probably wired with another color wire
@@BernardBethea6339 Thank you sir
MISS ANOTHER STEP.... Elevate the pump (e.g., put it on a brick that's easily removed) so that you can lower the pump below the drainage pipes that go into the pump. This way, you can easily remove the pump for maintenance and cleaning.
That's a good one! Sometimes they're plumbed so that you can't get them out.
Thanks. I’m sorry, totally off topic, but does anyone ever tell you that Stephen Colbert is your twin?
