Rated 4.7 out of 5 by 23 reviewers.
Rated 4.0 out of 5.0 by Excellent value pump with good features. I decided to buy this pump after I found the condensate from our A/C unit coming up from under the floor slab. I cut the drain pipe and directed it to a bucket for a while. An HVAC technician came out and looked at it. He recommended putting a condensate pump in which he would be happy to do for a few hundred dollars. I thought that was a great idea and knew I could do it myself. I looked around at various HVAC suppliers, but finally found this one on for a way better price. I found this pump to be a great value and I liked the features it came with, especially the high level switch. The pump is of all plastic construction, however it seems to be high quality. It pumps out all the water in just a couple of seconds, which I found surprising the first time I saw it run. It comes with a mounting bracket so you can mount it directly to the side of your air handling unit. Unfortunately, the pump didn't mount completely tight and it can move around a little while resting in the bracket. I don't think it will cause any problems though. You have to purchase some 3/8 I.D. tubing to run from the discharge fitting of the pump to a suitable drain. I went to the washing machine drain pipe. The feature I like the most is the HIgh Level Switch. It is a SPDT switch that can be used to shut down the air conditioning all together and/or sound an alarm. I wired it up to do both and it works awesome! I would recommend this pump to anyone. November 8, 2015
Rated 5.0 out of 5.0 by Piece of cake! Hard to say what I liked best about this product. In addition to the positives noted above, the manufacturer tech support was outstanding! They anticipated the homeowner installer, and were available every step of the way for me! I had to alter the product slightly in order to install in my crawl space using the drains as configured. I had to remove the safety switch, because I needed that drain port. I then placed a moisture sensor on the crawl space floor so that I would be alerted in the event of an overflow. They helped me figure out how to do all of this, and get the furnace up and running again. Really great support, they never once talked down to me because I wasn't a professional. Running real smooth for over a month now. No problems! January 21, 2014
Rated 5.0 out of 5.0 by Works as advertised I ordered this pump partly based on reviews and it seemed like a good quality pump. The overflow switch can be wired into most modern furnace/AC control boards. This is a nice feature, especially if you are away from home with the AC on. Pump is quiet and has no issue pumping condensate vertically 6 feet and horizontally 20 feet into a deep sink (We has no nearby floor drains). Overall a great product at a great price.

Rated 5.0 out of 5.0 by This a good pump to buy I was just going to replace my condensate pump with the same brand and model that but I figured I would started to read the reviews of condensate pumps and decided it would be best if I tried a brand with better reviews. Thank goodness for those reviews! I purchased the Little Giant and so far couldn't be happier. I was able to use the plumbing from the old setup. And with the rubber legs I was able to just set it on our crawl space floor next to the furnace. Couldn't have been easier. It is very quiet and has no vibration. I own this pump for almost two months and is going great. No cons July 20, 2015
Rated 5.0 out of 5.0 by It was an easy install. On line research says it's a good product. My Home Depot service desk is great. I am disabled. I went to the desk, told the nice lady what I wanted. It wasn't in stock ( she sent someone to the shelf to make sure) She ordered it one line for me. Free shipping to my Door. It came via UPS. My wife installed it. Simple install. The weather is hot now and that pump is running like a son of gun ! Thank you all so much for helping me. May 30, 2013
Rated 4.0 out of 5.0 by Solid Product I am happy with how smoothly the unit runs. It either moves the water very quickly, or it's control setpoints are closely spaced, or both. It cycles on-off more often than the one it replaced, with an on duration of about 6 seconds. This may be easy to fix, but I don't consider it broken. I expected I could just attach 1/2 inch pex tubing and this was a mistake. I had to wrap the discharge nipple with electrical tape as a temporary bodge. Don't buy new discharge tubing until you have the unit. Just pull the check valve with the nipple on it and take it to the home center to get the right size tubing. I expect it will last at least a year, and that will confirm it was a good buy. The photos show the unit in the box I made to muffle its noise. I used a 2-inch thick piece of foamboard insulation and quite a bit of duct tape. I'll make a plywood box to wrap it with heavy material and I expect it will be nearly silent. February 22, 2014
Rated 5.0 out of 5.0 by Best Condensation Pump This pump was fairly easy to install, well made and runs quietly. The safety switch is a very nice feature from keeping the unit from overflowing. The switch is fairly easy to install, all you have to do is splice into the 24 volt red wire from the thermostat inside heater control compartment. (watch it on youtube) Only complaint I have is, it should of come with a discharge hose, and the instructions don't offer how to wire up the safety switch. Other than that great product, great price.

Rated 5.0 out of 5.0 by A GREAT little pump... This replaced a very loud pump for our AC unit in the bedroom closet (which our HVAC company installed last year). This one is so quiet, we can't even tell when it is running if the closet door is closed. Ordered it from HD online and it arrived in a week. Everything as expected, and a two year warranty. Had it installed 30 minutes after UPS delivered it. I want to order another one just to have on hand when this one eventually gives up. Just a note: This pump has a slightly smaller holding capacity than "standard", so it may run more frequently than you expect if you are replacing a pump with a larger tank. If it were as loud as other standard pumps I've owned that would be a problem, but this is whisper quiet and not a problem at all w/this pump. Again, very pleased. October 9, 2014
