Little Giant VCMA-20ULS 115 Volt, 80 GPH, 1/30 HP Automatic Condensate Removal Pump for HVAC/Refrigeration Systems/Dehumidifiers with Overflow Detection Switch and 6-Foot Cord, White/Black, 554425

This is the second one I have bought. There’s nothing wrong with the first one, it just had been working continuously for five years and ended up eventually getting clogged with the bacteria slime that was coming out of the dehumidifier, that needed to be replaced. I loved it so much, and it worked so well, that I just bought the exact same one. I have to run my dehumidifier constantly in my basement, but in order to have it be effective I need it in the middle of the room and not tucked away in the corner in the laundry room. Which means I have to run a hose up into the ceiling tiles, across the ceiling, and then drop down into the laundry room sink. This compressor works so beautifully that it easily pushes the water up 7 feet, across 15 feet, and then down into the laundry room sink. So if you have a distance that you need your water to travel, this is the product for you! It’s also extremely easy to use when you’re hooking it up to a dehumidifier. The hose from the dehumidifier goes into one hole and the hose that the water travels through sticks onto the nozzle. And then you plug it in and you’re done.

Hooked this up to my dehumidifier in the basement and it works great. Pumps water from dehumidifier to drain eliminating the need to empty dehumidifier.

First, the crap and gunk that this unit battled - I am amazed that it was still running. Here are some notes from my experience:- + DON'T ASSUME THE PUMP TANK IS CLEANED WITH ANNUAL OR PERIODIC SERVICES. Many companies (I have experience with a fairly wide range) will do just enough to clear the lines and keep the unit functioning. Not once have any of the companies *ever* cleaned this tank. + DON'T ASSUME THE PUMP IS REPLACED WHEN THE FURNACE IS REPLACED. We had a huge, new Lennox system installed and the not inexpensive, certified installers just left the old pump in place. If the photo wasn't so terrible, I'd attach it. Cannot believe this Little Giant battled through. + DRAIN LINE. There was so much gunk in the unit that the line out was also full of sediments. I replaced it based on guidance from amazon contributors. It was not at all difficult. I think you will do much more for your own unit than someone normally has time to do on a usual service. If you want it replaced, it is probably something you'd have to specially request. + DRAIN LINE CONFIGURATION. There are notes on how to do this given your specific location (rise precedes horizontal run, length, etc.). Mine was twisted, tied so tightly to the pipes that it was constricted in multiple places, and the run configuration was inverted. The Little Giant manual contains relevant info. as well. + REPLACEMENT. For less than $50 it is much, much more economical to replace the pump. There are also many good notes in the reviews -- together with You Tube vids. + INTAKE PIPES. I just knew before I removed the unit, I'd find that the ends of the pipes were not only flat cut, but also almost flush up against the bottom of the tank. A read of the very straightforward installation instructions highlights this as an issue. It's just not something the normal retail customer would even know to check until a water or functional issue develops. Cut at a 45 degree angle. + P TRAP. So important and so often overlooked. Equipment manufacturers may not really focus on these, and service technicians are busy once there's an obvious fail. My installation was riddled with errors. No wonder it has been leaking for years. Every time I asked about it, every co. agent just said, yeah, they do that. Well they do if they are not installed correctly. It is easy to check the levels and venting requirements by reading 1.5 pages of the manual. Risks of improper installation: water damage to the system and area, and worse, distribution of substandard air throughout the house. + MAINTENANCE. The tank needs to be flushed and cleaned regularly. That's IMPORTANT. From what I gleaned, that's a minimum of every 2 years........ but realistically at *least* annually (with that service contract) and possibly more frequently in humid or damp areas. I have friends who are GREAT service technicians. I admire their skills. The thing is that unless you understand the equipment in your own house, it's hard to appreciate those talents -- and also know when someone is lacking. It also helps to do some normal maintenance to preclude issues. Edit: The check valve (and float switch) supplied with the unit are working well; no issue and there is a 10 ft vertical run preceding the inverted U down to the drain entry point. Nevertheless I will cut in a second check valve given the length of the vertical rise.

1. Works 2. Not loud when discharging water and only stays on long enough to empty out water, almost 10 seconds easy to install. 3. NO tools required, just put back the PVC drain pipe and put the discharge hose back on, the pump comes with the connector to slide the rubber tubing on with ridges on it to keep it on tight, but I did use Tie Wraps for extra protection to keep the hose from slipping off, probably not needed. 4. Empties pretty much most all of the water when float turns on the pump to discharge the water, stays on several seconds to get all water out. 5. I stuck finger down inside water container and it was full and when pump discharged the water, it was empty, and my discharge copper pipe is long and goes UP from foundation floor, UP inside the A/C closet, UP through the attic and comes down outside at bottom of foundation. 6. It shoots the water out of the 50' copper pipe with lots of pressure to empty the copper pipe completely. 7. LONGEVITY??????????? Just put it in today, we will see, the one I replaced was working for the last 25+ years, and is STILL working but the plastic was so old it cracked and was leaking from the water tank.

This is a great pump. The check valve works as it should and with the units large storage capacity it doesn't need to cut in very often. It does make some noise but compared with the unit it replaced it is very quiet. Our old unit ran almost continuously as there was no check valve so the water was always siphoning back, I can't believe we didn't replace it sooner. Love this unit.

Perfect was a replace for my old one that broke Was able to swap it out in under 10 minutes Prime it tested it and ready to go!

A good simple replacement which does the job as expected.

So our Little Giant VCMA-15ULS has finally croaked after making terrible gurgling and groaning sounds of death for a while. Not knowing the first thing about operation/installation of these pumps, I called a couple of local HVAC repair shops, to get a feel for how much the pump repair/replacement will cost. None of them wanted to give me a straight answer as to an average cost without an actual appointment, which prompted me to check the web for who sells these pumps (in Canada), and for how much. I am very much a DIY woman, whenever possible, so I found an exact model of pump right here on Amazon but, since the drain hose is probably about 25 feet long, to the nearest drainpipe, I decided to upgrade to the stronger motor VCMA-20ULS model. The sweetest thing was the Prime delivery - I ordered yesterday evening, and the pump arrived in less that 24 hours. After that, all it took was a quick scan of the product's "manual" (very straightforward, and in actual English), and Youtube video by this nice and knowledgeable lady known as "Know How Now", and I got to work. It took me about 30 minutes, with modifications such as length of drain tube, hardwiring to the existing wiring, leveling, and about 1/2 gallon of distilled water to prime the unit, and the test of the functionality of the furnace-humidifier-pump system passed with flying colors. I am very pleased with the pump, the price, and the shipping time, and would highly recommend this sweet Little Giant to everyone!

Every single house in North America that needs a condensate pump is probably running a little giant. That's just how it is. I've never seen one fail in my life. My house needs 2. I have one on my furnace, and one on my water heater (it's a heat pump water heater). They both work as they should. I bought this unit because it has the overflow switch I wired to my water heater so it'll stop heating water if the pump fails. And I keep a spare on hand in case that happens. I don't suspect it ever will.
