FUJIWARA Condensate Pump, Mini Split Automatic Condensation Drain Removal Quiet Pump,for HVAC,Air Conditioner,Dehumidifier,Furnance,Ice Maker,Suitable for A/C 1-5HP 3700W (FUJ—40S)

I purchased the same model 2 years ago and bought this one to replace it. It's currently attached to an 18k btu mini split air handler and works great. The newer model pump is smaller and much quieter than it's predecessor. My old one still works, it was just clogged, so now I have it as a backup.

I use this pump to pump wastewater from my coco hydroponic grow setup. It is the lowest profile sump I have ever seen and works great. Setup is weird cause you have to wire the plug yourself but once that's done it's fire and forget. Note to purchasers - if you expect to have much pressure buildup be sure to attach the snorkel tube, and even use a longer snorkel tube. Failing to do that can allow for leaks. The purpose of this device is to drain slow drips off of a a/c condenser so it's no surprise the stock snorkel may be a bit short for other uses.

Perfect little pump for making the drainage from my portable air conditioner a non-issue. The output was such that I had to drain it DAILY (the manufacturer and reviewers either lied, or have never been to Florida), which was a huge pain, but now I never have to think about it. Installation took about 10 minutes, leak-free with no additional parts besides an adaptor from my AC to the input tube. I can hear it when my home is silent and I'm within 2 yards of it, but even then, it's as brief and quiet as a considerate adult having a sip of water through a straw. Can't yet speak to its longevity, but you can't beat the price and convenience. This little gadget saved my summer!

Had a BlueDiamond MicroBlue that failed. This is the second MicroBlue that failed on another mini-split. I like the MicroBlue pumps but the latest offering does not have a normally closed relay contact inside to stop the mini-split if there is a failure. This Amazon product has a working switch and is faster than the MicroBlue and about the same level of noise, which is quite acceptable. The big difference is the sensing float switch. This product uses a simple float switch but the MB uses a wire sensor. Which is better? The MB device failed and maybe that is the final answer.

It was been working without interruption for the last 4 years. I installed it, monitored it for several months, and then promptly forgot about it. I am not sure why some reviewers have had reliability issues - it has worked without problems or maintenance. This has met and exceeded my expectations, and has allowed me to install my AC unit, with the drain line located above the actually unit itself, and run do so reliably.

Stopped working in 45 days. Possibly a single bad unit and getting a replacement is welcome but a pain to work through.

Product good A+++

Didn't last a year, ugh bought in Aug 2025 and having to replace the unit not sure why it stopped working and can't risk it again.
