Desert Spring Furnace Air Humidifier System DS2800 with Drain, White

Water float valve fitting should be designed to fit the hole when passing the hole of the housing. In other word, the threads on the brass fitting should be cut off and make into flat surface on both sides.

This unit seems to be working really well. The great thing about it is the overflow pan and drainage to prevent potential flooding. Our last humidifier overflowed and caused a lot of damage to our basement floor.

With a mix of reviews, I wasn't sure what to expect. In my case, I was satisfied with the unit itself. It has done a great job to elevate the humidity in my house and we have been able to level it off to maintain a reasonable 30-35% RH. I have a bigger home (3,000SF) with a lot of exposed wood surfaces that had been starting to creak and squeak with a long run of frigid temperatures. The humidity was down around 20% when I decided I needed to do something. The installation instructions are daunting to say the least. If you have a little know-how, it won't be a challenge, but I needed a few extra pieces that I recommend (1/8" shrink tube for the thermostat-to-motor connections is ideal, and aluminized ducting tape is a must for the round-duct connections). It would also be nice if the instructions provided a complete sketch of the finished product so you could work towards something. There are a lot of words that can cause confusion (especially since this is reversible to suit different installation requirements). The humidistat is not accurate (but that's to be expected). I have a couple smart-home devices that I use to check the humidity in the home, and then adjust the humidistat settings to suit. So far, no issues with overflowing or wasted water, and I don't see how it could, as long as you maintain the float valve and ensure the unit is level when installed.

I bought this, fully knowing that some work would likely be required, based on other reviews. Installation went fairly well but when I installed the foam drum, I noticed that I had been sent 2 fully enclosed ends and that the air source pipe was a good 1.5 to 2 inches from the drum. I drilled big holes in the one end and 3D printed a cover to ensure most of the air would get into the center of the drum. A week or so after getting it working, I found the bottom water tray just decided to come loose and there was a good puddle of water under the unit. I highly recommend putting a band of tape around the box closest to the return duct to help prevent this from happening. After quite a bit of the expected extra effort was put in to getting this going, it's actually doing a pretty good job of keeping the humidity level at a much more comfortable level in the house (around 40% where as before it was in the 20 to 30% range).

Great product. Easy to install and runs very efficiently.
