Backward Compatible by GM Shortt (Farmington Hills MI US)

I was surprised to find your company on the web since the humidifier on the furnace was here when I bought the house 20 years ago. Even more surprised to see available parts, that fit and work. I thank you for your rapid response and keeping the parts backward compatible. I am in Michigan and have been unemployed for six months. The replacement part saved me some cash. When I am re-employed, I will upgrade the drive and sump pan. Thanks again,

It went in good but was a little tricky getting float adjustment because of tight fit and location, but its just like a toilet bowl tank adjustment, it works great I would purchase again

float valve assembly by Chuck Tillema (Greenfield WI US)

The float valve was easy to install. It took a little time to adjust the float, but over all a quick ptoject. The float works very well.

Float valve assembly by B Wilcox (Denver CO US)

There were no installation instructions, but it was pretty obvious what needed to be done to install the float valve assembly. My only complaint is that the thumbscrew used to adjust the level of the float is on the left side, close to the side wall of the humidifier, making it awkward to use. You almost have to disassemble things to adjust it. But, once installed and adjusted, it works just fine.

float assembly by Robert Iannelli (East Northport Ne US)

I"m a do it yourself homeowner. The float is very easy to install. The only thing that concerns me is that the float is a bit to long and hits the side of the pan. If the float has to be adjusted a little higher it might get stuck. If the float was a 1/4 inch shorter it would be better.
