It's working now, but needed quite a bit of adjusting to fit into the reservoir.

Autoflo 188 Float Valve Assembly by John H. (Barre VT US)

Very good customer service, friendly and helpful. The new part fit into the replacement of the old obsolete part and worked without any adjustment. If I remember right, it was free shipping too.

Problems fitting by Eric Schultz (PLAINVIEW NY US)

I have an old AutoFlo 200P humidifier. The original float is not longer available. (If you have one let me know). I researched the internet and the only replacement piece recommended is the Autoflo 188 Float Valve Assembly. AutoFlo suggests it as a replacement as do a few other sites.However, a number of reviews suggested that it was too large and gets stuck thereby permitting the water to keep entering the unit. I ordered one with the idea that if it did not fit I would return it. However, I seem to have limited options if I want to keep the unit. As it turns out, the assembly is slightly too long for the tank and would not prevent the water from leaking. I did fashion as solution. I lowered the arm, which was simple. There is one screw to lower the arm instead of the two used in the old unit. Those were also difficult to adjust while installed. I also used a pair of plyers to push up the lip of the upper unit where the float was hitting it. After some adjustment it has worked, (so far). If you need to replace the old float then you can use this one with a bit of adjustment to it and the humidifier. Otherwise you have to either fill the tank manually or get a new humidifier.

Fast Shipping, Work Great by ( )

I accidentally broke the floater of my AutoFlo 97. I couldn't find the replacement part for the original one. I came across this and ordered one. They shipped it by 2nd day Priority mail. They saved me a lot of aggravation.

Works great by Charles Harris (charleston wv US)

Fit nicely in place of obsolete unit. Working fine with no leakage. Cotter pin needs to be shorter. It could catch on drum as it rolls past.

A very welcome engineering change to the float valve that works with minimum adjustment. I think it should last much longer and do a better job than the old configuration. Easy order and prompt shipping.

Autoflo 188 Float Valve Assembly (replacement) by Ray C ( Yo )

The float valve mounted easily and is working well. But the adjustment screw is on the back side of the piece when placed on the left side of the unit, as mine is, making it difficult to operate.

It works! by JP Schmelzer (Oak Park IL US)

Autoflo was easy to find on the internet. The part was easy to find on the site and the part came in about a week after ordering. The part was easy to install. All is good.
