Thanks so much for making replacement parts available for this nearly 50 year old furnace humidifier. The replacement is much improved over the original. Exactly what I needed and super fast delivery

Lasted 2 years, that's quite ok. I will buy it again.

Outside nut for water inlet required cutting about 1/4 inch off the line before the existing compression nut could be attached. Unit looks smaller than the original but works just as well.

Lobb 188 Float Valve Assembly by Sandra Walker (Redford MI US)

I am not a mechanic nor do I have any more experience with machines other than a sewing machine. With the ecomomy as it is, I could not afford a furnace repair expert. I was, however, able to figure out with the diagrams how to take out the old assembly and install the new one. It fit and performs perfectly. The part was delivered quickly as promised.
