This design does get crudded up, but they can be easily cleaned. Pull the unit by unscrewing the six screws on the top flange. Remove the stainless tube, then ensure the rod the float moves on is clean and the float can move easily. Reassemble and you should be good to go for awhile. Lots of fun, by the way....
