Rated 5 out of 5 by from Works Great. I mounter the valve today on my TSC !00 Gal. Rubbermaid tank towards the center where the wall is the most vertical. So far it shuts off great doesn't over fill when the wind is blowing strong sloshing the water. So far it works great.

Will this work with the Rubbermaid 100 gal tank? Seems like it tilts when mounted due to the tank wall are not strait.

Asked by: Boontzy
It should not be a problem if it tilts. If overflowing occurs, the unit can be adjusted using the brackets.
