Shorewood, Ill.-based MJSI, Inc. announced the issuance of patent 7,926,511 by the US Patent Office for the HydroClean toilet fill valve’s Float Lock assembly.

The Float Lock is an easily movable lever on the float arm that turns the water "Off" or "On" from inside the toilet tank. This invention allows minor repairs to be made inside the tank in a dry environment and eliminates the need to shut the water supply off with the external shut-off valve or at the main water shut-off for the entire building.
