  • Conserves water


The HydroClean 550 and 660 are adjustable, water-saving toilet fill valves designed to replace conventional fill valves, which waste water by overfilling after flushing. (A 1.6 gpfGallons per flush. Measurement of water use in toilets. Since 1992, toilets sold in the United States have been restricted to 1.6 gpf or less. The standard for high-efficiency toilets (HETs) is 1.28 gpf. toilet may use more water in a flush cycle, because of waste during refill.) Once installed, the valve is easily adjusted to control the amount of water that flows into the bowl during refill, preventing excess water from overflowing into the bowl and down the drain. The manufacturer claims savings of 16-78 ounces of water per flush with 1.6-gallon toilets. The HydroClean also prevents slime and sediment buildup in the tank, which can lead to silent leaks. Patented Turbojet Technology forces water to the right side of the tank where buildup typically occurs. The J-Tube — with the 660 only — extends across the bottom of the tank and will alert you, with an audible sound, that there is a leak in the toilet. The J-Tube is also used to clean the tank during the water refill process.
