The cartridge’s nickel plating prevents both corrosion and impurity buildup. The main valve seat is below the supply-line inlet, which allows the lines to be flushed with 100% confidence. Delany’s proprietary Rubberflex handle assembly is simple and easy to use while assuring years of leak-free operation. The piston valve is available in all LEED HET gpf outputs and can be ordered with the company’s patented dual-flush SmartHandle.
