NEOPERL’s PCA SLC spray saves homeowners 70% on their water, sewer, and energy bills. The silicone tip provides not only a softer, gentler stream, but protection against lime buildup. It is available in regular and small sizes, 0.5 gpm, 1.0 gpm, and 0.35 gpm — for maximum LEED points (for U.S. Green Building Council projects).
