Low flow faucet outlets can help save on your water, sewer and energy bills (for hot water generation). The SLC spray includes a silicone tip for a softer, gentler stream and for protection against lime build up. Rub the silicone tip to clean the outlet. Replacing an aerator with the PCA 0.5 gpm, Perlator Laminar stream, allows for a crystal clear stream. It is pressure compensating for high performance in pressure conditions, and its integrated anti-clogging dome screen filters sediment.
