NEOPERL’s PCA low-flow faucet outlets can help save 70% on water and sewer bills, as well as energy bills (for hot water generation). If concerned about hard water, switch to SLC spray — it includes a silicone tip for a softer, gentler stream and for protection against lime build up. The PCA 0.5 gpm Perlator Laminar stream is pressure-compensating for high performance in all pressure conditions, and its integrated anti-clogging dome screen filters sediment.
