CALIFORNIA APPROVED - Special 1.8 GPM flow restrictor to meet California energy regulations. UNLIKE OTHER SHOWER HEADS THAT are made from cheap, thin plastic that leaks after a few showers, the Aqua Elegante Shower Head has a THICK LAYER of ROBUST ABS THERMOPLASTIC RESIN that is BPA FREE. The high pressure showerhead RESISTS CORROSION, WITHSTANDS PHYSICAL IMPACT, and DOESN'T RUST - while still being LIGHTWEIGHT and EASY-TO-HANDLE. What this means to you is a LONG LASTING shower head without having to deal with internal leaks. DON'T PUT UP WITH SHOWER HEADS THAT clog up or spray in weird directions. We engineered our showerhead with SELF-CLEANING NOZZLES made from MINERAL-RESISTANT SILICONE. The nozzles are shaped to jet water flow, which PREVENTS CALCIUM BUILD-UP inside and on the nozzles. You NO LONGER NEED TO WORRY about hard water clogging up your spray nozzles. NO MORE DEALING WITH shower heads that barely trickle out water or needle your skin with thin streams
