Watercolors design: color coding to identify flow rate and stream pattern. Patented construction provides a splash-free stream, well aerated and soft to the touch. Pressure compensating for constant flow from 20 to 80 psi. Anti-clogging dome screen filters sediment and particles. Threads directly into the faucet spout. Vandal resistant by design (install and remove with a special key). Virtually invisible once installed.
