All Utopia faucets feature a patented self-aligning plunger action stop with non-rotating tip. The grinding action that causes washer wear in ordinary faucets and leads to drips and leaks is entirely eliminated. Because the underbody parts of Utopia are made of Celcon® , a non-adhesive material, the water minerals that normally cling to the surface of brass faucets will not stick to the Utopia faucet. As a result, corrosion never has a chance to begin. 4" Lav-a-shower faucet with anti-siphon hook up for personal shower.
