ZeroDrain® is the revolutionary new, patented sink drain from California Faucets. In the open position, the stopper is level with sink, resulting in a superior “zero clearance” design. ZeroDrain is easier to install and service compared to standard pop up drains which saves significant time and money. It meets U.S./Canada plumbing codes and is IAPMO approved. Like most of our products, ZeroDrain is available in 30+ artisan finishes. ZeroDrain - the new standard in sink drains.
