Watts BV-1003 Backwater Valve Bronze Neoprene 3in Slip-On

3-inch Bronze Backwater Valve

The Watts BV-1003 is a slip-on backwater valve designed for floor-drain applications. Its bronze compression plates and neoprene gasket create a seal that stops reverse flow in drainage systems. The stainless-steel light-tension closure spring ensures reliable float operation without excessive resistance. This new valve meets ASME A112.14.1, UPC and IPC standards for plumbing installations.

Slip-On Fit for Existing Pipework

The slip-on connection lets the valve slide over a 3-inch drain pipe without threading or solvent welding. Included bolts secure the bronze compression plates against the neoprene gasket for a tight seal. The round 2 7/8-inch overall diameter matches standard floor-drain openings. No additional adapters or special tools are required beyond basic hand tools for the bolted flange.

Installers Needing Code-Compliant Backflow

Plumbing contractors and facility managers who need a code-listed backwater valve for floor drains will find this unit suitable. The bronze and neoprene construction resists corrosion in typical drainage environments. Buyers who require a larger diameter, a threaded connection or a valve rated for pressurised supply lines should look at other configurations.
