Why Choose the GROCO BVS Series?

The GROCO BVS-1500 is trusted by boat builders and marine professionals because it simplifies complex plumbing setups while improving safety. By combining two critical components into one, it reduces installation time, minimizes maintenance points, and enhances overall system reliability—making it a smart upgrade for any serious marine application.

Installation Tip

When installing the BVS-1500, ensure the seacock is securely bolted to a backing block and connected to the vessel's bonding system using the provided bonding screw.
