California homeowners are now learning that their home insurance company requires safety devices such as automatic seismic gas shutoff valves, and smart water shutoff valves. These devices can prevent costly damage and improve safety in the event of an earthquake, burst pipe, or major leak.
At Water Heater Boys, we install these systems to meet code, insurance requirements, and manufacturer standards. Here is what you need to know about each type and our installation pricing.
Seismic Gas Shutoff Valves
A gas shutoff valve is designed to stop the flow of natural gas to your home in an emergency. Seismic models detect ground movement and automatically close, which can help prevent fires or explosions after an earthquake.
We install a code-compliant valve directly on your gas main and ensure it is properly mounted and tested. Once complete, we provide you with a Certificate of Installation that you can submit to your insurance company.
Installation price: $599 flat rate, including labor, materials, and the valve itself.

Moen Flo Automatic Water Shutoff Valves
Water damage is one of the most common and expensive home insurance claims. The Moen Flo is a connected water shutoff device that monitors your water system, detects leaks, and can automatically shut off water to your home.
We install the valve on your main water line and connect it to the Moen app so you can track usage and receive alerts in real time. Moen Flo valves come in different sizes to match your plumbing, so the cost of the valve itself depends on the model you need.
We do not upcharge the cost of the unit, that cost is passed on to you direct from our supplier.
Installation price: $699 including labor and materials (valve not included).
