The Manifold Extender is an add-on component to the Train Expansion System and attaches directly to the Double Manifold. This extension piece allows you to add a third, fourth, or more pressure washers as needed to your setup, giving you a flexible, modular way to grow your snow output over time. The most important part is the engineered high pressure check valve that is designed for the Backyard Snowstorm system (pressure, flow, etc.)

The High Pressure Manifold Extender must be used as an add-on to the Double Manifold.
