Frequently Asked Questions

A: Check the label on your existing wind pressure switch or consult your appliance's user manual. The pressure rating is typically printed on the original switch. Match the rating exactly for safe, reliable performance.

Q: Is this wind pressure switch compatible with my brand of gas water heater?

A: This switch is universally designed to fit gas water heaters and wall boilers that share the same shape and specification, including Haier, Macro, Squirrel, Vanward, and Vatti models. We recommend comparing the shape, connector style, and pressure rating of your current switch with this one before ordering.
