This common problem in Lyndon homes often stems from pressure changes in your plumbing system.

How Thermostatic Mixing Valves Work
A thermostatic mixing valve monitors water temperature directly rather than just pressure.

This technology provides superior protection against scalding and ensures consistent comfort. The valve also includes a safety feature that shuts off water flow if either the hot or cold supply fails preventing sudden temperature extremes.
