I would like to use these check valves on a CPVC pipe system for an outside hose bib that will have both a hot and cold water connection via a T fitting. The application is to eliminate backflow of hot water to the cold water side when the HB is off.

Is possible to use this Check Valve at home outside? is affecting the sunlight to this kind of push-in-connector ? I have over the roof some portion of water  installation with a water solar heater. I want to install your push-in with Temperature gauge

Asked by: Hecman
You can use a SB Check Valve outside if it is covered from the elements. The outside conditions may make the plastic piece on the fitting brittle over time and may not last as long as if it were inside. Please call the tech line at 877-700-4242 if you have additional questions.
