Rheem-Ruud SP623336 Vacuum Relief Valve 3/4"LF

The Rheem-Ruud SP623336 Vacuum Relief Valve is a specialty part that is designed to add safety and convenience to HVAC systems, especially those systems which use water heaters and boilers. This relief valve is made of brass material and is used to avert from the formation of vacuum within the system since this can lead to more damages on the equipment. This 3/4” LF (Lead-Free) vacuum relief valve works in such a way that air is allowed into the system in cases where a vacuum is created. This eliminates the vacuum pressure that tends to cause the tank or the pipes to fail, thus preserving the longevity of the HVAC equipment and their efficiency.
