Description
The Watts 7018131 Backflow Preventer First Check Repair Kit is used to restore the first check assembly in backflow prevention equipment. The 6-inch size identifies its application for designated backflow preventer assemblies requiring first-check component replacement. It is placed within the first check section of the valve body during maintenance, and it supplies essential first check assembly components that enable the backflow preventer to maintain controlled one-way water flow within HVAC systems. It works with the existing backflow preventer assembly to support consistent operation, system protection, and continued compliance with intended backflow control requirements.
