ReValv is the only retail DIY sprinkler system winterizing solution.
Its simple, easy-to-install patented design allows property owners to winterize above ground irrigation inlet/outlet (I/O) assemblies fitted with backflow prevention (BP) valves.
Once installed, ReValv reduces the complexity, time and costs associated with annual winterizing tasks and virtually eliminates BP valve mechanical failures caused by exposure to harsh weather conditions.
 
Kit contains all parts required to retrofit and winterize one 1” PVC above ground irrigation I/O assembly.
 
All parts and required tools are standard, non-proprietary items to ensure ease of installation and hassle-free repairs if, and when, it becomes necessary.
