RK12-420 Repair Kit for 420 Series 1/2”-3/4” Pressure Vacuum Breaker (PVB)Restore Sealing: Resolve leaks by replacing the rubber O-rings and gaskets.Rebuild Check Valve: The spring and poppet in the repair kit ensure water flows only towards the showerhead and never backflows.Restore Air Inlet: When line pressure drops, the float sinks to open the air inlet, breaking the vacuum and preventing the siphon effect from drawing dirty water back in.Cost Savings: Replacing the entire relief valve internal parts yourself with a repair kit is much more cost-effective than removing and replacing the entire brass valve assembly.
