Details:
This replacement S2 valve is only needed if your model already has one.
S2 priming valves prevent airlocks in the pump and pressurized water from returning to the tank draining the boiler.
You may need Teflon tape to make the seal watertight.
This is fixed onto the vibration pump and Teflon pipe
Includes:
- Pump valve and brass O ring for extra reinforcement
- The rubber o ring gasket is already assembled.
- Nut for pump tightening
Also available without the reinforcement ring - see Vibration S2 Pump Valve
