Ceme Vibration S2 Pump Valve  €6.99

Details:
Ceme S2  self-priming valve
This is a replacement S2 valve - only needed if your model has one already.
S2 priming valves prevent airlocks in the pump and pressurized water from going back into the tank draining the boiler.

This can be hand tightened - no need for PTFE tape or glue.

Includes:

• Pump valve and anti-vacuum one-way brass restriction valve.
• Rubber O ring gasket already assembled.
• Nut for pump tightening.
