What it is

The Altecnic 22mm CxC Single Check Valve is a single check valve in DZR brass, fitted with 22mm compression connections at both ends. It forms part of the Altecnic check valve range and allows flow in one direction only, preventing backflow within the pipework. It is listed for use on boiler installations.

Signs this part needs replacing

  • Water passing back through the valve when flow should be stopped
  • Reduced flow rate through the valve, suggesting an obstruction or a stuck internal component
  • Rattling, chatter or humming from the valve during normal flow
  • Weeping or dripping at either compression connection

Before you order

  • Confirm the pipework is 22mm and that both connections are compression, not threaded
  • Check the flow direction required, as the valve must be installed to suit it
  • Verify the existing valve's connection type and size against the removed part
