What it is

The Ecopas 3/4 Bypass Valve is an Altecnic component used in heating systems to maintain a minimum flow through the boiler circuit. It forms part of the Altecnic radiator valve range and protects the appliance from low-flow conditions when thermostatic valves close down. The valve carries a 3/4 connection size as stated in its product name.

Signs this part needs replacing

  • The bypass valve no longer holds its setting and flow through the bypass cannot be adjusted.
  • Water weeps or drips from the valve body or its connections.
  • The valve is seized and will not turn when adjustment is attempted.
  • Boiler noise or lockout symptoms appear when thermostatic valves close, indicating the bypass is not passing flow.

Before you order

  • Confirm the connection size required matches the 3/4 stated on this valve.
  • Check the valve is being fitted to an Altecnic radiator valve installation.
  • Verify the existing bypass valve type and location on the system before removal.
  • Isolate and drain down the relevant circuit before work begins.
