What it is

The Sime 6102801 is a pressure-operated diverter valve with a 1-inch connection, designated V35. It is used in Sime gas boilers to switch water flow between the central heating and domestic hot water circuits. This valve replaces Sime code 6102802.

Signs this part needs replacing

  • Domestic hot water runs cold or fluctuates while the heating is on.
  • Heating circuit warms up when only hot water is demanded.
  • The valve fails to switch between heating and hot water modes.
  • Reduced hot water flow rate.
  • Visible leaks or scale build-up around the valve.

Before you order

  • Check your boiler model against the fit list above.
  • Confirm the existing valve is a pressure-operated type with a 1-inch connection.
  • Verify the part number on the existing valve is 6102801 or the replaced code 6102802.
  • Ensure the boiler is isolated and depressurised before fitting.
