What it is

The Sime 6319643 is a discharge cock used on Sime Murelle Elite and Murelle PRO boilers. It provides a controlled drain point on the appliance's water circuit, allowing the system or boiler to be emptied during service or repair work. It is a small brass-bodied valve component supplied as a single part.

Signs this part needs replacing

  • Water weeping or dripping from the discharge cock body or outlet
  • The valve spindle will not turn, or turns without shutting off the flow
  • Scale or corrosion around the valve, restricting operation
  • The drain point cannot be fully closed after system draining
  • Visible damage to the outlet or body following service work

Before you order

  • Confirm the boiler model and product code against the fitment list above
  • Check the part number 6319643 matches the number on the existing component
  • Inspect the surrounding pipework and seals for damage before refitting
  • Confirm whether any washers or sealing components are required separately, as they are not stated here
