Sime Water Rate Adjuster 6281410

The Sime 6281410 is a water rate adjuster rated at 11 litres per minute, used on Sime gas boilers. It forms part of the boiler's water circuit and controls the rate at which water passes through the appliance.

• Domestic hot water flow rate at the tap is lower or higher than expected
• Hot water temperature fluctuates or is difficult to stabilise
• Scale or debris build-up restricting flow through the adjuster
• Flow rate changes noticeably when another outlet is opened
• Low hot water flow persists after other hydraulic components have been checked

• Confirm your boiler model and GC number against the fitment list above
• Check whether the appliance is the natural gas or LPG variant
• Verify the part number 6281410 on the existing component or in the manufacturer's parts list
• Confirm the required flow rate matches 11 litres per minute
