What it is

The Alpha Seal Kit 710 is a seal kit for the 3-port diverter valve used on Alpha Ocean series boilers. It renews the seals within the valve so the appliance can switch correctly between heating and hot water. The kit is supplied by Alpha under part number 6.1000710.

Signs this part needs replacing

  • Water weeping or dripping from the diverter valve body
  • Loss of hot water or heating output as the valve fails to seal internally
  • Seals that appear hardened, swollen or perished on inspection
  • Boiler pressure dropping repeatedly and needing regular topping up
  • Scale or debris collecting around the valve spindle area

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check that the appliance uses a 3-port diverter valve of this type
  • Compare the part number on the existing valve with 6.1000710
