What it is
A hydraulic 3-way diverter valve, sold by Glow-worm as the 'Hydroblock Flow', part number 0020064049. It routes the boiler's output between central heating and hot water when a tap is opened, which is what lets a combi boiler supply both from one unit.
Signs this part needs replacing
- Boiler produces heating but no hot water, or vice versa
- Water dribbles from a tap when the heating is running
- Clicking or humming noise from the valve when switching
- Boiler gets stuck cycling between heating and hot water modes
Before you order
- Confirm the part number on your existing unit reads 0020064049
- Isolate electrical power and water before removing the old unit
- Fitting should be carried out by a Gas Safe registered engineer
