The Holman dripping hose comes with 3 flow discs to insert at the tap - these are to help regulate the water entering the hose and avoid excessive pressure, which will split the hose. 

• Clear: 10 L/min
• Green: 6 L/min
• Blue: 3 L/min

The start of the hose is male connector, which can be plugged into a normal hose connector, as shown on the pack.

If you have secondary adaptor in use on the top of the tap adaptor (reducing bush, 20/25mm adaptor), remove this before you start:

The flow discs are inserted to the top of the tap adaptor:

•  Remove the washer from inside the tap adaptor:

•  Check the disc is level and clear of obstruction (important if you've got an older adaptor which hasn't been removed from the tap for a while):

• The tap adaptor can now be reinstalled to the tap.
