HydroSure Rigid Riser with Threaded Adaptor - 300mm - Pack of 10

Begin by piercing a 4mm hole in your main LDPE supply pipe using a hole punch. The threaded inlet attached to the riser can then be easily wound into the 4mm hole by hand using the winged shaped grips located at the bottom of the riser. Alternatively, for a more flexible connection perfect for watering harder to reach areas located away from your main LDPE supply pipe, install the threaded inlet of your riser into 4mm micro pipe up to 4 metres long. Top Tip: Micro pipe's internal diameter means friction inside the pipe increases, so only install in 4m run lengths.

To provide maximum protection against your riser moving around and disrupting the pattern of your micro spray head, install a pipe stake either side of where the riser is installed. The rigid riser should also be clicked into a ground stake to further prevent any unwanted movement. The outlet of the riser features a 4mm thread designed to provide a secure base for a threaded micro spray head.

Rigid risers provide a secure and robust anchorage for a micro spray head to prevent them from moving around when the system is in use which might alter the spray pattern. Ensuring spray patterns remain accurate helps to make certain your plants get the water your system was designed to deliver.

Manufactured using strong HDPE plastic to prevent mis-shaping when installing into a ground stake and to provide a strong stem to elevate the height of micro spray heads. Increasing the height of a micro spray head increases the diameter and radius water is outputted from the spray head – perfect for watering larger areas or beds and borders with more dense foliage.

Manufactured from UV stabilised materials to ensure a long-life and protection against deterioration when in use and exposed to sunlight. Cheaper plastics will begin to fade and crack but you can be certain Hydrosure risers are built to last.
