Use this 18mm Drip Line Pipe with 18mm Barbed Connectors

Drip Line Installation Tips

Create a drip line system individually tailored to your garden layout by using 18mm irrigation connectors and components to either snake the pipe through plants in a flower bed or install it as a gridded network. For a discreet irrigation system that does not distract attention from your beautiful floral blooms, cover the drip line in a layer of garden mulch or bark up to 10cm below the surface.



Water-Saving Irrigation

Using drip line for garden irrigation ensures precise irrigation that expertly delivers the exact amount of water your plants need to thrive yet, conserves precious water resources by consuming up to 70% less water than manual watering methods. Drip line delivers a constant steady stream of water directly to the root zone of the plant maximising absorption and reducing surface runoff.

Working Pressure

As Drip Line functions best at working pressures between 0.5 to 1.75 bar (and up to 4 bar for longer run lengths), for optimal performance, install a Pressure Reducer at the start of the system.

Drip Line Fittings

HydroSure Drip Line has a narrow 1.1mm nominal wall thickness and wide internal bore resulting in maximum water flow and minimal pipe friction for longer run lengths and enhanced performance. As Drip line is quoted by its internal diameter (18mm I.D and 19.2mm O.D) use 18mm Barbed/Nut Lock Connectors that fit inside the pipe bore. For a more secure fit and protection against pipe blow off if using barbed connectors, install a Ratchet Clamp at each connection outlet.

Drip Line Frequently Asked Questions

  • How to calculate drip line run lengths?

    Use the equation in our Water Flow Rate Guide to calculate the flow rate from your tap. Then, use the below calculation to check if your water flow rate is sufficient to run your required length of drip line.

    (Required length ÷ Dripper Spacing) x L/h Output from Each Emitter = Total Water Output Overall

    Working Example: (50m ÷ 0.33) x 2 L/h = 303 L/h

    If your required length is to water a 50-metre hedge row and your dripper spacing is 33cm emitting 2 litres per hour from each emitter, you would need a minimum flow rate from your tap of around 300 - 350 litres per hour.

  • How to set up an irrigation system over sloped landscapes?

    Pressure Compensating Drip Line is ideal for vegetable patches, garden beds, hedges, and nature strips across varying terrains. Pressure-compensated emitters ensure consistent water delivery along the entire length regardless of the location or elevation of each dripper within the system.

  • Which Drip Line is best for a longer length of hedge planting?

    HydroSure 17mm Drip Line is ideal when running longer lengths of pipe. Ideal for larger garden beds, hedges, and nature strips, the larger diameter reduces pipe friction reducing pressure loss allowing more efficient watering across longer distances.

  • Can drip line be buried?

    We recommend choosing HydroSure13/14mm Anti-Siphon Drip Line.

    The in-built drippers feature anti-siphon mechanisms which compensate for and balance differential pressure. The vacuum within the pipe prevents the aspiration of soil and sand particles through the dripper outlet. 

  • My Drip Line isn’t working

    Common Drip Line Problems

    Dry spots and some drippers not working: Over time emitters can become clogged with insects or dirt. Flush the system by removing the end caps and switching on the water flow to flush out any debris.

    Structural Damage: Digging in the garden can pierce the pipe wall and affect emitter performance. Walk along the length of your drip line whilst the system is switched on to see if there is any visible damage. For drip line that has been buried, check for areas where water is pooling which might indicate a split pipe. Damaged irrigation pipe is easily replaced by cutting out the damaged pipe using Pipe Cutters and connecting the drip line back together using a Barbed/Nut Lock Joiner.

    Pressure Loss: Make sure any open end of the drip line is plugged using an End Cap. This maintains water pressure at the correct level for emitters to function.

  • Can Drip Line be run from a Water Butt?

    Connect a small drip line system from a Water Butt. We recommend using 4mm drip line or a short length of up to 15 metres of 14mm Non-Pressure Compensated Drip Line or Micro Drip LineTop Tip: Irrigation systems fed directly from a water butt rely completely on the pressure generated from gravity. To increase the pressure, raise the height of your water butt by installing it on a Water Butt Stand. For more information, visit our Water Butt Irrigation System Guide.

  • Can Drip Line be left out during the winter?

    HydroSure Drip Line is manufactured from high-quality weather-resistant materials and can remain in place without uplifting at the end of the watering season. To further prolong the life of the pipe structure and emitter outlets, flush the system throughout the watering season and at the time of final watering before the winter months. To flush a drip line, remove the End Caps and switch the system on for 2-3 minutes to allow any internal debris to wash out. Switch the system off and allow the pipe to drain before replacing the end caps to ensure there is no sitting water. Once the system has finished draining, replace the end caps to prevent insects from crawling in and blocking emitter outlets.

    Top Tip: A Flushing Valve or Adjustable Valve can be installed instead of an end cap for dual-functioning flushing and draining capabilities without cutting the pipe and purchasing new end caps each time. 

  • Drip Irrigation vs. Soaker Hose

    Both Soaker Hose and Dripline are effective watering methods as they deliver water directly to the plant's roots. Drip line, however, delivers a uniform application of water with much longer run lengths up to 200 metres that are both consistent and easily measurable by litre per hour output. Dripline is also available with built-in Pressure Compensation ideal for sloped terrain and Anti-Siphon varieties for reliable protection against debris-clogging the emitters when installed sub-surface.

    A soaker hose is a more flexible irrigation method as water seeps through the porous layers along the length rather than at individually spaced outlets where the drip line is concerned. Whilst the soaker hose is easier to set up as it is compatible with connectors that fit a regular garden hose pipe, it is limited to run lengths of up to 30 metres when using a 13mm Soaker Hose and up to 80 metres when using a 16mm Soaker Hose.

    The accurate and reliable delivery of water from drip line requires initial expense and maintenance in terms of additional Filters and system flushing to minimise emitter blockages. Soaker hose, however, tends not to block so requires minimal planning when building a soaker hose system.

  • The best Drip Line for sandy soil

    In sandy soil, water moves quickly in a vertical wetting pattern. Closely spaced HydroSure Drip Line (15cm) with a higher flow rate ensures water remains available for the roots.
