Hydrosure Pressure Compensated No Drain Micro Irrigation Dripper – 8L/h - Pack of 100
55 In Stock
Ideal for watering sloped areas or long run lengths. The built-in check valve advocates water-saving capabilities preventing output after switch off. See Full Description
A water-conscious option for irrigation technology. The in-built check valve reduces water wastage by opening when the system is turned on and exceeds 0.5 bar and closes when the system is turned off and pressures reduce to below 0.3 bar. The check valve also means your system is less susceptible to mineral build-up inside the supply tubing as calcium deposits that clog drippers are less likely to form.
Simple to Install and Maintain
Attach directly into LDPE pipe by piercing a hole in the pipe wall and inserting the barbed inlet of the dripper. Alternatively, install using 4mm micro-pipe (in lengths up to 4m) directly from the tap using a 4mm barbed tap connector or feed from LDPE pipe by inserting a 4mm joiner into the pipe wall. Use a ground stake to secure in place so water droplets are accurately delivered.
Pressure Compensation
Pressure Compensating drippers offer the perfect solution for watering sloped areas or large run lengths as drippers emit exactly the same amount of water regardless of elevation or location within the system. Top Tip: Pressure compensating drippers self-compensate between 1 – 3 bar pressure and require a pressure reducer at the start of the system to function optimally.
Time and Water Saving
Using a micro-drip system not only saves time but also uses up to 90% less water than manual watering and sprinkler systems. Drippers can be positioned to deliver water with pinpoint accuracy directly to the roots of the plant. Automate your irrigation system by installing a water timer so you can irrigate your garden even when you are on holiday!
Micro Drippers Frequently Asked Questions
Some of my Micro Drippers are not working!
Common Problems
Drippers not emitting: Check the flow rate from the tap using our Water Pressure and Flow Rate Guide. A flow rate of 540 LPH and a Dripper output of 8 LPH means up to 67 emitters can be run in a single zone. (Flow Rate Divided by Emitter Output).
Dry spots: Emitters can become clogged with insects or dirt. Regularly flushing the pipe network, dismantling the drippers and cleaning them under running water prevents blockages.
Structural Damage: Digging in the garden can puncture the supply pipe affecting emitter performance. Locate leaks or water pooling and fix the pipe by cutting out the damaged section using Pipe Cutters and re-connect using a Joiner.
Pressure Loss: Make sure any open end of the pipe is plugged using an End Cap. This maintains water pressure at the correct level for emitters to function.
My Micro Drippers keep clogging and blocking!
Use an Irrigation filter at the start of your system to prevent naturally occurring sediment from clogging dripper outlets.
Drippers that Prevent Blockages
Drippers with a Check Valve prevent calcification of the internal pipe by keeping water in the system after it is switched off.
Self-Flushing Drippers have a turbulent flow patterned labyrinth preventing sediment from settling and flushing out unwanted debris.
How much does Micro Drip irrigation cost?
Components used to build a Micro Drip system are often inexpensive with a small system starting from around £24.
HydroSure Drippers, Pipe and Connectors are a built-to-last and cost-effective solution manufactured from durable UV-stabilised plastic offering resistance to deterioration from direct sunlight and harsh weather conditions.
Can I buy more Micro Drippers to extend my current system?
Yes, simply connect the additional pipe using a Barbed or Nut Lock Joiner. Alternatively, 4mm Joiners and Micro Pipe can be used to tap into the wall of the LDPE Pipeto take drippers up to 10 metres away from the main supply.
How do I hold Irrigation Pipe and Drippers in position?
Properly uncoiling the irrigation pipe helps with installation. Make pipe easier to work with by weighing it down on either end with a brick and allow any bends to settle. The pipe can then be secured into place every metre and at either side of where a dripper is positioned using Pipe Stakes.
Can a Dripper be inserted into garden hose pipe?
No, hose pipe is manufactured from flexible PVC that when punctured to insert a Micro Dripper frays the surface and does not create a watertight seal.
Instead, insert Micro Drippers into the wall of Irrigation Pipe. LDPE Pipe has a rigid wall that a Micro Dripper can lock into. Alternatively, use alongside Micro Pipefor installations up to 10 metres away from the main supply.
Will a Micro Drip System over winter or does it need to be
removed?
HydroSure Micro Drippers are manufactured from high-quality polypropylene and silicone to ensure longer-lasting durability. For this reason, Drippers can remain in position over the winter months.
Top Tip: Avoid the impact of thawing and freezing by removing the End Caps or using a Valve in place of an end piece. Run water through the system for around 2 minutes to flush out any debris.
Micro Irrigation Drippers vs Drip Line
Both Drippers and Drip Line regulate water flow based on the plant’s water consumption requirements. Whilst Drip Line is easier to set up, Micro Drippers enable flexible placement flower beds, planters, hanging baskets and pots rather than being confined to the pre-set spacings of Drip Line.
Drip Irrigation vs Micro Sprinklers and Spray
Sprinklers and sprays irrigate multiple plants from a single emitter whilst Micro Drippers use up to 80% less water and deliver it directly to the plant's roots where it is needed most.
