Pressure Reducers & Filters

Pressure reducers lower incoming water pressure to levels suitable for drip irrigation, preventing damage to emitters and tubing. Filters remove dirt and debris from the water, helping to prevent clogs and ensure reliable, long-term system performance.

Yes, using both is recommended. The filter protects your emitters from clogging by debris, while the pressure reducer ensures water pressure is consistent and safe for drip components, maximising system efficiency and lifespan.

Install the filter directly after the water source or tap, followed by the pressure reducer before the main drip tubing. This setup ensures only clean, properly pressurised water enters your drip lines.

While different drip tube brands & models have different specifications, most will operate reliably between 100 kPa and 200 kPa (about 15 to 30 psi). Operating within this pressure range ensures that the emitters deliver water evenly and efficiently along the length of the drip tube without causing leaks or blowouts. Pressures that are too high can result in emitter or tubing damage, while pressures that are too low may lead to uneven water distribution. Using a pressure reducer is recommended to maintain optimal pressure for your system.

While you can lower the flow by turning down your tap, this does not reliably control water pressure for drip irrigation systems. Tap pressure can fluctuate due to changes in the main supply or other water usage in your home, which may still lead to pressure spikes that can damage drip tubing and emitters or cause uneven watering. A pressure reducer is specifically designed to maintain a consistent, safe pressure for your drip system, ensuring efficient and reliable operation.
