Product Description

These Bermad Adjustable Pressure Reducers is ideal for small domestic and commercial applications and are excellent for Low Flow Applications. It is designed for systems that have rather short drip tube lengths, this is handy because a lot of pressure reducers don’t work properly if there isn’t enough water being let out of the drippers or if there aren’t many drippers on a line. Bermad make excellent quality pressure regulators, this product is designed specifically for drip irrigation to create a pressure level that allows the drippers to irrigate at their best, and it is adjustable so you can set it to the level you need.

  • Flow Range: 3.33 – 83 Lpm
  • Max Inlet Pressure: 9 Bar
  • Operating Pressure Range: .7 – 9 Bar
  • Outlet Pressure Range:

    • ​Yellow: 0.5-1.2 Bar
    • White: 0.8-2.5 Bar
    • Red: 2.0-4.0 Bar

Pressure Reducers are absolutely necessary on all drip irrigation systems operating on mains pressure. Because the holes in drip tube are much smaller than in sprays, when the system is in operation there is much more pressure on the fittings and joins in a drip system. Without a pressure reducer the fittings will blow out and the system will need to be repaired frequently.

A common thought is that turning the tap down will reduce the pressure, but that is incorrect, turning the tap down only reducers flow, not the pressure, the high pressure will still be on the fittings.

This Pressure Reducer isn’t rated for constant mains pressure, if you need a pressure reducer for a constant pressure application check out our Brass Pressure Reducers.

Pressure Reducers & Filters FAQs

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.

The main cause of blowout is pressure. Whether it’s poly fittings, PVC fittings or timers, whatever the component, if the pressure is too high for what it’s designed for, kaboom! Simply solve the problem with a pressure reducer & make it a brass one if it’s on your water supply.

Drip tube is excellent in areas of rich dense soil where water spreads nicely throughout. Installed under mulch, the water is delivered with minimal evaporation & wastage, going direct to the root ball.

No, drip tube isn’t simply holes punched into poly pipe. Inside each hole is an intricate dripper which delivers that water nice and evenly. Punching a hole will simply create an uncontrolled leak!

Each sprinkler & nozzle will push out water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler you’re looking at uses & work within your flow limit. For more information, check our Product Guides.

As you install a system, it’s almost inevitable that small fragments of dirt will get into the pipe, for this reason you should always flush out the system before running it the first time. This can be done by leaving an open end at the farthest point of each irrigation zone & operating the zone for 15 or so seconds to flush it out. Then plug it up & you’re good to go! This can also be said for any other times dirt may have gotten into the system (eg: further irrigation repairs or a mains water supply fault).

We definitely don’t recommend it. Typically, drip tube will deliver the water at a far slower rate that sprays. Because of this, if you were to have both on the same zone, the areas with drip would be left far drier than the areas with sprinkler coverage. If you do want to water some areas with drip & some with sprinklers, it can be done, but each will just need to be run on their own separate irrigation zones.

Even on a typical domestic system running on mains water a filter is still a good idea. In the event of a water main fault where rubbish does find it’s way down the line, a filter will protect the system from blockage and or failure. On systems operating off recycled water, like from a tank, a screen filter is mandatory. Debris like silt & dirt from recycled water is the most common cause of blockages of failures in irrigation systems.

Drip irrigation is a water-efficient system that delivers water directly to the roots of plants through a network of drip tubes or emitters. It precisely releases water at the optimal precipitation rate, minimising evaporation and runoff. This targeted approach ensures plants receive the right amount of water, promotes healthier growth and reduces water waste, making it ideal for sustainable gardening.

Drip irrigation offers numerous benefits, including:

  • Water efficiency — Reduces evaporation and runoff by targeting roots directly.
  • Cost savings — It uses less water and lowers bills.
  • Healthier plants — Provides consistent, precise watering.
  • Eco-friendly — Minimises water waste and promotes sustainability.
  • Low maintenance — Fewer moving parts mean fewer repairs.

Ideal for gardens, lawns and agricultural applications, drip irrigation stands as a smart, sustainable watering solution.

To set up a drip irrigation system, plan your layout, considering plant types and spacing. Install a pressure reducer and filter at the water source. Lay drip tubing in a uniform grid throughout garden beds, securing it with pins. Finally, test the system to ensure even water distribution.

Yes, drip irrigation is ideal for both vegetable gardens and flower beds. It delivers precise, consistent water directly to plant roots, promoting healthier growth, reducing water waste, and ensuring optimal hydration for various plants and layouts.

Fully installed by a professional, a domestic irrigation system will come out to about $1000 per zone. And as a DIY project, it can look more like $300 per zone! But of course that’s a very rough estimate, each system is different and there are a lot of factors to consider. Thankfully, we have the only tool around that INSTANTLY give an accurate estimate for your. Try our INSTANT Irrigation Quote Tool here!

To choose the right irrigation system, consider the size and layout of your garden or lawn, the types of plants you’re watering and your water source. Spray systems are ideal for most applications like lawns and gardens, while drip irrigation works well for mulched garden beds and areas exposed to wind and evaporation.
