These brass fixed pressure regulating valves are ideal for systems which require reduced & regulated pressure, like drip irrigation systems. For areas with high pressure.

Plastic pressure reducers can’t handle constant high pressure so the benefit with a brass pressure regulator is that you can put one on at the water connection for a drip irrigation system rather than one plastic pressure reducer on each zone.


Please note the pressure regulators that do not come with a check valve, and may not be suitable for use with caravans.

The pressure regulator including a check valve has been designed for use in caravans.

Pressure Reducers & Filters FAQs

Why do my irrigation parts keep blowing apart?

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.

What’s the best type of sprinkler for my garden?

There’s no best type of sprinkler, just better sprinklers for different applications. Gear Drives are better for large areas, over 5m. Pop-Ups are ideal for 1.5-5m & Micro sprays are excellent for anything under that.

Why would I use drip tube instead of sprays?

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.

Can I just punch extra holes into my drip tube?

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!

How many sprinklers can I have on a single irrigation zone?

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.

Should I flush my watering system before running it?

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).

Can I have drip tube & sprinklers on the same irrigation zone?

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.

Do I need a filter on my irrigation system?

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.

Excellent customer service, product was exactly what I ordered I would recommend this company

Arnold M. (Sydney, NSW)
Four star plus.

Luckily the replacement unit was the same length as the old 2 to 1 reducer. So replacement was effected in 15 minutes. The new 500kPa pressure reducer exhibits a higher flow rate characteristic relative to the replaced unit. Supply and postage was prompt.
