Most water authorities require a check valve to be installed at the tap before a tap timer. Attach this back-flow device to your tap to prevent back-flow. These check valves are suitable for use on drip systems because they also have a Vacuum Breaker Valve to ease the pressure on the drip tube system.

The 20mm check valve is designed to be used with a 15mm garden tap

The 25mm check valve is designed to be used with a 20mm garden tap.

  • Watermark approved
  • Solid Brass Construction
  • Maximum working temperature 1°C to 60°C
  • Maximum pressure rating 1400kPa

The 20mm check valve is designed to be used with a 15mm garden tap and the 25mm check valve with a 20mm garden tap.

Brass Check Valves FAQs

Irrigation systems utilise a variety of pipes, each offering unique advantages. Polyethylene (poly) pipe is a popular choice due to its flexibility, durability and suitability for underground installation. Another standard option is the PVC pipe, valued for its corrosion resistance. Interestingly different parts of Australia, have their different preferences! For applications requiring superior strength and durability, such as central water connections, brass fittings and valves are often preferred because they are highly resistant to corrosion and wear. Copper pipes, while less common in modern systems due to their higher cost, are still valued for their exceptional resilience from ground movement.

The size of piping depends on a number of factors, but the main one is the length of the run. Longer pipe lengths also necessitate larger diameters to minimise friction loss. Higher water pressure allows for smaller pipes, but excessively high pressure may require larger sizes to handle the force. Finally, the desired flow rate at the endpoint also influences the pipe size you’ll need. For more comprehensive assistance, please reach out to our experts.

Preventing leaks in your irrigation system starts with using the right fittings for your pipe type and adequately preparing the pipe ends for a secure connection. Apply thread tape to threaded fittings and appropriate sealant for solvent-welded connections. Tighten fittings securely, but avoid over-tightening. Regularly inspect your system for any signs of leaks to address potential issues promptly.

Yes, burying irrigation pipes underground is a common practice and offers several advantages. It protects the pipes from damage, reduces water evaporation and keeps them out of sight for a cleaner landscape aesthetic.

However, it’s crucial to choose the right type of pipe for underground installation. Polyethylene (poly) pipe is specifically designed for this purpose, thanks to its flexibility and durability. Always check local building codes and regulations for any requirements regarding underground pipe installation.
