25 mm PE irrigation pipes

25 mm PE pipes for irrigation

PE pipes with a 25 mm diameter are a popular choice for small and medium garden irrigation systems. They are suitable for underground water distribution and can be used as main supply pipes or as lines supplying individual irrigation zones, depending on the required water flow.

A 25 mm PE pipe can supply pop-up rotors, pop-up sprays, drip irrigation and other areas of your garden irrigation system. Whether this diameter is suitable for a particular irrigation zone depends on the required flow rate, pipe length, available pressure and the connected irrigation components.

25 mm PE pipe for home gardens

For many private garden irrigation systems, 25 mm PE pipe provides a practical pipe diameter. It can be particularly suitable for supplying individual sprinkler groups and other irrigation areas where pipe runs are moderate and the required water flow is within the capacity of the planned system.

When planning your system, calculate the combined water requirement of all pop-up rotors or sprays operating simultaneously. Pipe length and elevation differences also affect pressure loss. If higher flow rates or very long pipe runs are required, a larger diameter such as 32 mm may be more suitable.

Connect and install 25 mm PE pipes

Compatible 25 mm PE compression fittings make installation straightforward. Straight connectors extend pipe runs, elbows allow changes in direction and tees create branches. Threaded fittings can also be used to connect solenoid valves, manifolds and other irrigation components.

Cut the 25 mm PE pipe cleanly and as squarely as possible using a suitable pipe cutter. Insert the pipe into the appropriate compression fitting and assemble it according to the fitting instructions. This allows you to install many irrigation pipe systems yourself without complicated specialist tools. Check all connections for leaks under operating pressure.

Supply pop-up sprinklers with 25 mm PE pipe

25 mm PE pipe can be used to supply pop-up rotors and sprays when the flow rate and pipe length are suitable for the planned irrigation system. Individual sprinklers can branch from the PE pipe using tapping saddles and suitable flexible sprinkler connections.

Several irrigation zones can be controlled separately using solenoid valves and automated with an irrigation controller. With 25 mm PE pipe, suitable compression fittings, sprinkler connections and careful planning, you can build a reliable automatic garden irrigation system yourself.
