Reticulation mistakes to avoid

This is by far the most important aspect of installing a reticulation system as if a system has too many sprinklers on it or they are spaced incorrectly then your lawn and garden will suffer. Most reticulation stores will professionally design your system for you provided your purchase the materials from them.A static pressure test needs to be done before the design phase so that you know what your flow is at 250kpa. Each nozzle has a different flow rate so you can accurately work out how many nozzles per stations and the type of nozzle.

Incorrect pipe size


This problem shows up when there is a big backyard and water needs to travel along distance. A pipe size too small will restrict flow and you won't be able to use all the available flow compared to choosing the correct pipe size.  For a bore the pipe size might be a 40-50mm mainline from the bore to the solenoids and reduce to 25mm to the stations. A mains system should have a 25mm mainline and reduce to 20mm to the stations in general.

Installing poly pipe under ground


This is very frustrating and is often done by DIY installers or cheap contractors. Yes, it is cheaper however it’s not watertight and can burst, leak or let sand into the system which can constantly block nozzles resulting in dead patches.

Poly pipe in general is only rated to last up to 3 years. Once it starts leaking or bursting under lawns it’s frustrating and your lawn will suffer however the worst thing is when it starts bursting under expensive pavers or concrete, decking or even under your house. Water can cause significant structural damage over time. Wet wood or soil can attract termites into structures.


Cheap materials that don’t last or produce quality results


There are some cheap products out there like $100 controllers or 80c sprinklers however you really do get what you pay for. The cheaper stuff won’t last anywhere near as long as the quality stuff in general and the results which show up in a beautiful lawn or garden won’t be anywhere near as good.

cheap controllers that don’t last or have full functions


Some budget controllers can be ok but for a little bit more you can have a commercial grade controller with smart features so you can save water via weather station data(Hydrawise) and monitor everything via your phone from anywhere in the world. The Rainbird ESPRZX now has a module you can purchase which gives full smart options and rumour has it that the Hunter X Core might be bringing in the equivalent but with superior Hydrawise software.

If you would like to find out more information on this subject give me a call.
