- Check local water-restriction rules on watering days/times

- Verify GST treatment and installer insurance
- Ask for an as-built diagram at handover

Water restrictions (allowed days/times, dripline requirements for gardens) are common and locally set. Reticulation is the standard term in WA. Confirm GST treatment.

Frequently asked questions
Should I use sprinklers or drip irrigation?
Sprinklers (pop-up rotors/sprays) suit lawns; drip lines suit garden beds, hedges and pots because they deliver water slowly at the roots with far less evaporation and waste. Most good systems mix both — sprinkler zones for turf and drip zones for planting. Drip is the water-efficient choice where it fits.
What are red flags when hiring an irrigation installer?
No backflow device where it's required, no zone-by-zone quote, no as-built diagram at handover, ignoring local water-restriction rules, and a design that waters everything on one zone regardless of plant needs. An installer who skips the backflow/compliance question is cutting a corner that can be illegal and unsafe.
How much does irrigation repair cost?
Repairs are usually modest: a broken sprinkler head, a leaking valve, a controller reset, or a winter-damaged line. Costs rise if a mainline leak needs digging or the controller/valve manifold needs replacing. A seasonal check-up that catches small leaks early is cheaper than the water wasted by an unnoticed one.
What is an irrigation zone and how many do I need?
A zone is a group of sprinklers or drippers controlled by one valve, watering an area with similar needs. You need separate zones because lawn, garden beds and shady areas want different amounts of water, and water pressure limits how many heads run at once. More zones means better watering but higher cost.
How do I find a good irrigation installer in Bentleigh East?
Use an installer in Bentleigh East who designs to your yard (zones matched to sun, soil and plant type), knows local backflow and water-use rules, and gives an itemized quote by zone. Ask for references and a system as-built diagram at handover so future repairs are easy. Water-efficiency knowledge matters most in dry regions.
Do I need a backflow preventer?
Almost always where the system connects to mains/drinking water — a backflow preventer stops irrigation water (and any fertiliser or contaminants) siphoning back into the supply. Many areas legally require one, and some require it to be tested by a certified tester periodically. Confirm the local rule; it's a safety and compliance item, not an optional extra.
How much does an irrigation system cost in Australia?
Automatic systems commonly run AUD 700-1,300 per zone installed, with a typical suburban yard at AUD 3,000-6,000. Water restrictions push dripline for beds and rain sensors; confirm whether GST is included.
