What's included in DIY materials
Sprinkler heads ($3–$15 each)
Spray heads for small/medium areas, rotors or MP rotators for larger lawns. Brand: Rain Bird, Hunter, or Toro.
Valves ($15–$25 each)
One per zone. Rain Bird 100-DV or Hunter PGV are standard. Goes in a valve box buried near the source.
Controller ($85–$200)
Pick zone count slightly higher than you need. Smart Wi-Fi models (Rachio, Hunter Hydrawise) cost a bit more but cut water bills 20–40%.
PVC pipe ($4.50 per 10 ft)
3/4" Schedule 40 for laterals, 1" for mainline. Fittings, cement, and primer extra (~$30 for an average yard).
Frequently asked questions
How much does a DIY sprinkler system cost?
For a typical 5,000 sq ft yard, DIY materials cost $400–$900 (heads, valves, pipe, fittings, controller). A pro install runs $2,250–$4,250 for the same yard. DIY saves $1,500–$3,500 if you do the trenching yourself.
What tools do I need?
A trencher rental ($75–$150 per day), PVC cement, a hacksaw or PVC cutter, a measuring tape, and a $10 water pressure gauge. Most homeowners can install a small system over a weekend.
Do I need a permit?
Most jurisdictions require a backflow preventer (PVB or RPZ) and may require a plumbing permit if you tap a new line into your main supply. Many areas accept a hose-bib tap with no permit. Always check with your local water utility before digging.
How long does installation take?
A 5,000 sq ft yard with 3 zones takes about one weekend (10–16 hours) for one person with a rented trencher. Larger systems or rocky soil can stretch to a full week.
What if I have low water pressure?
Below 30 PSI static, you may need MP rotators or rotors instead of fixed sprays. Below 20 PSI, the system will struggle no matter what — consider a booster pump. Our designer accounts for your actual pressure and picks heads accordingly.
