There are certain elements to every system that are required and necessary, whether you have a system that has one zone or 20 zones. These constants are:
- Permit from the city, averages $100
- Backflow assembly kit, averages $160
- Automatic controller, average of $100
- Rain/Freeze sensor, average cost is $80
- Backflow test, $75
The average yard zone will have 8 – 10 heads. This will include one valve and valve box, heads, nozzles, pipe, fittings, wire, and wire nuts. The materials cost per zone typically runs around $70 wholesale. Multiply this by the number of zones you anticipate, and you will have an idea of what your materials cost will be. An average sized yard will require around 6 zones for full coverage.
Based on these estimates, after paying the consultation fee and adding in the materials cost, an average sized system can be installed for around $1500. Contact a sales rep for more details.
