Orbit 55015 Half-Inch Zinc Impact Head
Orbit 55015 Half-Inch Zinc Impact Head for replacing an impact head on a compatible base or riser.
Choose this model for replacing an impact head on a compatible base or riser.
- Good for
- Replacing an impact head on a compatible base or riser.
- Look elsewhere if
- You need a complete freestanding sprinkler.
- The tradeoff
- This is a head only, so the mounting connection must already be covered.
At a glance
- Watering method
- Sprinkler
Why it earns a look
- Adjustable arc suits different lawn edges.
- A replaceable head avoids buying another base unnecessarily.
Where it asks for a compromise
- A base or riser is required separately.
Keep the existing base when the head is the missing part
The half-inch male connection is the first thing to match. Once the head fits, its arc and diffuser adjustments let you shape the water pattern around the lawn. A complete spike or wheel-base sprinkler is simpler when you do not already own a suitable mount.
Living with it in the garden
Watch the first cycle to confirm where water reaches.
Clear filters and outlets when the pattern changes.
