The Hunter PGP Ultra and Hunter I-20 are both professional-grade rotors, but they fit different situations.
Hunter PGP Ultra
The PGP Ultra is our normal residential choice for open lawn coverage. It offers adjustable arc and distance, dependable performance, and practical nozzle options.
Hunter I-20
The I-20 is often selected where its built-in check valve provides an advantage, such as a head at the bottom of a hill or a long pipe run where water drains toward the lowest point after shutdown.
Applications that may favor the I-20
- Low points and slopes
- Longer lateral runs
- Commercial areas
- Larger properties
- Pump-fed systems
- High-use turf
- Longer-throw applications
Drainage compared with a seeping valve
A check valve can help reduce low-head drainage, but it does not repair an irrigation valve that is actively seeping. Water that continues long after the zone should have drained requires valve diagnosis.
