I installed six Hunter PGP-Ultra rotors in my backyard two years ago. Before that I had the original Hunter PGP rotors that came with the house. They were old. One had a stripped gear. Another would not rotate at all. I needed replacements and the PGP-Ultra was the obvious upgrade. Here is why I picked it and how it has held up.
Hunter is one of the two big names in irrigation, right alongside Rain Bird. The PGP-Ultra is their flagship residential rotor. It covers 22 to 52 feet depending on the nozzle. That range makes it flexible for different yard sizes. One rotor can handle a small front lawn or a big backyard.
What the Hunter PGP-Ultra Brings to the Table
The PGP-Ultra comes with a set of color-coded nozzles. You pop in the right nozzle for your spacing. Red nozzles are for short throws. Blue for medium. Grey for long. The arc is adjustable from 40 degrees to a full 360. And the whole adjustment can be done with water running using the included Hunter key.
| Feature | Spec |
|---|---|
| Type | Gear-drive rotor with pop-up |
| Spray Distance | 22 to 52 feet (nozzle dependent) |
| Arc Adjustment | 40 to 360 degrees |
| Pop-up Height | 4 inches |
| Inlet Size | 3/4 inch NPT |
| Nozzle Options | 12 color-coded nozzles (0.5 to 14 GPM) |
| Check Valve | Built-in (holds up to 10 feet of elevation) |
| Warranty | 5-year manufacturer warranty |
My Real-World Experience With the PGP-Ultra
The first thing I noticed during installation was the 3/4-inch inlet. Most residential rotors use 1/2-inch fittings. The PGP-Ultra uses a bigger inlet. That means more water flow and better performance at lower pressures. It also means you might need adapters if your system uses 1/2-inch swing joints.
The nozzle system is what sold me. Hunter packs a full set of 12 nozzles in the box. You do not have to guess which nozzle you need and order it separately. The color coding makes it obvious. Red nozzles throw the shortest distance. Grey nozzles throw the longest. I used blue nozzles for my backyard because my heads are spaced about 35 feet apart. Perfect match.
The built-in check valve is a feature I did not know I needed. My backyard has a slight slope. With the old rotors, the lowest head would drain all the water from the zone after shut-off and create a wet spot. The PGP-Ultra check valve holds back up to 10 feet of water column. No more wet spots at the bottom of the slope.
What I Like About the PGP-Ultra
- Full nozzle set included — 12 color-coded nozzles, no separate purchases needed
- Built-in check valve — prevents drainage and puddling on sloped yards
- 3/4-inch inlet — better flow and performance than 1/2-inch rotors
- Smooth gear drive — quiet rotation, no chattering or sticking
- Easy arc adjustment — use the Hunter key while water is running
- Wide coverage range — 22 to 52 feet means one rotor model fits many yard layouts
- 5-year warranty — Hunter stands behind their products
What Could Be Better
- Higher price than basic rotors — you pay for the extra features and quality
- 3/4-inch inlet may need adapters — not a direct swap for 1/2-inch systems
- Plastic housing — tough plastic but still plastic, not metal
- Nozzle changes require shutting off water first — you cannot swap nozzles mid-operation
- Hunter key is easy to lose — it is a small plastic tool, buy a spare
Hunter PGP-Ultra vs Rain Bird 5004: Which Rotor Is Better?
This is the big debate in residential irrigation. Both are excellent rotors. Both cover similar distances. Both have reliable gear drives. Here are the real differences that matter.
The PGP-Ultra has a built-in check valve. The basic Rain Bird 5004 does not. You need the 5004-SAM version for that feature. The PGP-Ultra uses a 3/4-inch inlet. The Rain Bird 5004 uses a 1/2-inch inlet. Bigger inlet means the PGP-Ultra handles higher flow rates better.
The Rain Bird 5004 is easier to adjust. The arc and radius adjustments are more accessible and easier to turn. The PGP-Ultra adjustments work fine but require the Hunter key and a little more finesse.
My take: If your yard has slopes, get the PGP-Ultra for the built-in check valve. If adjustability matters more, get the Rain Bird 5004. You cannot go wrong with either.
Is the Hunter PGP-Ultra Worth the Money?
Yes, if you want a rotor that covers a wide range and includes features that usually cost extra. The built-in check valve alone saves you from buying the upgraded version. The included nozzle set saves you from buying separate nozzles. At around $12 to $15 per rotor, the PGP-Ultra is a solid investment for any residential in-ground system.
Who should skip it? If your system uses all 1/2-inch fittings and you do not want to mess with adapters. If your yard is perfectly flat and you do not need a check valve. In those cases the Rain Bird 32SA or 3500 will do the job for less money.
Frequently Asked Questions
What nozzles come with the Hunter PGP-Ultra?
Twelve color-coded nozzles from 0.5 GPM to 14 GPM. Red for short throws (22 to 30 feet). Blue for medium throws (30 to 40 feet). Grey for long throws (40 to 52 feet). Each color has several flow rate options.
How do I adjust the spray pattern on the PGP-Ultra?
Use the included Hunter adjustment key. Insert it into the top of the rotor. Turn clockwise to increase the arc. Counterclockwise to decrease it. Adjustments can be made with the water running. The radius is adjusted by turning the radius adjustment screw.
Does the PGP-Ultra have a check valve?
Yes. The PGP-Ultra has a built-in check valve that holds back up to 10 feet of elevation. This prevents water from draining out of the lowest heads in a zone. The original PGP model does not have this feature.
What size inlet does the PGP-Ultra have?
3/4 inch NPT. This is larger than the 1/2-inch inlet on many residential rotors. If your system uses 1/2-inch fittings you will need a 3/4 to 1/2 adapter.
Can I use the PGP-Ultra with a garden hose?
No. The PGP-Ultra is an in-ground rotor. It threads into underground piping. For hose-end use, look at the Hunter PGP-ADJ on a spike base.
How many PGP-Ultra rotors per zone?
Plan for head-to-head coverage. With a typical 3 GPM nozzle and 10 GPM zone capacity, you can run 3 to 4 rotors per zone. Always calculate based on your actual flow rate, pressure, and nozzle selection.
