The Aquifer™ Field Farm Starter Irrigation Kit is an expandable overhead irrigation package for larger market gardens and small farms.
Twenty high-performance Wobbler sprinklers can be arranged to match your bed layout, water-source location, and watering zones.
Guaranteed against breakage for five years*.
COVERAGE
Designed to cover up to 15,000 sq. ft. (approximately 1/3 acre), depending on layout and available water supply.
WHAT'S INCLUDED IN THE BASE KIT
- 20 sprinkler/Wobbler stands with stainless-steel stepping stakes
- 20 high-performance Wobblers
- 5 hose swivels
- 5 end-of-mainline figure-eight closures
CHOOSE YOUR MAINLINE OPTION
- Add 500' Poly Mainline: includes a 500-foot roll of compatible 3/4" poly mainline
- No Poly — I Will Supply My Own: provide your own compatible 3/4" poly mainline
CHECK YOUR WATER SUPPLY
Plan how many stands to run at one time according to the flow available from your water source. To estimate GPM, time how long it takes to fill a 5-gallon bucket. If your source cannot run all 20 sprinklers at once, divide the system into zones or use shutoffs/valves to operate fewer stands at a time.
Aquifer components are built from heavy-duty, BPA-free poly for long service life.
OPTIONAL ACCESSORIES
- Irrigation Controller
- Additional 3/4" Poly Mainline
- Aquifer Field Stand Riser
- Aquifer Stand Shutoff
- 3/4" Irrigation Filter
- Pipe Cutter for Mainline and Drip
Assembly instructions are available in video format only.

Even Overhead Watering
Wobblers
Senninger Xcel Wobblers are designed to spread water across the soil surface, making them a practical choice for beds and field crops when spacing, pressure, and available flow are matched to the layout.
Wobbler specifications — Senninger Xcel Wobbler High Angle, gray #9 (9/64") nozzle. Approximate flow per head and wetted diameter measured at 1.5 ft:
- 10 psi — 1.815 gpm — 44 ft
- 15 psi — 2.2 gpm — 47.2 ft
- 20 psi — 2.54 gpm — 50.5 ft
- 25 psi — 2.84 gpm — 52.5 ft
Plan for your available water flow. At 20 psi, each Wobbler uses about 2.54 gpm. Four operating together use approximately 10.2 gpm at the sprinkler heads; the water source and mainline must also account for pressure losses. If your supply cannot support all stands at once, use watering zones or individual Aquifer Stand Shutoffs to run fewer heads at a time.
Pressure rating and regulation: Aquifer™ mainline PowerLoc fittings have a manufacturer's rated working pressure of 60 PSI. In our field experience, we have generally not seen fitting problems at pressures approaching 80 PSI. However, this observation does not increase the 60 PSI rating or mean that operating above 60 PSI is recommended. Keep the mainline at or below the rating of its lowest-rated component. If your source pressure exceeds that limit, reduce it at the water source before the mainline with a suitably rated pressure regulator (not sold by Neversink Tools). Most Aquifer Field installations do not need a separate regulator at each sprinkler stand.
Check Your Water Flow
Not sure how many gallons per minute (GPM) your water supply delivers? You can check it in about a minute with a five-gallon bucket and a stopwatch.
- Use the faucet or hose connection that will supply your Aquifer system. Open the water fully.
- Time how many seconds it takes to fill the bucket to its five-gallon mark.
- Calculate your flow: GPM = 300 ÷ seconds to fill five gallons.
Example: If the bucket fills in 30 seconds, your flow is 10 GPM. If it fills in 60 seconds, your flow is 5 GPM.
This measures the flow available at that connection under the test conditions, not the water pressure at your sprinklers while they run. Long hoses, elevation changes, fittings, and multiple running Wobblers can reduce pressure and flow at the heads. If your supply cannot support every sprinkler at once, water in smaller zones or use Aquifer Stand Shutoffs to close individual stands.
For Taller Crops
Adjustable Sprinkler Height
The Aquifer™ Field Stand Riser raises a compatible sprinkler stand by 24 inches, allowing the Wobbler to water above taller crops.

Winterizing
Stay Out of the Way
Designed for working farms, Aquifer™ stands have a compact footprint so you can move through paths and cultivate around the system more easily.
Durable Mainline
Heavy-duty poly mainline and serviceable fittings are built for repeated field use. Check for damaged tubing or loose connections during the season, and drain or winterize the system when freezing conditions require it.

Why Growers Choose Aquifer Overhead Irrigation
Water the Bed Surface
Aquifer™ Wobblers spread water across the bed surface, which is useful for germination and closely spaced crops. Drip irrigation concentrates water near its emitters and can be a good choice for other crops and layouts.
Flexible Watering
Designed around your beds and water supply, an Aquifer™ layout can water multiple beds from strategically placed stands. Actual watering time depends on water flow, operating pressure, sprinkler spacing, soil, and weather.
Keep Beds Accessible
Arrange stands and mainline to leave room for everyday farm work. Aquifer™ components are made for long service life, but sprinkler heads, fittings, and tubing still need periodic inspection, cleaning when necessary, and proper winterization.
Aquifer Field Frequently Asked Questions
The number of Wobblers you can run at one time depends on the gallons per minute (GPM) available from your water source and the pressure at the sprinklers. Aquifer Field Wobbler flow is approximately 1.8 GPM at 10 PSI, 2.2 GPM at 15 PSI, 2.5 GPM at 20 PSI, and 2.8 GPM at 25 PSI. Add the flow required by the Wobblers you want to run at the same time and compare it with your available GPM.
Use a 5-gallon bucket and a stopwatch at the water source. Time how many seconds it takes to fill the bucket completely. To estimate GPM, divide 300 by the number of seconds it took to fill 5 gallons. For example, a 30-second fill time is about 10 GPM.
Divide the system into zones so fewer Wobblers operate at the same time. Aquifer Stand Shutoffs and Mainline Poly Valves can also be used to control which sections or individual sprinklers are running.
Aquifer Field is designed to operate at relatively low pressure. Wobbler output changes with pressure, so use the flow information for the pressure you expect at the sprinkler. Many Aquifer components have a technical working-pressure limit of about 60 PSI.
Usually not. If your source pressure is unusually high—roughly above 80 PSI—reduce the pressure at the source with an appropriate whole-system regulator. Neversink Tools does not currently sell that type of high-pressure source regulator.
The standard Aquifer Field Irrigation Kit is designed to cover up to approximately 3,000 square feet, depending on your layout, water pressure, and available flow.
The Farm Starter Kit is designed to cover up to approximately 15,000 square feet, or about one-third of an acre, depending on layout, water pressure, and available flow.
Yes. Aquifer is designed to be expandable. You can add mainline, fittings, stands, valves, and additional watering zones as needed. The main limitation is whether your water source has enough GPM to operate the added Wobblers at the same time.
Yes. The Aquifer Stand Shutoff installs beneath an individual Wobbler so that sprinkler can be turned off while the rest of the system continues operating.
Yes. The Aquifer Field Stand Riser raises a compatible Field stand by approximately 24 inches.
First shut off the water to that stand or close the ball valve. Remove the gray Wobbler nozzle, inspect it for insects, sediment, or other debris, and clear the blockage. Reinstall the nozzle and turn the water back on to test the Wobbler. Debris in the nozzle is a common cause of a Wobbler suddenly stopping or spraying incorrectly. If your water source regularly carries sediment or particles, adding filtration can help reduce repeat clogs.
A filter is optional and depends on your water source. If the water contains sediment or particles, filtration can help protect the irrigation system and reduce the chance of debris reaching the sprinklers.
