Turf-Tec 6 and 12 inch Infiltration Rings
Operating Instructions
1. You will need: Mariotte Tubes, a stop watch; ruler and water supply before testing can
begin. (An IN6-W Driving plate, bottle jack, and a dead blow hammer should be used in
hard soils.) If you are comparing infiltration rates over a period of time (or not doing a
saturated test), a Moisture Sensor and a Penetrometer reading should be taken as well.
2. Before checking infiltration rate, check the soil moisture at the one, two, three and four
inch levels and record on the monitoring chart. To determine the percentage of
compaction at each test location, a Penetrometer reading should also be taken and
recorded .
3. Place the double ring cutting blades on the area to be tested. (Silicone spray may be
applied to the cutter edges to allow easier and cleaner removal of tool.)
4. Push down on handle while slightly turning instrument back and forth until the rings are
approximately two inches into the soil. (Do not move the instrument side to side, or
twist too much because the soil will be disturbed. Also, excessive twisting can
cause incorrect infiltration rates.)
5. If harder soils are being tested, you can use the IN6-W Infiltration Test Ring Driving
Plate or a board and dead blow hammer to insert the rings into the soil. Be sure to use
care as to not damage or bend the rings with excessive force.
6. If you are using the IN6-W Infiltration Test Ring Driving Plate, a pickup truck bumper
can be placed over the ring with the driving plate and a bottle jack to apply downward
pressure on the plate and rings, ensuring an even insertion into the soil.
7. Once inserted to a depth of two inches deep, fill both the outer and inner ring with clean
water until they slightly overflow. (This is accomplished easiest by filling the inner ring
first and allowing it to spill over and fill the outer ring.)
8. Attach Mariotte tubes to ports provided on the IN8-W and adjust the height of the Mariotte
tubes until the water stabilizes inside the rings.
9. When the water has stabilized at the correct height inside the inner ring and the annular
space, start the timer immediately.
10. After fifteen minutes, anotate the amount of water in ML that has been replaced by the
Mariotte Tubes. Record this number in the monitoring chart.
11. To calculate hourly infiltration rate, multiply the inches that have infiltrated into the soil by
4. Record this information in the monitoring chart as well.
12. To remove the instrument from the soil, use the hand grips to lift the instrument straight
out of the soil. The handles may also require slight turning while lifting the tool out of the
ground. Extract the tool slowly in order not to disturb the soil surface.
13. It is best to get several readings on an area to get the average infiltration rate.
14. If the infiltration rate is slow, a one hour test may be desired. If the Infiltration rate is fast
(as with new sand construction), a five minute test may be sufficient.
15. After using your Turf-Tec Infiltration rings, wash the rings, dry them and spray with
silicone spray. (This will help the infiltration rings to remove a clean plug.)
