Draw Your Property to Scale
Use the Property Sketch Sheet (page 7). Each small square
on the graph paper should represent one square foot of actual
property or use a scale such as 1" = 10', 1" = 20', etc. Using a
tape measure, measure your property and draw it to scale on
the graph paper (see sample drawing on page 8).
1. Outline your house, garage, and other structures.
2. Show walkways, drives, slabs, patios and other surfaces.
3. Identify trees or major obstacles.
4. Measure and record the perimeter of your property.
5. Identify slopes.
6. Show ground cover, grass, flower beds and landscaping.
7. Identify the location of the water meter (or pump) and
main line.
Additional grid paper is available at www.ToroDesign.com.
Determine Your Soil Type
You can easily determine your soil type—sand, loam or clay—
using a clean empty jar with a lid, clean tap water, a
tablespoon of detergent and a sample of the soil from
your yard.
1. Fill the jar about
1
⁄3 full with the soil to be tested.
2. Add water and detergent and cap the jar.
3. Shake the jar vigorously and set aside for several hours.
4. Evaluate the results and record on the questionnaire.
Sand Soil: Water is clear and soil has settled to the bottom
of the jar.
Loam Soil: Water is still murky with bits of suspended matter.
Clay Soil: Water is murky and there is a ring of sediment
around the jar.
Determining the Service Line Size
Contact your local water company or wrap a piece of string
around the pipe once and then measure the string. Use the
chart below to determine the supply line size/diameter.
Record the line size on the questionnaire.
Determine Your Water Pressure and Flow
Water pressure and flow can be determined using a Flow &
Pressure Gauge or by performing a bucket test and using a
standard pressure gauge.
Using a Toro Flow and Pressure Gauge
The Toro Flow and Pressure Gauge is designed to measure
water pressure up to 160 PSI and water flow up to 13 GPM.
The gauge is not intended for use on lines larger than one inch.
Measure static pressure:
1. Ensure all water inside the home is turned off.
2. Attach the flow gauge to the outdoor faucet closest to
where the main line enters the house.
3. Ensure that the gauge is completely closed.
4. Open the outside faucet slowly.
5. When the outdoor faucet is fully open, read the static
pressure and record it on the questionnaire.
Measure dynamic pressure and gallons-per-minute (GPM):
1. Open the flow gauge slowly. (The static reading will drop
and the GPM will rise as the gauge is opened.)
2. Continue to open the gauge until pressure drops to 50 PSI.
3. Record the GPM at 50 PSI on the questionnaire.
4. Continue to close the gauge to 45 and 40 PSI and record
the GPM readings.
If the pressure does not drop to 40 PSI or is above 50 PSI after
opening the flow gauge all the way, then take the flow and
pressure reading at the full open position. If rapid fluctuation
occurs on the flow gauge, record the average reading.
Using a Bucket and Standard Pressure Gauge
1. Locate the outdoor faucet closest to the water supply line
(Call this Faucet 1).
2. Select a different outdoor faucet on the house and attach a
pressure gauge (This will be Faucet 2).
3. With Faucet 1 closed, open Faucet 2 all the way and record
the static water pressure on the questionnaire.
4. With Faucet 1 open all the way, check the pressure reading
on the gauge at Faucet 2. (If less than 40 PSI, turn down the
water flow from Faucet 1 until the reading reaches 40 PSI.)
5. Place a 5 gallon bucket under Faucet 1 and time how long
it takes to fill it. Use the chart below to convert to GPM to
determine the water capacity at 40 PSI.
6. Repeat this procedure at 45 PSI and 50 PSI and record the
results on the questionnaire.
7. If pressure is greater than 50 PSI record that reading.
