Preface
Introduction
The ES-38TM for Sewer Laterals represents
the next generation in sewer leak detection.
Measuring the variation of electric current
flowing through the walls of a sewer pipe, the
ES-38TM represents the state-of-the-art in
locating defects that cause infiltration and
exfiltration.
Electro scanning, in contrast to visual
inspection techniques commonly used by
closed-circuit television equipment, locates
all potential cracks and fractures that
represent pathways where water can either
leak into or out of a sewer pipe. If a pipe
leaks electricity, it will leak water.
Most sewer pipe materials such as clay,
plastic, concrete, reinforced concrete, and
brick have high resistance to electrical
current, while defects have low resistance.
As a result, the ES-38TM is your new tool of
choice to help you cost-effectively find pipe
defects and confidently recommend fixes to
your Customer.
Operating Conditions & Safety
The use of the ES-38TM requires access to
sanitary sewer laterals, involves filling
sewers with water, and sometimes operating
along the side of roads, easements, and other
hazardous locations that represent safety
hazards. This User Guide DOES NOT
describe the hazards likely to be encountered,
nor required safety procedures and
requirements that must be carried out when
operating in these hazardous environments or
conditions.
Therefore, operation of the ES-38TM is at the
sole responsibility and risk of the Operator,
who bears full responsibility to ensure that
the required safety procedures for work is
known and carried out.

3. Preparing the Sewer Lateral
A. Plugging the Sewer Lateral
1. Open the clean out.
2. Push the inflatable plug from the ES-38TM Air
Push Rod, into the sewer lateral getting as close
to the lateral’s sewer main connection as
possible.
3. Slightly inflate the plug to 15 psi.
4. Pull the plug back as far as possible (without
forcing) and mark the push rod position at the
cleanout. The plug should be positioned in the
main line, up against the lateral-to-main
connection.
5. Deflate the plug.
6. Pull the plug about one (1) foot (0.3m) into the
lateral.
7. Inflate the plug to the recommended pressure (25
psi) to seal the lateral so that the lateral can be
flooded. Check that the plug is secure by pulling
firmly on the push rod.
B. Filling the Sewer Lateral with Water
1. Attach the Electro
Scan-provided
Diffuser to a garden
hose and place into
the clean out.
2. As water is filling
the sewer lateral, add
salt solution.
3. While filling the
lateral, update the
Smartphone App to
include Direction of
Flow, Diameter,
Depth, Length, Pipe Material, Surface Cover,
Soil Type, Ground Condition, Service type, and
Pipe Shape.

touching RESET.
10

Electro Scan Inc.
ES-38TM User Guide
3. SELECT 2.0 ft. if using the mark, and Zero if
the end of the Probe is touching the bottom pipe.
4. When the pipe cleanout connection is covered
with water, check the total current value that is
displayed on the Total bar graph.
•VCP and Concrete Pipe should be between
15% and 25% of the total height,
•Plastic pipe, 5% of the total height,
•If the total current is less than recommended,
check the Earth Connection.
If possible and without risk of flooding any
upstream connection, it is recommended that the
sewer lateral be filled to the top of the clean out.
This will enable an “electrical” connection
between the cleanout, pipe, and the cleanout
riser.
C. Positioning the Probe for Scanning
1. Push the probe into the pipe until it reaches the
plug.
oAs the probe is pushed through the sewer
lateral, the Distance From Pipe Entrance,
will increase.
oThe total current on the bar graph should
remain fairly constant and above the levels
specified.
oThe defect value on the bar graph (Yellow)
will increase in height when the probe
passes a pipe defect.
oA cable locator (982 HZ) can be used to
establish the surface location and depth of
the probe rod.
D. Recording an Electro
Scan
1. Touch RECORD button.
The defect current trace will
be displayed.
