3. SPECIAL FAULT LOCATING PROBLEMS

1. Finding faults under concrete. Dissolve approximately 1/4 cup of salt in
one gallon of water and soak two large sponges in the salt water. Wrap the
sponges over the end of each probe and attach with a rubber band. Now
proceed as described in 2.7. Re-soak the sponges often and dampen the
area where sponges are placed.
2. Obstructions over the drop. It is not necessary to be directly over the
drop path to indicate the fault location. The drop path could be under a
street, driveway, or sidewalk. In this case, if the soil parallel to the drop path
can be probed (up to 15 feet away), you can locate the fault. Accuracy will
not be exact compared to following the path.
3. Multiple faults. Multiple faults will cause the receiver to reverse at each
fault; the most solid fault will produce the strongest signal, kick, or reversal.
The best policy is to repair the first fault you locate and then reconnect the
Pulser and locate the next one, until you have cleared all the trouble.
4. High resistance faults. A very high resistance may produce a weak kick.
To help make this fault easier to locate, simply turn the sensitivity
all the way clockwise. Pouring water on ground stakes will increase
sensitivity.
5. Long distances to the fault. Extreme distances between the transmitter
and the fault can cause you to lose signal for a distance between the
transmitter and the fault. This is no real problem. Note the distance from
the transmitter to the point you lose signal.You will pick the pulse up the
same distance from the fault. For example, we will use a distance of
100 feet between the probing. The pulse will be received 100 feet on either
side of the fault.
