Installing a submersible well pump, continued.
Process A: Steps 1 through 5, At The Pump, Cable, Continued, Splice Check
STEP
You must check pump cables and splices for
5
electrical leaks with an ohmmeter. Refer to drawing
to the right.
STEP 1: Fill a bucket with water. Submerge pump
cables and splices completely. Leave bare wire ends
of cables out of the water.
STEP 2: With the ohmmeter selector knob on Rx
100K and the ohmmeter leads clipped together,
adjust the ohmmeter needle to zero.
STEP 3: Submerge one ohmmeter lead in the water.
Clip the other lead to first one bare wire end, then
the other. If the ohmmeter reads infinity (∞), the
cable splice is watertight. If the needle defects to
zero on either cable, there is a leak in the splice,
or damage to the cable insulation. Slowly pull the
cable that registered zero from the water. The point
at which the needle falls back to infinity (∞) is
the point on the cable where it is damaged, or has
a leaky splice. It must be repaired with a cable
splice kit.
STEP 4: To repair, mark the damaged spot, then slip
a piece of heatshrink tubing down the damaged
wire and shrink it on with a torch (see Step 3,
Page 5). No connector should be necessary.
You may write the installation date, service date and other
important notes regarding your well pump for your records here.
