PRELIMINARY TEST RUN
WARNING: All electrical wiring or service
should be done by qualified electrician. Be sure to
test cable for continuity with an ohmmeter before
starting the pump.
1. All wells should be flushed clear before allowing
water into the house. (Fig. 1)
2. Open an outside faucet and allow water to
run until water is clear of sand or any other
impurities. If an outside faucet is not available,
place softener in bypass position, remove aerator
from a high-flow faucet and allow water to run
until it is clear of impurities. Once clear, turn off
water flow, replace aerator and put softener back
into service position. (Fig. 2)
CAUTION: Be sure you do not stop pump
before water runs clear. This may take several
hours. If pump stops with sand in it, it may lock.
3. If pump lowers water in the well far enough
to lose prime, either lower pump in the well (if
possible) or throttle (slow down) the discharge of
the well with the gate valve to match the capacity
of the well. (Fig. 3)
NOTE: If the well is low capacity, use a low water
level control.
