Motor Doesn't Turn On
1. Check fuse or breaker and any control or wiring devices in line.
2. Motor starts when hit or tapped lightly - Sticking brushes or other brush problem. Inspect the brushes.
3. Remove the rear cover of motor to check connections. Check for voltage present at motor. If voltage is
present, see next entry.
Pump Spins But Doesn't Pump Water
1. Check direction of rotation. If not clockwise (viewed from brass front-end) reverse motor polarity.
2. Check Prime - Open and re-prime the pump. Check all the fittings, a pinhole leak in the suction pipe will
cause loss of prime. Inspect, pressure-test, clean or replace the foot valve. Ensure no debris are trapped in
the foot valve.
3. Polyethylene Pipe Fittings – Ensure fittings are tight. Gently heat with torch or hot water and retighten hose
clamp with a wrench. Replace stripped clamps. Use stainless steel clamps.
Noisy Pump – A noisy pump indicates cavitation which can cause rapid pump wear.
Unsteady buzzing sound – Indicates leak in suction line allowing air to enter. Try the following:
1. Check for bubbles in inline (transparent) filter or air in outlet water.
2. Check prime. Open and re-prime the pump. Check all the fittings, a pinhole leak in the suction pipe will
cause loss of prime. Inspect, pressure-test, clean or replace the foot valve. Ensure no debris are trapped in
the foot valve.
3. Some inline filters may have a red push-button valve to release pressure for maintenance. If the filter is
incorrectly installed (too high above the water source) the suction may pull the valve open and introduce air.
To prevent this, seal the push-button with silicone sealant or epoxy, or replace the button with a bolt and
nut, sealed with silicon and tightened down.
4. If no source of air leakage is present, water may have high concentrations of dissolved gases which release
as bubbles in the suction pipe. Reduce suction lift if possible. Install an air chamber in the intake line, with
a valve on top. Pour water in to replace air when problem reappears.
Filter clogs frequently
1. Intake too close to the bottom of well, stream, tank etc. Raise it as high as practical to reduce intake of dirt.
2. Improve the development of the water source. Channel clean water into a settling tank and clean the tank
periodically.
3. Install a larger filter or plumb two filters parallel to each other.
Low Flow Rate / Pump Turns Fast and Draws Low Current – Pump is worn out from dirt, rust or other abrasive
particles in water, or from cavitation, from running dry or age. Replace pump head.
Low Flow Rate / Pump Turns Slowly and Draws High Current (may run hot and/or blow fuses) /Pump is Difficult to
Turn
1. Excessive vertical lift, beyond the system's capacity: Exchange the pump head for a model with correct lift
specifications or increase the size of solar array.
2. Misalignment of coupling shaft - Check rubber shaft coupler for damage.
3. Mineral Deposits - Turn shaft with two fingers. If difficult to turn, use vinegar to dissolve the mineral
deposits in the plumbing. Remove pipes from the pump and allow solution to circulate through the pump by
turning it backwards. Replace or rebuild the pump if deposits cannot be removed.
Pump Will Not Turn – The shaft coupler can't be turned by hand. The fuse is blowing or breaker is tripping.
