A. Check pump cord cap prongs for tightness and corrosion.
B. Test for power with light bulb.
C. Check fuses and breaker.
D. Allow pump to cool for 5-10 minutes and reconnect, if overload trips again take corrective action.
E. Have line voltage checked and compare with manufacturer's specifications.
F. Disconnect power and check pump for stability.
G. Check number of other devices on branch circuit.
H. Remove pump, disconnect power, connect to rated voltage and actuate control switch.
I. Manually operate control.
J. Disconnect power, remove pump from sump and observe for freedom of impeller and shaft rotation.
K. Add water to sump and observe turn-on.
L. Add cold water to sump and test.
M. Measure sump width and depth and compare with manufacturer's specifications.
N. Measure vertical portion of discharge pipe (over 15 feet is excessive). If discharge pipe length is extremely long, the friction losses may exceed pump capacity. Observe number of pipe fittings and reducing bushings.
O. Evacuate sump.
P. Examine and observe.
Q. Check rotation of impeller.
R. Observe backflow of water from discharge.
S. Observe source and amount of water inrush.
T. Observe and check float or weight freedom.
U. Observe arrow on check valve indicating direction of flow.
V. Check gate of check valve.
W. Remove screen and observe condition.
X. Measure discharge pipe and compare with manufacturer's suggested diameter (should be no smaller than pump discharge).
Y. Measure water temperature.
Z. Manually override control to check pump operations, if override is provided by manufacturer.
AA. Visually inspect power cord for sharp twists or tape over breather tube at cord cap end.
