Pump flow rate is reduced:
• Check the pumphead, discharge and injection valve assembly
for any clogging. Clean and reassemble.
• Check for any additional back pressure created since the last
flow rate was conducted.
• Check for any changes in the viscosity of the chemicals being
used. Increase the % flow by adjusting the Flow Rate control
to a higher setting and run a Flow Rate test.
• Be sure that valves have been properly installed in the
pumphead.
Leakage at the connections:
• Be sure that the hose is fully seated and hose connectors are
tight.
• Be sure that valves are tight and O-rings are in place.
Leakage around the pumphead:
• Be sure that the valves are tight and O-rings are in place and
the head screws (hex bolts) are tight.
