C. Obstruction in pump can be indicated by a drop in pressure. If a drop in pressure is
accompanied by a frothy or whitish discharge stream, blockage is in the suction line or
sump area. To clear the pump:
1. Disengage (turn off) the slurry pump clutch and stop engine. Close suction shutoff
valve.
2. Loosen suction pipe clamps. If there is material in tank, stuff a rag into the suction
piping.
3. Remove suction pipe clamp closest to pump.
4. Remove elbow and slowly open suction shutoff valve.
NOTE:
If no water comes out, the obstruction is in sump area.
5. Reach into pump and remove obstruction. If it is jammed, the pump suction cover
may have to be removed.
6. Reassemble, removing rag plugging the suction piping and reopen the suction line
shutoff valve.
D. Obstruction in sump area, which is located at the bottom of the tank on the inside where
the suction pipe is attached. Three methods to remove an obstruction in the sump area
are as follows:
1. Clear the sump by backflushing through the discharge plumbing with the water
supply hose. This is the easiest method.
2. Remove the drain plug and run a long pole through the opening and into the sump
area. Remove the obstruction and replace the drain cap.
3. Use a pipe or pole through the loading hatch opening to dislodge the obstruction.
