QP4TH TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #3 (01/29/14) — PAGE 17

7.  The discharge hose is usually a 

collapsible  

(thin-walled) hose, however if a thin-walled discharge 

hose is not available, a rigid suction hose can be 

substituted in its place.

8.  Make sure the 

suction strainer

 (See Figure 3) is 

clean and securely attached to the water end of the 

suction hose. The strainer is designed to protect the 

pump by preventing large objects from being pulled in 

to the pump. 

1.  Place pump as near to water as possible, on a firm 

flat, level surface.

2.  To prime pump, remove fill cap (See Figure 3)

 

and fill 

pump casing with water. If the pump casing is not filled 

with water before starting, it will not begin pumping. 

3.  Attach suction and discharge hoses to the pump. Check 

that all hoses are 

securely

 attached to the pump. Make 

certain suction hose (See Figure 3) does not have 

any air leakage. Tighten hose clamps and couplings 

as required.

4.  It is recommended that 2 clamps be used when 

securing the suction hose to the inlet side (suction) 

of the pump. 

5.  Remember suction hoses must be 

rigid

 enough not to 

collapse when the pump is in operation.

6.  Check that the 

discharge

 hose (See Figure 3) is not 

restricted. Place hose so that it lays as straight as it is 

possible on the ground. Remove any twists or sharp 

bends from hose which may block the flow of water.

 NOTICE

Suction and discharge hoses are available from 

Multiquip. Contact your nearest dealer for more 

information.

  

CAUTION

The strainer should be positioned so it will remain 

completely 

under water

. Running the pump with the 

strainer above water for long periods can damage the 

pump.
