INTRODUCTION

Little Giant Wastewater Kits are carefully packaged, inspected and tested to ensure 

safe operation and delivery. When you receive your unit, examine it carefully to 

determine that there are no missing, broken or damaged parts that may have 

occurred during shipment. If damage has occurred, make notation and notify the 

firm you purchased the unit from. They will assist you in replacement or repair, if 

required. Read this manual carefully and also the enclosed pump manual.
This unit is designed to pump wastewater from laundry trays, washing machines, 

sinks, or dehumidifiers. The unit is not designed to pump raw sewage or flu-

ids other than water. The unit is capable of removing fluids with solids up to 

3/4" spherical. Maximum fluid temperature is 125°F. The unit is designed to fit 

under most sinks so in many cases it is not necessary to recess the unit into 

the floor.

ITEMS TO PURCHASE

NOTE: Some state or local codes require all electrical and/or plumbing con-

nections to be made by a licensed contractor. It is the customer’s responsibility 

to determine codes involved and to comply with these codes. If user can install 

unit, items to purchase are:
  1. Inlet piping, with trap and union (basin cover has 1-1/2" FNPT fitting)
  2. Discharge piping, with swing check valve and union (basin cover has 1-1/2" 

FNPT fitting)

  3. Vent piping (basin cover has 2" FNPT fitting) and 2" union

SAFETY GUIDELINES

 1. CAUTION: Make certain that the unit is disconnected from the power 

source before attempting to service or rework any components.

  2. Read all instructions and safety guidelines thoroughly. Failure to follow the 

guidelines and the instructions could result in serious bodily injury and/or 

property damage.

  3. Check local electrical and building codes before installation. The installa-

tion must be in accordance with their regulations.

    During normal operation the pump is immersed in water. Caution must be 

used to prevent bodily injury when working near the pump.

  a. The plug must be removed from the receptacle prior to touching, servic-

ing or repairing the pump.

  b. To minimize possible fatal electrical shock hazard, extreme care should 

be used when changing fuses. Do not stand in water while changing 

fuses or insert your finger into fuse socket.

ELECTRICAL CONNECTIONS

All wiring must meet local codes, and a licensed electrical contractor is rec-

ommended. The pump is supplied with a 3-prong vented plug. Plugs must 

be plugged into a grounded receptacle and should be on a separate circuit 

with fuse or circuit breaker and GFCI (ground fault circuit interrupter). Be sure 

electrical supply matches pump nameplate data. Do not use extension cord. If 

installed in basement, plug connection should be 4' or more above floor, espe-

cially if basement floods. Be sure electrical connections cannot be reached 

by rising water. Under no circumstances should outlet box or receptacle be 

located where it may become flooded or submerged by water.

INSTALLATION

All plumbing must meet local codes. A licensed plumbing contractor is recom-

mended. All fixtures connected to the WRS-9EN Basin Kit must be vented accord-

ing to state and local codes.
STEP 1: Determine proper location for unit. Unit should be located so that inlet 

is gravity-fed. Unit will not draw water up from a lower level. Position and level 

basin. Keep basin away from any item that could puncture basin. 
The position selected for the basin should be convenient to inlet, discharge and 

vent piping and electrical supply.
STEP 2: Plumb inlet. Using 1-1/2" threaded pipe, plumb inlet to basin cover fitting. 

Use a P-trap and a union next to the basin. Use pipe joint compound and hand 

tighten only on plastic fittings. Do not reduce below 1-1/2" piping.
STEP 3: Plumb discharge. Using 1-1/2" threaded pipe, plumb discharge to 

basin cover fitting. Use of a check valve is recommended to prevent backflow 

of water into sump. Install check valve as close to the top of the basin as possible 

to prevent cycling of pump. Be sure check valve is installed in proper flow direction. 

If check valve is installed backwards, no water will flow out of unit. Be sure the 

discharge piping is sealed with pipe joint compound and the lift height of pump 

is not exceeded. Hand tighten only on plastic fittings.
