If the basement has water 
or moisture on the floor, do 
not walk on wet area until all 
power is turned off. If the shutoff box 
is in the basement, call an electrician. 
Remove pump and either repair or 
replace. Failure to follow this warning 
could result in fatal electrical shock.
 
 
     A check 
 valve 
must be used on the primary sump 
pump discharge.
 
 
     This 
 pump 
must only be used to pump clear water.  
This pump is not designed to handle 
effluent, salt water, brine, laundry 
discharge or any other application 
which may contain caustic chemicals 
and/or foreign materials. Pump damage 
may occur if used in these applications 
and will void warranty.
Installation
 
                   
 
Installation of this unit may take 
several hours. Before disabling your 
main pump, have ready an appropriate 
means of evacuating the sump.
1.  Turn power to main pump off.
2.  Pump must be installed using 1¼” 
or 1½” rigid PVC pipe.  Do not use 
flexible drain hose.
Pump Installation
The EWP10 can be installed with a 
separate dedicated discharge line 
(Figure 1, Method 1) or tied into the 
existing sump pump line (Figure 2, 
Method 2).
 
 
     Unplug 
 the 
existing AC pump.  Failure to follow this 
warning could result in fatal electrical 
shock.
3.  Verify that the existing AC pump 
is in good working order.  If the 
AC pump is questionable, it is 
recommended that the unit be 
replaced.
4.  Remove any silt or accumulated 
debris from the sump pit and 
surrounding area.
5.  Locate the EWP10 in an ideal 
position in the sump pit. The 
ideal position is approximately 
2” from the bottom of the sump 
pit and located so that it does 
not interfere with any part of the 
existing sump pump.
6.  Method 1 Installation: 
(Figure 1) Cut and dry-fit rigid 
PVC pipe to the discharge of the 
water powered back-up pump.  
Cement all fittings and discharge 
pipe after all pipe has been cut 
and dry-fit together.
 
 
     The 
 discharge 
line installation will vary depending on 
individual circumstances. Using sound 
plumbing practices, route the discharge 
pipe to an exterior wall by the shortest 
path. Keep turns to a minimum because 
they reduce the flow output of the pump. 
The pipe that exits the building structure 
should be sealed and sloped downward 
so the water will not freeze in the pipe. 
Method 2 Installation: 
(Figure 2) Cut the existing main 
pump discharge line and cement 
a “T” or “Y” fitting.  Measure, 
cut and dry-fit the pipe required 
to connect the EWP10 to the 
installed “T” or “Y” fitting. 
Cement all fittings and pipe.
7.  Shut off the municipal water 
supply.  Install a rigid water 
supply line to the sump area.  
Include a shut-off valve in the 
supply line. Flush the supply line 
of all debris before installing the 
automatic valve.
8.  Connect the automatic valve 
assembly with brass vacuum 
breaker to the supply line. Is 
should be located about 6” above 
the basement floor or sump pit 
cover. The supply line needs to be 
supported.  
9.  Attach the hose coupling and 
washer to the brass vacuum 
breaker of the automatic valve 
assembly. 
10. Attach the “L” bracket to the 
automatic control valve using the 
two screws supplied.
11. Install the float rod by threading 
the two parts together.  Using 
the large coupler, secure the rod 
connection by threading the top 
screw to the top part and the 
bottom screw to the bottom part. 
12. Install a small coupler and the 
float to the float rod by inserting 
the float rod through the center 
of the float.  Insert a small coupler 
about ½” above the bottom of 
the float rod and tighten the 
fastener.  Tighten the first small 
coupler installed.
