Wayne ESP45 사용자 설명서

1.  Turn power to main pump off.

2.  Pump must be installed using 11/4” 

or 11/2” rigid PVC piping. 

PUMP INSTALLATION
The ESP45 can be installed as a back 
up system with a separate dedicated 
discharge line (Method 1), or tied into 
an existing sump pump line (Method 2). 

1.  Verify that the existing AC pump 

is in good working order. If the AC 
pump is questionable, it is typically 
recommended that the unit be 
replaced with a 1/3 or 1/2 HP pump.

2.  Remove any silt or accumulated 

debris from the sump pit and 
surrounding area.

1.  Locate the ESP45 on a solid, level surface 

in the sump pit. Do not place the pump 
on a loose or sandy surface. Small 
stones or sand may damage the pump 
resulting in potential pump failure.

2.  This pump has a 11/2” NPT 

discharge. If a 11/4” discharge pipe 
is desired, an adapter (not included) 
will be necessary.  Smaller diameter 
piping will reduce pump flow, rate 
and performance. 

3.  A check valve will be required in 

the discharge line of both the Main 
AC pump and the ESP45 pump 
to prevent recirculation of water 
into the sump pit. System will not 
function without two check valves.

4.   Cut a 4’ section of 11/4" or 11/2" 

diameter rigid PVC pipe. Cement 
11/4" pipe to a threaded fitting. 
Cement 11/4" pipe into pipe 
coupling. Attach 11/4" pipe section 
to the ESP45 discharge adapter.

5.  Screw on to pump discharge.

6.  Place the pump with the 4’ section of 

PVC pipe on a solid, level surface in 
the sump pit on an elevated surface. 

7.  Attach a rubber check valve (sold 

separately) to the top of the discharge 
pipe. This will allow the pump or check 
valve to be removed easily for servicing.

8.  Check valve is required for effective 

operation of system.

NOTE: Check valves can be placed directly 
in the pump discharge if desired. However, 
for ease of disassembly, it is recommended 
that check valves be placed above the 
sump as shown in Figure 2.

The remainder of the discharge pipe 
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 fl ow output of the pump. 
The pipe that exits the building structure 
should be sloped downward so that 
water will not freeze in the pipe.

When installing the separate 
discharge pipe, drill through the 
outside wall with appropriate drilling 
equipment. Seal the hole to prevent 
water from entering.

Method 2 
If a separate, dedicated discharge 
is not possible as in Method 1, the 
ESP45 pump can be tied in to the AC-
operated pump’s discharge pipe by 
installing a “Y” connector. Two check 
valves will be required.
1. Locate the ESP45 on a solid, level surface 

in the sump pit. Do not place the pump 
on a loose or sandy surface. Small stones 
or sand may damage the pump resulting 
in potential pump failure.

2. This pump has a 11/2” NPT discharge. 

If a 11/4” discharge pipe is desired, 
an adapter (not included) will be 
necessary. Smaller diameter piping 
will reduce pump flow, rate and 
performance. 

3. A check valve will be required in the 

discharge line of both the Main AC 
pump and the ESP45 pump to prevent 
recirculation of water into the sump 
pit. System will not function without 
two check valves.

4.   Cut a 4’ section of 11/4" or 11/2" 

diameter rigid PVC pipe. Cement 
11/2" pipe to a threaded fitting. 
Cement 11/4" pipe into pipe coupling. 
Attach 11/4" pipe section to the 
ESP45 discharge adapter.

5. Screw on to pump discharge.
