INSTALLATION INSTRUCTIONS

 Pump power cord is coiled inside the basin for 

shipment. Remove the extra cord from the basin before operation.
Diagrams 1 and 2 show the various connections that must be 

made for proper installation and operation. this is only a guide – 

actual installation may vary depending on the  

particular situation. 
Inlet: a 1½” inlet is provided on the eD-25 sink tank system. 

one method of hook up is to use a 1½” pVC MIp adapter 

or a 1½” pVC MIp marvel connection (or a similar type of 

connection). You may use a 1½” extension tail piece or 1½” pVC 

pipe, it depends on the type of fittings used on the basin inlet. a 

p-trap should be installed once the appropriate connections are 

made on the basin inlet. once these fittings are installed the rest 

of the piping may be plumbed.

Vent: provision has been made for a 2” vent to allow maximum 

volume for any application and proper operation of pump. the 

vent may be reduced to no less than 1¼”. 
Venting is essential for proper pump operation and should not 

be omitted. the eD-25 sink pump system may be vented into an 

existing vent stack or use a BoCCa approved in-line vent. any 

other fixtures in the system must be vented separately from the 

eD-25 sink pump system. Be sure to comply with local codes.
Discharge: Do not restrict discharge line below 1¼”. a check 

valve Must be installed to prevent back flow of water after each 

cycle. If you are using 1½” or 1¼” pVC pipe on the discharge 

line, a Myers CV-170 check valve is recommended. once check 

valve has been installed plumb the discharge line into an 

existing drain line. 
Basin: Myers Model eD-25 sink pump system includes a 

corrosion-resistant polypropylene tank with a gasketed cover. an 

inlet strainer is provided in the basin cover above the inlet. the 

strainer is sealed and held in place with the four thumb  

screws provided. 

MAINTENANCE

power source before doing any maintenance. 
Your sink pump system is manufactured for easy maintenance. 

each unit is individually factory-tested to ensure proper

note: the basin strainer requires routine maintenance.  

the strainer should be removed and cleaned monthly to  

prevent clogging.
