INSTALLATION INSTRUCTIONS
To get started installing your submersible pump;
1.
Install pump on a hard, level surface such as cement, asphalt, etc. Never place pump directly on earth, clay, or gravel
surfaces.
2.
Install pump in a basin of at least 405 m [16”] diameter and 610 mm [24”] depth.
Piping for Effluent Applications – 19 mm [3/4”] of less solids
ABS, PVC, and galvanized steel are suitable piping materials. Check local building codes before making a selection. Piping
MUST be 32 mm [1 ½”] minimum to carry volume of pipe discharge. If a threaded discharge is required, secure adapter to
volute (bottom casing) with ABS cement. If a threaded discharge is NOT necessary, cement pipe directly to volute.
Piping for Sewage Applications 51 mm [2”] or less solids (DSBW300)
ABS, PVC, and galvanized steel are suitable piping materials. Check local building codes before making a selection. Piping
must be 51 mm [2”] minimum to keep any solids present in suspension in the fluid. If a threaded discharge is required, secure
adapter to volute (bottom casing) with ABS cement. If a threaded discharge is NOT necessary, cement pipe directly to volute.
Check Valves & Air Locking
Check local codes to determine if a check valve is recommended.
Air locking may occur if the sump empties after extended periods of dry weather. When wet weather returns and the sump
begins to refill, air may become trapped below the discharge check valve.
Drill a 3 mm [1/8”] diameter relief hole in the discharge pipe below the check valve. This hole will help prevent ‘air locking’
where a check valve is used. The drilled hole will vent air trapped in the system. Frequent operation of the pump prevents air
lock from occurring.
For best performance of the check valve when handling solids, install in a horizontal position to keep solids from settling in the
valve preventing it from opening and closing.
Basin Cover & Vent
A sealed cover and vent are compulsory in sewage applications but not where only sump water is to be pumped.
However, a cover will prevent foreign solid matter from falling into the sump basin and possibly damaging the
pump. It may also prevent injury.
