CAUTION
! Reduction of plumbing sizes from what is used for the discharges of the primary 115 VAC pump and 12 VDC pump can result in
system underperformance. Discharge piping that is of insufficient size can result in premature pump and/or system operation failure.

NOTICE
!
Do not glue any parts until the entire assembly, including primary pump, has been dry-assembled to verify fits. Fitting plumbing
and routing wiring away from control floats will be much easier on a bench rather than working down inside a sump pit (Figure 2).
Step 1
a. Install flexible coupling onto 12 VDC pump discharge.
b. Position two hose clamps in the grooved recesses of flexible coupling installed on the 12 VDC pump.
c. Tighten the flexible coupling's first hose clamp connection to securely fasten it to the 12 VDC pump discharge.
d. Leave the hose clamp on the opposite end loose for the next plumbing piece.
Step 2
a. A 3/16" diameter air bleed hole has been drilled in the 90º street elbow that is provided with the kit. (NOTICE: Air bleed hole must be located between
the check valve and the 12 VDC pump to prevent the 12 VDC pump from air-locking.) The bleed hole is located so that the water flow through it will be at
a downward angle to prevent splashing from the basin/pit.
b. Slip 90º street elbow into the flexible coupling attached to the 12 VDC pump discharge, and tighten the hose clamp to secure elbow to the 12 VDC pump's
discharge. (When properly installed the threaded elbow connection of the 90º street elbow should be facing straight up toward the top of the sump pit).
Step 3
s
NOTICE
! A check valve is supplied and required for the backup pump's discharge plumbing. This check valve must be installed in the discharge
plumbing between the backup pump and the Wye connection joining the backup pump's discharge to that of the primary pump's discharge.
a. Apply PTFE tape to male threads of provided check valve.
b. Thread PTFE-taped end of check valve into 90° elbow.
Step 4
a. Position two hose clamps in the grooved recesses of the flexible coupling on the check valve installed in the elbow.
b. Tighten the lower hose clamp to secure the flexible coupling to the check valve body.
c. Loosely tighten the upper hose clamp so it does not fall off. This clamp will be used to secure the check valve to the discharge pipe "Wye" assembly.
Step 5
a. Review the discharge plumbing of the 115 VAC primary pump.
s
NOTICE
! A customer-supplied check valve is required in the discharge plumbing of the 115 VAC primary sump pump. This check valve must be
installed in the discharge plumbing between the primary pump and the Wye connection joining the backup pump's discharge to that of the primary pump's
discharge. A 3/16" diameter air bleed hole must be located between the check valve and the 115 VAC pump to prevent the 115 VAC pump from air-locking.
Locate the bleed hole so that the water flow through it will be at a downward angle to prevent splashing from the basin/pit.
b. The 1-1/2" PVC pipe used in making the discharge pipe "Wye" assembly must be cut so as to ensure that both the 115 VAC primary pump and the 12 VDC
backup pump rest flat on the floor of the sump basin when the plumbing is completely assembled and to align connection to the drain piping from the
home. Dry-fit the assembly to confirm prior to gluing (see Figure 2).
c. Once dry-fit confirms that both pumps rest flat on the sump basin floor and the Wye assembly piping aligns with drain piping from the home, secure
all connections by applying approved waterproof adhesive to all necessary joints and confirm that all flexible coupling hose clamps are fully engaged
with plumbing and fully tightened.
