BBU INSTALLATION INSTRUCTIONS

Risk of electrical shock. At the circuit breaker or fuse box, turn off the electrical power to the sump pump before beginning this installation.

Setup

1.Locate the high water level in your sump pit (that is, the water level at which the existing (primary) sump pump starts - see Figure 1). Mark this point on the discharge pipe with a pencil or marker.

2.Drain the sump pit as far as possible without running the pump dry. Do this by:

A)PIGGYBACK SWITCH: Unplug the pump and switch from the outlet, then unplug the pump from the piggyback switch. Reset the circuit breaker or reinstall the fuse and plug the pump directly into the outlet. The pump will start. Drain the pit and unplug the pump. OR

B)NO PIGGYBACK SWITCH: Reset the circuit breaker or reinstall the fuse and use a non-conducting broom handle or stick to raise the float switch; the pump should start. Drain the pit and then release the switch.

C)ALL INSTALLATIONS: When the pit has drained, turn off (open) the circuit breaker or remove the fuse again to avoid electrical shock while working on the installation.

3.Support the discharge pipe so that it can’t collapse when you take it apart or cut it.

4.If your discharge pipe has a hose coupling, discon- nect the coupling. If not, cut the vertical discharge pipe at any convenient spot above the floor level.

5.Lift the pump and attached pipe out of the sump pit.

Installation

1.Study Figure 2 for suggested layouts.

The Easy-Installlayout works better for deeper sumps and allows a smaller diameter sump (diameter 13-1/2” or larger, depth more than 22”).

The Alternate layout works better for wider, shal- lower sump pits (diameter 18” or larger, depth 18- 22”). The Alternate layout will require that you purchase (2) 1-1/4” x 90° elbows and (2) 1-1/4” x close pipe nipples.

Other layouts may require more pipe fittings.

2.Find the high water level mark you made on the discharge pipe in “Setup, Step 1”. Cut the pipe at this point and set the cut-off piece aside for use later. Clean up and debur the cut ends.

3.Wrap the threads of the Battery Back Up pump (BBU pump) and the 1-1/4” x close nipple with 1-1/2 – 2 turns of teflon tape (see Figure 2). Leave the first thread free of tape and wrap clockwise ( ).

4.Thread the tee, the close nipple, the 1-1/4” x 1-1/4” check valve, and the BBU pump together. To get them tight, hold the pump and insert a large screw- driver down through the tee and tighten the whole assembly with the screwdriver. DO NOT OVERTIGHTEN! When the assembly is tight, the pump and tee should align vertically (no twist – see Figure 2).

5.Glue the cut-off piece of pipe (which you set aside in Step 2) into the top of the tee.

NOTE: If your discharge pipe is 1-1/4” inch, glue one of the reducer bushings supplied with the system into the tee, then glue the pipe into the bushing.

6.Look at your primary pump to determine if you have a check valve in or near the pump discharge. If not, install the auxiliary check valve in the bottom arm of the tee and install the slip coupling on the check valve (see Figure 2). For 1-1/4” discharge pipe, glue the remaining reducer bushing into the slip coupling.

NOTE: If the primary pump assembly already includes a functioning check valve, do not use the auxiliary check valve included in the BBU system. You need one check valve between the primary pump and the tee (to prevent backflow from either pump into the sump pit), but two check valves will restrict the pipe too much.

7.Trial Fit (NO GLUE YET): Place the primary pump assembly back in the sump pit and add (dry) the tee/check valve/BBU pump assembly to it. If neces- sary, also include the 1-1/2 x 1-1/4 reducer bushing and the slip coupling and auxiliary check valve (see “NOTE”, above).

8.Measure the assembly against the hanging upper discharge pipe (where you cut it in Step 1 under “Setup”). Mark the discharge pipe coming up from the tee 1/4” below the point of overlap (that is, you should have an air gap of 1/4” after you cut the pipe). Don’t cut anything yet.
