Abstract

A system and method for a battery-operated back-up sump pump. The method includes providing a back-up sump pump kit including the back-up sump pump, a first check valve, a second check valve, and a joint. The method also includes cutting a discharge pipe extending from a primary sump pump in a sump pit in order to create a first end open toward the primary sump pump that remains in the sump pit and a second end open toward the discharge pipe leading out of the sump pit. The method further includes installing the first check valve at the first end of the cut discharge pipe, installing the second check valve downstream from the battery-operated back-up sump pump, coupling the first check valve and the second check valve to the joint, and coupling the joint to the second end of the cut discharge pipe.

Claims (18)

1. A method of installing a battery-operated back-up sump pump in a sump pit containing a primary sump pump, the method comprising:

providing a back-up sump pump kit including the back-up sump pump and a case including an integral control charger;

while the primary sump pump remains in the sump pit,

cutting a discharge pipe extending from the primary sump pump in order to create a first end open toward the primary sump pump that remains in the sump pit and a second end open toward the discharge pipe leading out of the sump pit;

installing a first check valve at the first end of the cut discharge pipe;

installing a second check valve downstream from the back-up sump pump;

coupling the first check valve and the second check valve to a joint;

coupling the joint to the second end of the cut discharge pipe; and

connecting the back-up sump pump to a battery stored inside the case of the back-up sump pump kit, wherein connecting the back-up sump pump to the battery includes connecting the back-up sump pump to a panel of the control charger located on an outside of the case, and connecting the battery to terminals of the control charger located on the inside of the case.

2. The method of claim 1 and further comprising installing the back-up sump pump in the sump pit on top of the primary sump pump.

3. The method of claim 1 , wherein the joint is a T-joint.

4. The method of claim 1 , wherein connecting the battery to the control charger includes connecting quick connect leads of the battery to terminals of the control charger.

5. The method of claim 1 , wherein installing the first check valve at the first end of the cut discharge pipe includes coupling the first check valve to the first end via a slip reducer bushing and a slip coupling.

6. The method of claim 1 , wherein installing the second check valve downstream from the back-up sump pump includes coupling the second check valve to a discharge of the back-up sump pump.

7. The method of claim 1 and further comprising installing the back-up sump pump in the sump pit beside the primary sump pump.

8. The method of claim 7 and further comprising installing an elbow connector between at least one of (i) the second check valve and the joint and (ii) the back-up sump pump and the second check valve.

9. The method of claim 1 and further comprising connecting a float switch of the back-up sump pump to a control charger included in a case of the back-up sump pump kit.

10. The method of claim 9 , wherein connecting the float switch to the control charger includes connecting the float switch to a panel of the control charger located on an outside of the case.
