1/3 HP - 12-Volt Battery Backup Sump Pump System

A:  I found that about every 6 months you have to put a changer on it for a day. Your batteries my have a bad cell in them. Or your backup is malfunctioning meaning it needs to be replaced. Or you might have to pull the pump out and wash the bottom of it out/remove the screws on the bottom and clean it. I have had to do that to mine. I hope this works.

A:  Cut the existing drain pipe at a convenient place and add a 2" PVC WYE to run a second drain line into your sump pit for the new pump. The WYE will combine the outputs of both pumps into the existing drain line. Make sure both pumps have a one-way flow valve between the pump and WYE to ensure water goes out via the drain line and not back into the sump pit via the other pump. I added a shut-off valve and union on both pumps so that a pump cam be easily removed from service by loosening the union. The shutoff valve keeps water from coming out the open side while the pump is removed. You'll probably need some additional fittings and a short length of 2" PVC pipe. PVC cuts easily with a hacksaw. Be sure to test fit the pieces together before using PVC pipe cement to glue them together! Be sure to set the float switch a little higher than the water level when your main pump kicks on. Once the drain line and pump are installed, unplug your main pump and add water until the backup pump kicks on to test. Don't forget to plug the main pump back in when finished!!

A:  You can connect to the existing discharge pipe but you'll need two check valves to make sure water only moves in the outflowing direction and not back into the sump (essentially one pump pumping back in reverse through the discharge of the other). Each valve fits in line with the pvc via clamps or glued. They are available at HD and are easy to install.

A:  The easiest way would be to use a 1 ½" - 2" reducing coupling, like this one:https://www.homedepot.com/p/Fernco-2-in-x-1-1-2-in-DWV-Flexible-PVC-Coupling-P1056-215/100013986 You could also use a PVC reducing bushing like this one https://www.homedepot.com/p/Charlotte-Pipe-2-in-x-1-1-2-in-PVC-Sch-40-SPG-x-S-Reducer-Bushing-PVC021071400HD/203811557

A:  The cord is six feet long. Be award that some of the cord is under the lid and in my case, the outlet is on the left side of the unit so I only have five feet of usable cord which is plenty for my setup. I've lost power to our house a few times since installing this and it has worked like a charm every time. I wish I had one of these when we got hit by Hurricane Irene - that storm cost me a lot of money in damage!

A:  I'd say approximately 6 feet. The unit is not in my basement. If it was I'd go measure it for you. You can always attach an extension cord. Good luck! John

A:  5ft long from the sump pump to the battery. then from the battery to the outlet is 4ft long. i made a shelve set the battery on so it was out of the water.

A:  aprox. 6 foot

A:  The power cord is approximately 75”.
