Sump pump installation may seem like a long afternoon of tools, water, and a messy cleanup. This couldn’t be farther from the truth, sump pump installation is actually a pretty simple process. As long as you have a few hand tools, a steady hand, and a little know how, your replacement sump pump will be in place in a matter of minutes. Remember, if you are replacing your sump pump, it’s probably a good idea to replace your check valve at the same time. A malfunctioning leaky check valve will cause your pump to work harder than it has to. Although the installation is easy remember to read the manual for instructions and safety information before you begin.
Gather the Proper Tools for Replacement
You’ll need a few things before you start:
A length of 1 ” PVC pipe (long enough to go from the sump pump to the check valve).
A PVC adapter from 1 ” PVC to Male threaded (This is to connect your discharge pipe to the sump pump).
A can of PVC cement.
A few 2″ pipe clamps (depending on your installation you should only need 4 5).
A bucket to catch all the water from your old sump pump.
A hack saw to cut the PVC pipe to length.
A screw driver
20 minutes of free time to complete the installation and your favorite beverage for when the job’s done.
Step 1: Removal of Old Pump
Usually, new sump pump installations will inclue a controller, a dual float switch, and the sump pump itself. To remove the old sump pump, unplug the unit from the wall. Remove the discharge pipe from the rubber union or check valve by loosening the pipe clamp. Remember to remove the discharge pipe slowly because there will be water in the pipe above the check valve. Remove the pipe and pump from the sump pit and place it in a bucket to contain any water from the pump.
Step 2: Installing the New Discharge Pipe
Cut a piece of 1 ” PVC pipe to the length so that it will reach from the pump outlet to check valve. Using PVC cement, glue one end of the PVC pipe to the threaded male adapter. Let the fitting dry for approximately 15 minutes before screwing it into the pump outlet. Remember that you must drill a 1/8″ hole in the discharge pipe in a downward slope so that the water will drain back into the sump pit. This will prevent an airlock in the pump. An airlock will prevent the pump from pumping.
Step 3: Installing the New Pump
Slide a pipe clamp down the pipe and connect the float switch (don’t tighten the clamp just yet). Next, lower the pump into the pit by the handle and place it on the sump foot or the bottom of the pit. Position the float switch so that the float is facing away from and below the bottom of the drain tile. This will prevent the water from the drain tile splashing on the float causing the pump to malfunction. Once the float is in place tighten the hose clamp. Now connect the discharge pipe from the pump to the bottom of the check valve on the existing discharge pipe with a pipe clamp. Plug the controller into an A/C outlet and then plug the pump into the controller. For metered installation secure the cables on the discharge pipe in a few places with some wire ties. Make sure that the cables don’t touch or overlap. Your sump pump installation is now complete, pull out that beverage and marvel at your own work.
