How Long Does It Take to Install a Sump Pump?

Sump pump replacement can take 2 to 4 hours; however, a first-time sump pump installation can take as long as 8 hours. A plumbing professional can install a sump pump faster than most DIYers. Taking on the project yourself can result in various problems, but we’ll look at the general process of installing a sump pump in your home.

How to Replace a Sump Pump

On average, sump pumps last about 10 years. If the system turns on and off too often, makes grinding or rattling noises, or is rusty or corroded, it should be replaced. Sump pump replacement can be a complex job with many roadblocks. A professional plumber is equipped to deal with any unexpected issues during the process. 

So, you’ve set aside time to consider a DIY sump pump install. Before you attempt the installation yourself, let’s look at an overview of what must be done:

• Gather Your Tools: You’ll need a bucket (or a shop vac for removing water), a drill with a 3/16” bit, a hacksaw, primer/PVC cement, adjustable pliers, an adjustable pipe wrench, a rubber coupling boot, and zip ties. Tools can be purchased and often rented. If you don’t have them, determine if this is cost-effective.
• Remove the Old Sump Pump: Disconnect the power and then the check valve so the water can drain. Remove the old unit, allowing excess water to drain into the bucket. Clean out the pit, remove debris, and check that the bottom of the sump pit has a hard, level bottom. The base should be made of concrete or brick; setting the new pump on dirt or gravel can cause it to jam or wear prematurely.
• Connect the Check Valve and Discharge Pipe: Prime the inside of the fitting and the outer edge of the pipe (if using a glue-in valve). This ensures the glue will bond the two components strongly. Slide the coupling over the piping and attach the fitting. Then apply PVC cement to the inside of the fitting and push and twist the fitting onto the pipe. 
• Measure the Pit: The sump pit’s diameter should be larger than 14 inches. This ensures the float switch fits and can function properly. The pit should be at least 22 inches deep. Also, check the distance from the bottom of the check valve to the base of the pit and the height from the ground to the center of the discharge pipe’s threading. When cutting the PVC pipe, cut it a few inches longer with the hacksaw, allowing for final cuts later if needed.
• Connect the Adapter and PVC Pipe: The male-threaded adapter is now glued to the pipe. Using the primer and PVC cement, attach the adapter to one end and thread the adapter end of the pipe onto the pump. Tighten it with a wrench. Overtightening it can cause the fittings to crack.
• Test the Sump Pump: Before fitting the pump in the pit, plug the system in and move the float, allowing the unit to run for a few seconds. If you hear the pump running, switch the float. Don’t let it continue to run dry.
• Drill the Weep Hole: Holding the pump at an angle, measure about two finger-widths above the adapter and drill a hole. The drill should be held at a 45-degree angle. The weep hole allows for water drainage and prevents damage caused by water flowing back into the pit.
• Cut the Pipe: Cut the PVC pipe while it’s elevated. Use a crate or other object to lift it off the ground. The pipe should be a few inches longer than the length you previously measured. Remove any frayed plastic with a utility knife.
• Place the Pump in the Pit: Take final measurements to ensure the discharge pipe fits under the check valve. Use towels or rags to soak up any water. Lift the pipe, cut it to its final length, drop the pump back in, and connect the piping. To test the system, fill the pit with water and see if the pump turns on and that the check valve closes when it turns off.

What to Know for a First-Time Sump Pump Installation

A sump pump is designed to keep water and moisture out of your basement. You’ll first need to decide on the type of system to install. A submersible sump pump is the most common type, and it is usually installed as your home is being constructed. It sits in a sump pit within a waterproof housing. A pedestal sump pump sits above the floor and has a motor and hose that lead to the pit; it’s often installed after a home is built and moisture issues have been identified.

When installing any sump pump, make sure it is upright to avoid flooding. Also, make sure all pipes and hoses are tight and follow the manufacturer’s guidelines for periodically cleaning the unit. Also, check for holes or damage that can prevent water from flowing away.

Should I Consider DIY or Professional Sump Pump Installation?

As you can see, sump pumps can be challenging and time-consuming to install (if you have no experience, you can waste several hours or days). Unexpected issues can lead to damage and costly repairs. An experienced technician can install a new unit or complete a sump pump replacement in a shorter time and enable your investment to last longer. They can also make sure all connections are secure to avoid flooding and other unexpected issues.
