How to Replace a Submersible Sump Pump · Step 5 of 7
In this video
Carefully lower the new sump pump with the attached pipe into the center of the sump pit, making sure it sits level on the bottom and the float switch can move freely. Reconnect the discharge pipe to the main drain line by tightening the screw coupling. Plug the pump's power cord directly into a GFCI-protected outlet. The pump should immediately start running to clear the water in the basin. Watch to ensure it pumps the water out and then automatically shuts off as the water level drops and the float switch lowers.
Goal: Install and test the new sump pump
- Do not use an extension cord. A sump pump must be plugged directly into a GFCI outlet to prevent electrical hazards.
- Ensure the float switch is not obstructed and can move up and down without hitting the sides of the pit.

FAQs
What is the single most critical safety precaution I must take before starting to replace my submersible sump pump?
Always disconnect power to the sump pump circuit by unplugging it or turning off the dedicated breaker at your electrical panel. This prevents accidental electrocution, especially since you'll be working with an electrical appliance in a potentially wet environment. Confirm the power is off using a voltage tester if you're unsure.
The project is listed as 'beginner' and 6 hours. Can I really complete this if I'm new to DIY, and what factors might make it take longer?
Yes, a beginner can successfully replace a sump pump, but taking your time is key. Factors like rusted or seized discharge pipe connections, a very dirty sump pit requiring extensive cleaning, or unexpected plumbing modifications can extend the project beyond 6 hours. Having all your tools and materials ready beforehand will help streamline the process.
Besides the listed tools, are there any other specialized items or tools that would make replacing the sump pump easier or more efficient?
While the listed tools cover the basics, a shop vacuum can be incredibly useful for thoroughly cleaning out a dirty sump pit before installing the new pump. Additionally, a hacksaw or reciprocating saw might be more effective than a PVC cutter if you encounter old, rigid, or difficult-to-reach piping that needs to be cut.
How do I ensure I select the correct replacement submersible sump pump for my existing pit and discharge system?
Before purchasing, measure your old pump's dimensions (height, width), horsepower (HP), and discharge pipe diameter (commonly 1.25" or 1.5"). Also, note the type of float switch (tethered or vertical). Matching these specifications will ensure your new pump fits properly in the sump basin and connects easily to your existing plumbing.
