How to Replace a Submersible Sump Pump · Step 4 of 7
In this video
Before starting, put on protective gloves as the sump pit water can be dirty. Begin by removing the lid from the sump pit. Unplug the old sump pump from the electrical outlet. Next, locate the coupling on the PVC discharge pipe and unscrew it to disconnect the pump from the house's main drain line. Carefully lift the old pump assembly out of the pit. Once it's out, unscrew the vertical discharge pipe from the old pump unit and set the old pump aside for proper disposal.
Goal: Remove the old sump pump from the pit
- Make sure the pump is unplugged before handling it or the water in the pit to avoid electrical shock.

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.
