How to Replace a Sump Pump

Sump Pump busted? Well save yourself the hassle of finding a plumber, and spending hundreds of dollars on replacing it by doing it yourself!

That’s right, swapping out a broken sump pump for a new one takes about ten minutes, no tools (usually), and may require a simple reducer bushing. Let’s do it!


Step 1

Check the diameter of the PVC pipe going into your old sump pump and mark it down somewhere.

Step 2

Go buy a sump pump.

Okay it’s not that easy, check the diameter of the discharge port. If it’s a different size, you’ll need a bushing to connect the two. My pipe was 1.25”, however my new sump pump discharge port was 1.5” so I needed a 1.5 to 1.25” reducer bushing (https://amzn.to/3gHYa26 – although you can get it cheaper at Home Depot).

So, go buy a sump pump and a reducer bushing if you need it.

Step 3

Unplug the old Sump Pump, disconnect from the discharge line and remove from the basin.

Step 4

Place the new sump pump into the basin and make sure it’s level (if necessary, use some plastic shims to help out here).

Step 5

If needed, insert the reducer bushing into the discharge port, then reconnect the discharge line.

Step 6

Plug into a GFCI outlet (your old one should have been plugged into one, if it’s not a GFCI outlet, you should consider updating it).

And that’s it! You should have a fully functioning, NEW, sump pump.

Now take that extra $200 you saved on the plumber and go treat yoself to something fancy.
