Best Submersible Sump Pump | Sizing

Wondering what’s the best submersible sump pump size for your home? Good question! A lot of my readers ask the same thing. It’s important to buy the correct size pump for your basement because if you don’t have enough HP on your submersible sump pump, you’ll run the risk of flooding. And if you have too much HP on your pump, you’re wasting money on power you just don’t need.

Here's a good video first, then I include some homeowner tips.

This short video will give you some good information about to properly size your sump pump in your basement:

Replacing an Existing Submersible Sump Pump

If you’re replacing an existing basement sump pump here’s some easy advice to follow, in order to choose the best submersible sump pump for your basement.

Before your pump broke or died – was it doing the job for you? Did it keep up with rising water and prevent flooding?  As long as your old submersible sump pump wasn’t constantly running without shutting off, and it kept up with the demand, you should go with the same HP size for your new pump.

All you need to do is look on the service plate on the side of your old sump pump to see what HP rating it had. And just match that HP rating to your new submersible sump pump. This is an easy way to be sure you’re choosing the best submersible sump pump.

If you’re installing a submersible sump pump in your home for the first time, you’ll need to take a look at the gallons per hour and discharge height rating on each pump model. Every sump pump manufacturer provides a flow rate chart that shows you the maximum GPH (Gallons per Hour) capacity and height for each pump model.

It might help you to know that 1/3 hp and ½ hp are two of the most common horsepower ratings for submersible sump pumps sold to homeowners.

And this video, below, will show you how you can install a sump pump in your new home:


Advantages of Submersible Sump Pumps

Wondering what are the advantages of submersible sump pumps?

Here is a short list of the advantages of submersible sump pumps:

1.  Submersible sump pumps have quieter operation

2.  They’re hidden beneath your basement floor so they won’t get damaged by foot traffic, kids or pets

3.   Submersible sump pumps are usually more powerful (more HP) than pedestal pumps

4.   And submersible pumps generally have higher GPH discharge rates – so they pump faster

Yes, these are the four top advantages of submersible sump pumps and that’s why they’re such popular choices with homeowners.

There are some distinct advantages of submersible sump pumps that should be taken into account when you’re trying to choose between a submersible vs pedestal pump.
