Usually, submersible sump pumps are the best choice, but they’re not created equally. You have to consider the pumping capacity and sump pump size to ensure that it works for your house.

Do I Need a 1/3 or 1/2 HP Sump Pump?

Usually, 1/3 HP motor power is enough. However, if you live in a flood-prone area, you may choose 1/2 or even 3/4 HP. To be safe, consider one that overperforms. That higher pumping capacity will keep you going in all situations.

How Do I Know What Size Sump Pump I Need?

The first step is to decide between a submersible and a pedestal pump. Then, you have to figure out how many gallons per hour you require and make sure your system can handle that.

Some homeowners have a primary pump and backup pumps with drainage connected to each. That means they’re protected if there’s a significant amount of rainfall or the water rose too quickly on a rainy day.

Is a 1/2 HP Sump Pump Too Much?

If your home has an above-average water table, you will probably need the 1/2 HP pump. It pumps roughly 35 to 40 percent more water than the 1/3 HP pedestal pumps.

Generally, if the water rises higher than normal, the 1/3 HP version can handle a high vertical lift whenever it’s discharging water. However, a 1/2 HP pump can tackle 7 to 10 feet higher, even if there’s a 90-degree elbow and the horizontal pipe runs 3 to 25 feet.

Can Sump Pumps Be Too Powerful?

Yes, pedestal and submersible pumps could be too powerful. They may stop and start frequently, leading to premature failure over time.
