A sump pump’s basin, or sump pit, usually holds approximately 15-30 gallons of water. It’s important to note that the pump’s actual pumping capacity is a different number, though. Other things that must be taken into consideration include pump water inflow, plus the needed lift.
In this article, Benjamin Franklin of Melbourne, FL, will explore how much rainwater an individual sump pump can handle. We’ll also provide key details to help you determine what size pump is right for your home.
Breaking Down Water Capacity
There are three different factors that must be taken into account when talking about total capacity of a sump pump. Below, we’ll take a closer look at each factor.
The Sump Pit’s Capacity
Standard residential sump pits generally range from 18 to 24 inches in diameter. A 24-inch basin equals approximately 2 gallons of rainwater for each inch. Meanwhile, an 18-inch basin typically equals 1 gallon per inch.
A Pump’s Active Working Volume
Each pump has a float switch to detect the amount of rainwater inside the pit. Generally speaking, the float switch triggers a reaction once it comes within 8-10 inches of the pit’s top.
From there, the pump should automatically drain down to approximately 2-3 inches of water, instead. That way, there remains enough water to serve as the motor’s lubricating pool.
Total Pumping Capacity
The volume of rainwater moved by the pump works differently from the sump pit capacity. This number is usually expressed in gallons per minute (GPM), although it’s occasionally measured in gallons per hour (GPH). Either way, it helps you judge whether or not your pump is appropriate for your specific area.
Let’s say you’ve got a standard 1/3 HP pump. Your pump should be able to accommodate between 30 to 35 gallons each minute.
How Does Lift Affect Sump Pumps?
The average amount of lift needed for a residential home is seven to 10 feet. Either can be handled by a standard 1/3 HP pump. Keep in mind, though, that the shorter the lift, the more quickly it removes excess rainwater.
Melbourne’s Flood Risk
Per FirstStreet.org, almost 5,400 residential and commercial properties in Melbourne have a moderate risk of flooding. Two previous hurricanes have caused significant flooding in parts of the city, too.
In total, 17.6% of Melbourne’s properties may flood within the next 30 years. While this might seem like a problem that won’t affect you, it’s vital to remember that these properties could flood anywhere from 1 day to 30 years from now. Therefore, taking action now could save your property from extensive flood damage.
What Pump Size Do I Need in Melbourne?
The answer to this question depends on the soil composition, your pump’s capacity, and the local water table, along with the size of your property. However, instances where it rains between one and two inches per hour will start testing the limits of most residential systems.
One way to keep your property safer is to install a water-powered or battery-powered backup system. It’s also wise to replace your main sump pump every 10 years.
Selecting a Small Tank
If you live outside of the flood area for Melbourne, you might be able to get away with installing a small tank. A small tank manages minimal water inflow. They can work well when you have limited space and a small house, but only if you don’t live in a flood area. Alternatively they can be paired with a french drain around your home for extra protection.
Choosing a Medium Tank
Choosing a medium-sized tank instead of a small one offers a compromise between cost and performance. Medium tanks typically hold between 18 and 30 gallons.
Basically, this means your pump should be able to handle most sudden and large increases in inflow. At the same time, it won’t have the more exorbitant pricing of a larger tank.
For homes located outside of Melbourne’s flood area, these tanks can work quite well. They’re not as robust as a large tank, but they’re definitely workable in areas where it typically doesn’t flood.
Picking a Large Tank
A large tank requires a larger upfront investment and requires more space. At the same time, it’ll provide peace of mind and will keep your property safer during any major rain events.
Large tanks accommodate 30 gallons or more. This reduces the number of necessary cycles during heavy rain, which extends its lifespan. They also have a much more considerable buffer to deal with intense rain.
If you live in Melbourne’s flood area, you may want to consider choosing a large tank. They work especially well in areas with a high water table. Additionally, they can generally handle sudden heavy rainfall.
