The best sump pump
Unless it's flowing through your pipes to a sink, shower, toilet, or washing machine, you don't want water coming into your house. A sump pump is a device that allows you to remove any groundwater that's seeping into your home before it can create a breeding ground for mold and cause permanent damage to your home.
The best sump pump is the one that meets your specific pumping needs. Our favorite is the Wayne 1/2 HP Primary and Battery Backup Combination Sump Pump System, a reliable sump pump system that helps keep your home safe and dry, even when you lose power. To learn about the three critical elements you need to consider when selecting that perfect sump pump, keep reading.
Considerations when choosing sump pumps
There are two main types of sump pumps to consider when shopping: pedestal and submersible. Each type has its pros and cons, and you must carefully weigh them to determine which is best for your particular situation.
Pedestal sump pump
Like it sounds, a pedestal sump pump is a long slender device with a motor that sits atop a pedestal. The motor is not designed to become wet, so it must stay well-above the water line. Because of that feature, it's only appropriate for shallow sump pits. It runs louder, but it tends to last longer and is priced lower than a comparable submersible sump pump. The biggest downside is that pedestal sump pumps cannot easily handle particles that may wind up in the water.
Submersible sump pump
A submersible sump pump is positioned deep in the sump pit, so it's underwater. The location makes it quieter, and its design is better suited for handling solids and small debris. The downside is that the best models can cost significantly more than pedestal sump pumps, and often they don't last as long.
Gallons per minute
After deciding on the type of sump pump that's best suited to your needs, you'll want to find the one that can handle the job. In other words, how much water can it move? If it can't pump out the water quickly enough, it's not going to be of much use.
Gallons per minute (GPM) is the unit of measurement that sump pumps use. About 40 or 50 gallons per minute is more than sufficient for average home use. However, that measurement also must include the height the water needs to be in order to be pumped out of your basement, which is typically 10 feet. You must be careful because some manufacturers may list the specs in a confusing way. For instance, a pump that can move 2,100 gallons per hour sounds impressive, but it really only moves 35 GPM. Additionally, if that rating is with a zero head or lift, when calculating a 10-foot lift, the pump's flow rate will be even less. As long as you understand what to look for, you won't be fooled.
At the lower end of the price scale, you can purchase a light-duty plastic submersible sump pump for about $50 or $60. The decent mid-range sump pumps, either pedestal or submersible, are available in the $80 to about $170 price range. If you're looking for a heavy-duty cast iron submersible sump pump with battery backup, those models can range from $200 to more than $500.
Q. Does a sump pump turn on automatically?
A. Yes, in most instances it does. You can override this feature, but then you run the risk of having the water level rise significantly, enough to flood your basement.
Q. Why is my sump pump running constantly, even when there is no water to pump?
A. If you have a sump pump with a float switch, it could be stuck in the "on" position. If you run a sump pump when there is no water, it can cause your pump to burn out prematurely.
Sump pumps we recommend

Our take: A powerful top-of-the-line sump pump system that is designed to protect your home even if the power fails.

Our take: A durable thermoplastic submersible sump pump that is manufactured to deliver many years of reliable service.
