Pedestal Sump Pump vs Submersible Sump Pump

As a homeowner, what should you pay attention to when it comes to your water system? How about the fact that a properly designed and installed water conditioning system will extend the life of your water pipes, save money on repairs, remove bad tastes and odors from your water, and even improve its quality? That’s what a properly designed and installed water conditioning system will do. But, there are several different types of water conditioning systems on the market, and many homeowners get confused by all the options. That’s why I’m going to explain the differences between a “pedestal sump pump” and a “submersible.”

What is a “sump pump”?

It’s a device that sits on the bottom of your basement floor (or wherever else your water might seep) and uses a mechanical force to move water up into an elevated tank. Then, the water flows through filters and other purification devices and is finally pumped back down into your plumbing system. This method is extremely effective at removing large quantities of water from a small area, but it has some serious drawbacks:

  • First of all, sump pumps are very noisy—sometimes they can be heard in blocks.
  • They also require a fairly constant source of electricity, which means you’ll have to keep a 110-volt AC power cord plugged into the electrical outlet in your basement or another damp area.
  • Also, because sump pumps are mechanical, they eventually need to be replaced. When that happens, you’ll need a plumber.
  • And finally, because sump pumps are mechanical, they can and do break down from time to time.

What is a submersible sump pump?

submersible sump pumpAs the name suggests a submersible sump pump is a small pump that is placed at the bottom of your sump pit or drains pan. When activated, it forces water out of the bottom of the pit and up through an external hose to a level above the pump. This prevents the water from building up in your basement and possibly causing structural damage.

A submersible sump pump is an automatic device that discharges water from your basement into a container, thus allowing it to be removed through a drainage system. This prevents your basement from becoming flooded and also keeps the water from damaging your home’s foundation. This type of pump is crucial to ensure proper drainage in areas with clay or sandy soil. In dry soil conditions, your home might become vulnerable to flooding.


  • It will keep you from drowning in floods.
  • It works when it’s cold out.
  • It won’t freeze your home’s water pipes.
  • It’s silent.
  • You can put it outside or inside.
  • You don’t have to dig a hole.
  • It works with almost any style of home.
  • You can put it in a closet.
  • It’s compact and small.
  • You can put it on a countertop.


  • Must be run continuously and is not easily repaired if it stops working.
  • Must be able to withstand extremely high pressures.
  • Must be relatively trouble-free.
  • Usually requires a significant amount of maintenance.
  • Submersible pumps are much more difficult to repair than surface pumps.
  • It can cause a dangerous buildup of pressure and damage the pump.
  • It needs to be serviced periodically.
  • It is more expensive than other types of pumps.

What is a pedestal sump pump?

pedestal sump pumpA pedestal sump pump is a kind of deep good pump used for pumping water out of an area with low groundwater levels. They are often used in buildings or homes with sloping or flat roofs. The reason they are called pedestal pumps is that they are usually placed on a pedestal, and hence have a higher center of gravity than conventional sump pumps.

A pedestal sump pump is a type of submersible pump, which means it is designed to work in water. These pumps are typically placed on a wooden or metal pedestal and connected to an electrical outlet or a battery-operated DC motor. When activated, they send water up through an intake valve, and out through a check valve into a drainage system.

How pedestal sump pump work?

A pedestal sump pump has a metal or plastic box with a piston-like plunger inside of it. As water is pumped into the box, the piston gets depressed, creating a partial vacuum that sucks the water out of the building via the plumbing system. The water then flows to a sump pit below the building where it is collected and disposed of. A submersible sump pump works exactly the same way, except that it has a suction hose instead of a plunger-like device. The water is sucked out of the building through the hose and into the sump pit.


  • Pedestal pumps are easier to install and maintain.
  • They can be removed from your water line at any time if you need to access the waterline.
  • The pump is installed on the ground, which makes it less likely to be affected by flooding.
  • Because the pump is on the ground, it’s easier to install.
  • The pump is attached to a hose that leads to the nearest storm drain, so you can direct the water where it needs to go.
  • You don’t have to worry about putting a hose in the ground to direct water into a rain barrel or other container.
  • Because the pump is on the ground, it’s easier to connect to an existing storm drain.
  • They’re more cost-effective than their submersible counterparts.
  • They’re also easier to clean and repair.


  • It takes up space.
  • It is too large for the room.
  • It drains slowly.
  • It needs to be turned off to drain properly.
  • The pump will drain when the floor is dry.
  • You need to use a hose to direct the water away from the pump.
  • Water does not go into the sump pump; it only goes out.
  • It is expensive.
  • It must be turned off while cleaning.

Difference Between pedestal sump pump and submersible

The main difference between a pedestal sump pump and a submersible pump is the mounting type. A pedestal sump pump is mounted on a concrete foundation, which allows it to withstand heavy loading, as well as high water pressure. A submersible pump, on the other hand, is directly connected to the water line and is usually located below the waterline, which makes it much safer and more efficient to install.

Side-by-Side Comparison pedestal sump pump and submersible

pedestal sump pump  submersible sump pump
The pedestal is for small drains like laundry tubs, bathrooms, and utility rooms. The submersible pump is for larger drains like sinks and bathtubs.
A pedestal pump is installed below grade level and is powered by a separate electrical source. A submersible pump is installed at grade level and connected to the main building’s electrical supply.
Higher power consumption Lower power consumption
Use larger motor and may provide more pressure. Use a smaller motor and may provide less pressure.
A pedestal sump pump is a pump with a motor and impeller located below the water level. A submersible pump is a pump with a motor and impeller located above the water level.
The pedestal pump sits on top of the slab. It is designed to be placed under the slab.
It has multiple intakes and outlets. Features a single intake and discharge.
Highly reliable. Less reliable.
Easier to install and maintain. Complicated to install and maintain.
Pedestal sump pumps are less expensive. More expensive than a pedestal sump pump.
