How to Choose the Best Sump Pump

Choices that influence your life and that of the people you love are the hardest to make. And, even though it may not seem like it at first, sump pumps have the ability of changing one’s live, as they can be your only helping hand in case of flooding. Their importance goes from protecting one’s home against excessive humidity and limescale to saving hundreds or thousands of dollars as potential flooding damages.

Of course, before you can make a choice, you need to know the basics.

Basic Facts about Sump Pumps

There are two major types of sump pumps: pedestal (above ground) and submersible. Their power usually varies between 1/4 and 1 horsepower.

The pedestal pumps have their motors mounted on a shaft outside the sump basin. The vertical design is meant to allow easy access to the motor and simple adjustment for specific on/off points. These pumps are ideal for sump pits of 10 inches or less. They are economical and are able to operate between 5 and 15 years, but they require positioning in such a way as to avoid the submerging or the motor or getting it wet.

The submersible pumps on the other hand have their motor sealed in it's case and sunk to the bottom of the sump basin, meaning they are meant to be installed underwater. They are quieter and safer – thus more appropriate for families with children; they are perfect for installment in finished basements and are able to operate up to 25 – 30 years.

Both types of sump pump systems have six major components:

  • The sump basin – The sump basin is the pit that stores the water before the pump removes it. There is usually some amount of water in the basin and the pump won't be triggered to turn on until the water level reaches a certain height.
  • The primary pump – This is the main pump that will run to evacuate water out of the basin usually plumbed into PVC pipe that will discharge the water out into your yard.
  • The plumbing The schedule 40 PVC pipe that is connected to your pump and directs the water to it's exit point outside of your hourse.
  • A check valve – that is used to prevent the discharged water from flowing back into the basin. This makes sure that the water pushed up and out does not all fall right back in which would trigger the pump to run again over and over on an continuous loop.
  • A backup sump pump – An optional backup sump pump can be used in case your primary pump is not able to function. This could be because the primary pump or plumbing is broken, but more often it's because the home does not have power to run the main pump.
  • A float switch – Which is usually a floating ball that has a metal piece inside of it that will make contact to trigger the primary pump to turn on anytime the water level gets too high.

Aspects to Consider When Choosing a Sump Pump

Backup sump pumps can be powered by batteries or by municipal water pressure. They are connected to the primary pump and they turn on when the main pump fails. It is important to install a light or sound alert system if your backup does not already have one so that you can be alerted in case anything goes wrong with the main pump.

Although sump pumps powered by municipal water pressure are designed to work with limited water quantities, they can make an excellent choice for a small household or one placed in an area where heavy rainfall is not part of the ordinary.

Switch Types

  • Capacitive switches measure the water level with the help of a microprocessor and start the pump when the level of the water in the sump basin reaches a predetermined point. The good thing about them is that they have no mechanical parts that could wear out.
  • Vertical switches are devices that travel vertically in the sump basin and turn the pump on when the water reaches a certain level. They are mechanical and they cannot be adjusted. It is very important that the switch be installed in a 90 degrees angle with the incoming liquid.
  • Diaphragm switches turn the pump on and off based on the water pressure levels.

Pump Material

Since sump pumps are used in moist environments and even under water (submersible), it is very important that their parts be made of corrosion and water proof materials, such as stainless steel, bronze, or epoxy-coated cast irons, sometimes even thermoplastics can get the job done. This way you can be sure that your pump will be safe and ready to use for years to come.

Pump Capacity

You will find it measured in gallons/minute or gallons/hour. Keep in mind the height to which water should be lifted for removal, also known as head pressure and make sure the pump you buy has the power to lift water to that level. The general minimum lift is 10′.
