Is your sump pump snoring when it’s pouring? Or making other strange noises? Or worse – not working? If so, you need to purchase and install a new sump pump before you are greeted with a flooded basement. Here is some advice.
Pedestal or Submersible?
There are two types of sump pumps: pedestal and submersible.
Pedestal Sump Pumps
Pedestal sump pumps sit on a pedestal above the sump basin. These are generally preferred because they do a better job performing the main function of preventing flooding since they have a stronger motor.
Other advantages include:
- They last longer (15-20 years).
- They are easier to maintain and repair.
- They have a higher pumping capacity.
Disadvantages:
- They require preventative maintenance to grease bearings.
- They are more expensive (but this can be offset by longer life and the reduced risk of expensive flooding).
Submersible Sump Pumps
Submersible sump pumps are installed underwater in the sump pump pit. Some people prefer them because of the following reasons:
- They can be used in areas with limited space.
- They require little maintenance.
- They are less expensive
Some of the disadvantages include:
- The main one is they do not do as good a job as pedestal pumps of preventing flooding.
- They do not last as long (up to 10 years).
Note: if you are purchasing a submersible pump, make sure to buy one with a cast iron core and not a plastic one. Cast iron will help dissipate heat and can make the pump last longer.
Pumping Capacity
The pumping capacity is the number of gallons of water per minute (GPM) the pump can empty from the pit. The pumping capacity you need depends on the type of soil on your property as well as the amount of water that enters the pit during heavy rains. A professional plumber can advise you on the required capacity for your home when you install a new sump pump.
Horsepower
You want to purchase and install a new sump pump with the right amount of horsepower. Too little horsepower and the pump cannot do its job. Too much could waste energy and money and could shorten the lifespan of the pump. Pedestal pumps usually come with 1/3 to 1 horsepower; submersible pump horsepower ranges from 1/3 to 1/2 horsepower.
Other Considerations
- Install a new sump pump with a mechanical switch as opposed to a pressure switch.
- The float should be solid so it cannot fail to turn off, become waterlogged, or burn out the pump.
- The pump should have a screen intake design with an impeller that can handle solids up to ½ inch in diameter.
- Purchase a pump with an alarm to alert you when the water reaches a certain level.
- A “nice to have” is a “smart” sump pump that can alert you to problems when you are not home.
- And of course, make sure you also have a battery back up in case you lose power.
