What is a Sump Pump?
Sump pumps are pumps used for drainage that removes accumulated water
from a sump pit or other location inside your home. A sump pit, commonly
found in the home basement, is simply a hole dug in the ground to collect
water. The water may enter through drains that have been funneling into
the pit over time, especially during inclement weather.
Use of A Sump Pump
Sump pumps are installed particularly where basement flooding is seen
as a problem, but are also used to improve dampness by lowering the water
table under the foundation. Sump pumps pipe water away from the house
to any place where it no longer presents a hazard, such as a municipal
storm drain or dry well.
Types of Sump Pumps
There are two available categories of sump pumps, Automatic and Manual.
An automatic sump pump has a switch attached that activates the pump when
the water reaches a certain height and turns the pump off when the sump
pump has drained the water.
A manual sump pump must be turned on and off manually. Sump pumps may
also have battery backups, control panels, and automatic switches amongst
other accessories installed to ensure continuous and proper operation.
Parts of A Sump Pump
- Groundwater Collection System - Routes excessive groundwater to a
- Sump Basin - Basin that collects liquid for removal.
- Primary Sump Pump - ¼ HP to 1 HP, submersible or pedestal.
- Discharge Pipe/Hose - An open valve or pipe run that carries discharge
water away from the home.
- Check Valve - Prevents backflow through discharge outlet so that water
pumped out of the basin does not flow back into it when the sump pump
- Backup Sump Pump System (Optional) - Can provide added protection
in the event of a power failure or if your primary pump fails.
Selecting a Sump Pump
When it comes to choosing the right sump pump for your home, you will
need to know the full uses for it. To select the appropriate sump pump
consider the following:
- Automatic vs. Manual Operation: Selection of a manual sump pump means
that you will turn the pump on and off when appropriate. Selecting an
automatic sump pump means that a switch is wired to the sump pump to
turn it on or off at appropriate water levels. Automatic switches include
pressure switches, low level pressure switches and float switches.
- Horsepower: Sump pump horsepower will vary from 1/4 horsepower to
- Cord Length: The cord length of a sump pump describes the length
of the power cord. It is also important to consider the length of the
cord of any special switches that may be connected to your pump.
- Phase & Voltage: The voltages offered include 115, 230, and 460
- Backup System & Alarm: If redundancy and an alert system are
vital for operation of your sump pump, consider a backup system and/or
alarm to alert you when things go awry.
