Sump Pump Information
If you have already lived through the dreaded experience of a flooded
basement, then you know how much damage it can cause. Even one inch of water
can take many hours to clean up and causes thousands of dollars in damaged
furniture and carpets. Installing a sump pump in your basement is your best
defense to prevent flooding.
Basement flooding is most often caused by water
build up in the soil that makes its way into your basement. There are many
ways for water to enter and many ways to prevent it from entering. A sump
pump on the other hand is a last defense against flooding because it pumps
out water from the lowest section of the basement before the water level
reaches the basement floor level. As groundwater level rises it is diverted
into the sump hole. When the water reaches what is called 'the critical
level', the sump pump begins to pump it out through a pipe that leads outside
and away from your foundation.
Apart from the obvious damages to your belongings, flooding can also cause
plumbing problems, a damaged foundation or rotted wood; all of which are
troubles that bring down the value of your home. A sump pump can save you
thousands of dollars in the long run by maintaining the value of your home
and by protecting your belongings from water damage.
The sump pump has recently become more important especially in newer homes
since the Federal Clean Water Act no longer allows builders in many
municipalities to drain rainwater collected by gutters into sewerage systems.
Water collected on the roof of your home and drained by your gutters can
cause flooding if it is not carried carried far enough away from your
Types Of Sump Pumps
The two basic sump pump models are the up-right (commonly
called a pedestal) and the submersible. Either will work well with proper
maintenance. The pedestal pump has the motor on top of the pedestal and the
pump at the base, which sits on the bottom of the sump. The motor is not
meant to get wet. The pump is turned on and off by a ball float. One
advantage of this type of pump is that the on/off switch is visible so the
action of the ball float can be easily seen.
Submersible pumps are designed to be submerged in water and sit on the bottom
of the sump. The on/off switch is attached to the pump and can be either a
ball float connected to an internal pressure switch or a sealed, adjustable,
mercury-activated float switch. The sealed mercury switch is generally more
reliable than the pressure switch.
Either type of pump should have a check valve on the water outlet pipe so
water doesn't flow back in the sump when the pump shuts off. Water flowing
back and forth can cause the pump to turn on and off more frequently than
necessary and decrease the life of the pump.
