Sump pumps in New Bedford are small horsepower pumps that are installed in basements of homes. The sump pump is positioned in the very lowest part of the house and its job is to pump out water which accumulates under the basement slab, thus keeping the basement dry and free from flooding.

The sump pump is installed in a specially prepared pit; water gets to the sump pit via drains that were laid prior to pouring the slab or the water migrates to the pit through the base, usually crushed stone and sand. As the pit fills with water, the sump pumps motor is energized and the water is pumped out of the pit.

For many years, sump pumps in New Bedford were always installed in homes that were built in low lying areas. In the late 1980s the clean water act made sump pimps a requirement in all homes, regardless of the risk of flooding.

The basics of a sump pump system:

A sump pit is usually about 18 inches square and two feet deep. The pit is located in the lowest part of the basement. The base of the pit is a layer of gravel. The sump pump sits in the pit, the pumping mechanism is deep in the bottom of the pit, and the drive motor sits above floor line. The motor and the centrifugal pump are joined by a shaft.

As the water rises in the sump pit, a float mechanism or a pressure sensor turns the motor on. The pump begins to suck the water from the pit, discharging it through a pipe to the outside of the home. The pipe that is used for discharge has a check valve in it to stop water from running back into the pit.

Choosing a sump pump:

sump pumps New Bedford – are either submersible or pedestal type. Both types are about three feet in total length. The submersible design is actually in the water, encased in a waterproof housing. The pump is at the bottom, the discharge pipe is at the top. The pump sits on a screen that stops it from sucking up small stones and debris.

The pedestal type of sump pump is common. The pedestal keeps the pump and motor put of the sump pit. The pump sits at the top of the pedestal, which basically is a long pipe which sucks the water out of the pit. As the equipment is not in the water, the pedestal pump is noisier but because the motor does not have to be waterproof, the system is less expensive.

There are a number of options for sump pumps in New Bedford; horsepower, manual or automatic, head pressure etc. It is recommended that a professional select and install the pump for maximum efficiency.
