Sump Pumps
A sump pump is a pump used to remove water that has accumulated in a sump pit. A sump pit, commonly found in the home basement, is simply a hole to collect water. The water may enter via the perimeter drains of a basement waterproofing system, funneling into the pit, or may arrive because of rain or because of natural ground water, if the basement is below the water table level.
How Sump Pumps Works
Sump pumps are installed particularly where basement flooding is seen as a problem, but are also used to ameliorate dampness where the water table is normally above the foundation of a home. Sump pumps send water away from a house to any place where it no longer presents a problem, such as a municipal storm drain or a dry well. Older properties may have their sump pumps connected to the sanitary sewer, but this is frowned upon now (and may be against the plumbing code) because it can overwhelm the municipal sewage treatment system. Sump pumps are usually hardwired into a home's electrical system, and may have a battery backup. Some even use the home's pressurized water supply to power the pump, eliminating the need for electricity. Since a sump pit may overflow if not constantly pumped, a backup system is important for cases when the main power is out for prolonged periods of time.
There are generally two types of sump pumps: pedestal and submersible. The pedestal pump's motor is mounted above the pit, where it is more easily serviced but also more conspicuous. The submersible pump is entirely mounted inside the pit, and is specially sealed to prevent electrical short circuits.
Maintenance for Sump Pumps
Sump tanks and sump pumps must be maintained. Typical recommendations suggest examining equipment every year. Pumps running frequently due to higher water table, water drainage, or weather conditions should be examined more frequently. Sump pumps, being highly mechanical, will fail eventually, which could lead to a flooded basement requiring costly repairs.
When examining a sump pump and cleaning it, dirt, gravel, sand, and other debris should be removed to increase efficiency and extend the life of the pump. These obstructions can also decrease the pump's ability to drain the sump, and can allow the sump to overflow. The check valve can also jam from the debris.
