Sump Pump Installation & Replacement
A sump pump is used for drainage collected water or to remove water that has accumulated in a pit, commonly found in a home's basement. The water may enter via the perimeter drains of a basement waterproofing system, funnelling into the pit or because of rain or natural ground water, if the basement is below the water table level.
Sump pumps are used where basement flooding happens regularly and to ameliorate dampness where the water table is above the foundation of a home. Sump pumps send water away from a house to any place where it is no longer problematic, such as a municipal stormdrain or a dry well.
Pumps may be connected to the sanitary sewer in older properties but now, this practice may be against the plumbing code or city bylaws because it can overwhelm the municipalsewage treatment system.
Usually hardwired into a home's electrical system, sump pumps may have a battery backup. The home's pressurized water supply powers some pumps, 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.
