Sump pumps are generally installed in specially constructed sump pits. Water flows into the sump pit through drains or by natural water migration through the soil. The sump pump's job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry.
Sump pumps are used where basement flooding happens regularly and to solve 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 storm drain or a dry well.
A sump pump eliminates moisture and prevents flooding. Even if your basement doesn't flood, basement moisture can lead to mold and potential health problems. If you own a home and live in an area susceptible to excessive snow or rainfall, a sump pump is your best bet.
The nature of sump pumps means they're never going to smell like perfume, and unusually pungent odors often indicate you need plumbing services. Sump pump odors are usually early warning signs of a problem.
sump pumps don't last forever. With an average life expectancy of about 10 years, your pump could just be acting up because it's time for a replacement. In most cases, sump pumps should be tested every three to four months. This should involve opening the inlet screen and cleaning it out, among other things. In some cases, your sump pump might actually benefit from more regular cleanings.
