Sump Pump Installation Guide. What Is a Sump Pump? If you're wondering whether you need this pump in your house, here are some of the reasons to buy a sump pump: Reduce the risk of flooding: During heavy rainstorms, flooding could occur if water leaks into your basement or crawl space.
Since a sump pump controls the flow of water away from the foundation of your home, your property won't suffer from short-term or long-term water damage. As a result, a sump pump also improves the indoor air quality in your living space by getting rid of excess humidity. Prevent the growth of mold and mildew: Stagnant water in your basement encourages mold and mildew to grow.
These fungi could cause structural damage in the wooden features of your home, along with allergies and respiratory problems in your family members.
When sump pumps remove standing water in your basement, mildew and mold are less likely to form in your living space. Keep away insects and other pests: Excess moisture wears out the wooden joists and walls within the frame of your property.
When wood rots, it attracts termites, ants and rodents, which all bring contaminants and unpleasant odors into your living space. Removing the standing water with a sump pump will reduce your risk of pest infestations. Limits the chance of fire or electrical damage: Water and electrical appliances don't mix. If the wires to your washer, dryer or other electrical appliances get wet, they could cause a power outage or even a fire in extreme cases.
Reduce your risk of damage to your property by preventing water from flooding in your basement or crawl space. Factors to Consider When Choosing a Home Sump Pump When selecting the best sump pump for your house, you should consider a few factors.
