Basement flooding is a potentially grave issue. Many negative consequences are associated with it, which causes disruption and mess beyond control. Frequent basement floods can cause damage to building as well as un-insured equipment.

There may be a rise in insurance rates and premiums due to repetitive basement flooding claims. Basement prone to regular flooding can experience depreciation in property value.

Causes of basement flooding

Water occurrence in the basement is due to rapid melting of snow or heavy rainfall. However, in some cases it is due to –

  • Poor drainage
  • Crack or leak in basement walls
  • Overflowing eaves trough
  • Failure of foundation drains
  • Leaking downspouts
  • Blocked connection between main sewer and home
  • Backup of sewer system’s waste water
  • Failure of sump pump

Public sewer network is handled by municipalities, but homeowners need to maintain their private sewage system regularly. Basement flooding is linked with sewer system. Combined sewer systems can cause basement issues, when they backup, especially during major storm.

Private sewer system is prone, when sump pump fails. Separated sewer systems in new developments are least risky. Sometimes tree roots or blockages in pipe connected to house and sanitary sewer causes backup issues.

When sewer gets overloaded, water level rises over normal levels. This condition is called ‘surcharge’. If home has floor drains or sanitary fixtures below surcharge level basement flooding occurs.

How to avoid basement flooding?

  • Eaves troughs & downspouts

Water flows from eaves troughs into downspouts. If downspouts dump besides foundation wall, then it drains directly to weeping tile. This can overload the drainage, and so to avoid this extend downspouts, at least 6 feet away from basement wall towards street, back lane or rear yard. Clean debris regularly from the eaves troughs. If they brim over, even when they are clean, just replace the eaves troughs and downspouts with large ones.

  • Lot grading

The build up land around your house needs to be high and water needs to be drained away from basement walls. Overtime ground settles and lot slopes inward. Therefore, check the driveways, patios, sidewalks, and decks regularly.

  • Install flood proofing devices

To prevent sewage backup due to neighborhood drainage system overloads install a couple of flood proofing devices like –

  • Sump-pit drainage system
  • Back water valve
  • Regular maintenance

Have professionals from Absolute Draining & Plumbing Services inspect plumbing fixtures and flood proofing devices regularly. It gives peace of mind that everything is operating properly.
