Water in your basement

Reduce sewer or drain losses in your basement by checking drainage, reducing backflow and installing a sump pump.

Sump pump drainage system

No one wants to experience sewer backups in the home.

Like many questions around home maintenance, when it comes to sewer problems, prevention is the best solution. Considering how much damage can be caused by water in your basement, it makes sense to spend a little time testing out your drainage system and addressing any problems before a catastrophe occurs.

Here are a few easy ways to keep your basement clean and dry.

Make sure your drainage system works

Often, water in your home comes down to preventable drainage problems. A few hours of work could keep the water out. Review this checklist to help:

  • Your home's gutter downspouts should extend at least 10 feet away from the foundation of the house so water is carried away from basement walls.
  • Clear your gutters at least twice a year to prevent them from overflowing. Leaves and debris will clog gutters and can send water back toward your roof, walls or foundation.
  • Gutters and downspouts should not be connected to municipal sewage lines.
  • Your yard should be graded to slope away from the house so surface water is drained away.
  • If your gutters connect to storm sewers, keep drain lines clear.

Prevent backflow

Backflow is the reversal of water in any plumbing system. It can lead to undesirable leaking and flooding.

Some homes are equipped with check valve devices that allow water and sewage to flow away from the drain, preventing water and sewage from backing up into the drain. Gate-valve devices operate like a gate, closing and shutting off the flow of water and sewage.

Drain plugs and standpipes can also be used to prevent backflow. Both are relatively inexpensive solutions, but also come with their own risks. Drain plugs seal off the flow of water but can cause an overflow to occur at the next opening in the system. Standpipes, or vertical pipes connected and sealed to a drain, can contain minor overflows and act as safety valves, but can only contain backflow up to their height, usually just three feet.

If you think you're having problems with backflow, contact a plumber or contractor immediately.

Sump pumps

Sump pumps are pumps that remove water from a reservoir in your home.

There are several types of sump pumps, including single sump pumps and dual-level systems, which employ a backup pump. Usually, batteries or a generator can be used to power the pump in case of a power failure.

If you'd like to get a sump pump for your home, check with your local plumbing contractor or building code official for additional requirements.

When all else fails

Sometimes water still gets in even when you take precautions. If it does, here are a few things you can do to minimize damage:

  • Keep items stored in basement areas shelved or off the floor. Consider replacing cardboard boxes with sturdy containers for storage.
  • Place furniture on casters or shims and arranged away from floor drains.
Check with your local building code department, water utility or a qualified plumber for more information on steps you can take to reduce the chance of water damage to your home. And talk to your local insurance agent to see what’s covered in your homeowners policy.
