Plug Drains To Prevent Sewer Backup

Plug Drains to Keep Sewage Backup Out

NDSU has information on plugging drains to keep sewage backup out.

Be prepared to plug your drains this spring to prevent sewer backup if you live in an area prone to flooding or heavy rain.

Raw sewage not only can damage building components and carpeting; it also has high concentrations of pathogens that can pose serious health risks.

Prevent Sewage Backup

To reduce the possibility of sewage backing into a home, homeowners need to seal areas where sewage can flow in during periods of excessive rains or flooding. Sewage not only can damage building components and carpeting, it also has high concentrations of bacteria, protozoans and other pathogens that can pose serious health risks. Water will seek the lowest level, so if the level of sewage or floodwater is higher than the drains in the home, such as those in the basement, a backup can occur.

Deciding if and when you should plug your drains depends on a variety of factors. For example, you should follow local officials’ recommendations on when to plug drains in the lower levels of your home. You also should plug your lower-level drains if you plan to evacuate because of the potential for flooding.

You may choose not to plug your drains if you have a newer home. Many new homes have anti-backflow or backwater check valves that should prevent sewage from backing up into the home. However, some of these valves have failed in flood situations, so you must decide if you want the added protection of plugging drains.

If you do not have a check valve, most hardware or home improvement stores carry a variety of plugs to fit different types of drains.

But do not wait until flooding is imminent to attempt to obtain plugs because they may not be available, or you may have situations in your home where a standard plug won’t work.

Backflow contamination can have hazardous or even fatal results. It is essential that backflow prevention programs be put in place and maintained on an ongoing basis. Stop Backflow news presents many case histories outlining the effects of backflow contamination.

  1. I never knew that there was such thing as a backwater valve and that it could help keep your drains from getting infected. I live in an older home with a very old septic system. Although we haven’t had backup, we’ve been seriously thinking about what to if there was. I’ll share this with my family. Do you have any tips for hiring a plumber to help us with this?
