Sewer Back Up FAQ’s Answered by Your Suburban Chicago Plumbing Experts

Ask The Plumbing_Banner1

Q: What are the three main causes of sewer back ups and how can they be prevented?

A: The three main causes are clogged lines, heavy rain, and human interference.

1. Clogged lines occur when waste, inorganic debris, paper products, grease, and even tree roots build up in your sewer line. The best way to prevent these clogs is to perform regular maintenance, or have one of our Lake Cook Plumbing professionals perform it for you.

2. Heavy rain causes a sewer back up to manifest in your basement, rather than outside of your home. Unfortunately, there’s nothing you can do to prevent the rain, but you can try and stay ahead of the flooding by hiring a professional to service your main lines. This way, you’ll be prepared for when the heavy rains come pouring down.

3. Human interference, much like the rain, can’t be predicted. But, it can be prevented. Some people will place unauthorized items in manholes that will clog your line up, but to stop them you can install gates and locks that will keep these people from accessing your lines.

Q: Is there anything else I can do to stop a backing up sewer in its tracks?

A: As a matter of fact, there is. There are a few devices you can get:

  1. Floor drain plug: Because most sewer back ups start in the floor drain, it’s handy to have one of these available. This plug seals off the drain and prevents liquid from passing through it.
  2. Standpipe: Though a standpipe is a cheaper alternative to a floor drain plug, it’s only useful for back ups that aren’t too serious. It allows water to enter through the drain, while still keeping it in the pipe.
  3. Overhead sewer: This device has an ejector pump that moves sewage out through an appropriate exit that leads away from all vulnerable areas of your property.
