# **Common Reasons for Sewer & Drain Pipe Issues**

Your sanitary sewer and drain lines may already be damaged by tree roots, cracks, line sagging, or offset connections before you experience complete sewer line failure. Do not let your sanitary system get to the point were it fails! A failed or collapsed sanitary sewer line will cost you thousands more to repair than proactive maintenance will. To ensure you have everything you need to prevent problems with your drains, please read the following information featuring the five most common reasons for a typical deteriorating sewer system presented by our company.

 

| ## ![leaking-pipe](https://www.calgarysewerscope.ca/hs-fs/hubfs/leaking-pipe.jpg?width=255&name=leaking-pipe.jpg) ## Reason 1: Junction Collapse A junction or joint collapse occurs when a section falls into the pipe. This will create major problems in the main sewer line as well as the house connection. | ## ![blocked-pipe](https://www.calgarysewerscope.ca/hs-fs/hubfs/blocked-pipe.jpg?width=248&name=blocked-pipe.jpg) ## Reason 2: Tree Root Penetration Tree interference into your sewer systems is a huge problem and can be extremely costly, as ongoing work may be required to keep the roots in check. In Calgary, root penetration into sewer pipe systems is reported to cause 50% of all sewer blockages, and is likely to occur in older systems and cracked pipes. | ## ![collapsed-pipe-1](https://www.calgarysewerscope.ca/hs-fs/hubfs/collapsed-pipe-1.jpg?width=243&name=collapsed-pipe-1.jpg) ## Reason 3: Collapsed Main Line A collapsed main line is not an uncommon problem — it can happen for several reasons. This type of failure creates openings in the pipe and is a major cause of root infiltration. It may also cause significant ground contamination and pollution of the surrounding waterways. |
| --- | --- | --- |
| ## Reason 4: Main Sewer Line Cracking It is recommended to replace or repair the pipe as soon as you detect cracking to avoid bigger leaks. Cracking can lead to a main line collapse, increasing the cost of repair significantly for the homeowner or business. | ## Reason 5: Offset Joints or Connections Offset joints or connections can occur due to ground settlement, landslide, tree roots, and poor compaction during installation. This can cause damage and weakness to the main line and potentially generate massive leaks. |   |
