Causes of Main Drain Clog/Blockage


Homeowners must do regular maintenance of their main drain to prevent main drain blockage. Don’t take chances; you can avoid expensive, messy main drain backups using a preventive maintenance service before a problem occurs. In older homes, tree roots can enter into the sewer line and continue to grow, causing backups. Regular maintenance can help tackle such problems before they cause damage. It will also remove the buildup of scale, debris, rust or other harmful materials. You don’t want your main drain to get clogged at the wrong time simply because you ignored routine maintenance.

What are Some Common Problems?

  •  A clog can cause a drain backup, spilling raw sewage into your home and creating expensive cleanup and repair.
  •  Clogging can also cause your plumbing lines to drain slowly.
  •  A common problem often experienced in older homes is tree roots penetrating the sewer lines and causing blockage.
  •  Residues, such as grease, oil, fat, hair, food, mineral deposits, and other blockages, build up in the lines to cause clogging.

How will I Know I Have a Problem?

The easiest way to know if you have a problem is to look out for the following obvious signs:

  •  Gurgling sounds coming from your drains and toilets.
  •  Water pooling around, or backing up of drains and toilets.
  •  The raw sewage smell coming from your drains.

What can I Do to Prevent the Problem?

  • Avoid pouring fat and oil down the drain, as this accumulates over time and causes main drain clog blockage.
  •  Have your main drain snaked before it gets blocked and turns into a costly after hours service call.
  •  Have a camera put down your pipes to help you know what is going on. This can help to clear doubts and help you know when to snake your drain. You can also opt to pay a plumber to snake it from time to time.
  •  You can help keep the sewer in great shape by avoiding putting objects and feminine hygiene products down the toilet, as these cause problems later on.
  •  Have a regular maintenance schedule to have your sewer checked and snaked at least once every two years. On average, homes that ignore main drain maintenance after every two years often have their drain clogged by the third year. It is better to spend a few hundred dollars every few years than end up paying thousands of dollars in huge repair costs, and have sewage backing up into your home, spilling raw sewage into your home.

Homeowners must know what causes main drain clog blockage and consequently take preventive measures to ensure their main drain is operating efficiently throughout the year. While taking preventive measures on your own can be helpful, it does not guarantee that your drain will not clog. The wisest thing to do is to have regular maintenance performed to ensure your main drain is in good shape. Regular maintenance helps to identify a problem the causes of main drain backups, which can be expensive and messy. By spending a few hundred dollars every few years on maintenance, you can save yourself several thousands of dollars in costly plumbing repairs.
