When the plumbing system is not working correctly, wastewater will not flush down toilets as normal. The backflow could seep out of the fixtures and onto the bathroom flooring. Water damage repair and odor removal technicians will need to restore the bathroom to its former condition. So you can take steps to prevent this headache, below are common causes of toilet backflow.

What Are Some Reasons for Toilet Backflow?

1. Backflow Preventer

Pipes connecting toilets to the wastewater disposal system have backflow preventers. Similar to gates, these valves allow water to flow down toilet drains but will block off the channels to prevent the liquid from coming back up. If a valve breaks, toilet sewage will flow back through the drain even when the fixture isn’t being used.

2. Sewer Line 

Sewer lines can corrode and break down over time. This can make it difficult for wastewater to flow from house toilets to the city’s sewer system. Invasive tree roots can also clog the channels and force sewage to change course.

As main sewer lines are often installed under building foundations, you might notice backflow in basement drains before it pools in toilets. To avoid the need for water damage repair, call a plumber as soon as you notice an issue in the cellar.

3. Municipal Services

If the backflow preventer and sewer lines are intact, toilet backflow might stem from an issue with municipal services. Problems with city sanitation equipment can alter normal operation. Toilet backflow might be a side effect of the problem.
