What Causes Toilet Overflow?

Schedule Online

No homeowner wants to deal with an overflowing toilet. Not only is it inconvenient, but it can also be costly, especially if the backed-up wastewater seeps into the other rooms in your home. As your go-to expert in sewer repair in Mesa, AZ, Zippity Split Plumbing will help you fix the problem before it causes a disaster. To help you take preventive measures, it pays to know what causes toilets to overflow to ensure it doesn’t happen again.

1. Blocked Vent Pipe

If your toilet clogs often, chances are something is blocking the vent pipe. Vent pipes move pressure into your plumbing system to replace the air you need to pump in every flush. When the vents get blocked, your toilet will fail to flush properly and start to overflow. In this case, get drain and sewer repair services to address the issue.

2. High Filler Float

When your filler float is set too high, too much water will fill the tanks and leak from the sides. Our sewer pipe line repair experts can fix the problem by adjusting the mechanism inside the toilet tank to keep the filler float at proper levels.

3. Blocked Sewer Lines

There are cases when the problem lies deep in your sewer lines. Debris buildup, congealed grease, and tree roots can block your underground pipes, causing wastewater to back up into your toilet and other drains in your home. Worse, your sewer line might have already collapsed. Depending on the extent of the issue, we may need to repair or even replace sewer line.
