Harpers Ferry Plumbing Guide: How to Stop a Toilet from Overflowing

An overflowing toilet is a really unpleasant problem to have in your Harpers Ferry home, and one you will undoubtedly want to correct right away. Toilets are reliable in that they tend to last a long time and not act up much, but when yours does start to malfunction, you pay attention right away.

To start with, examine the root cause of the overflow problem. There are three major causes of overflow: a clogged or blocked drain that does not allow the toilet to flush properly, an improperly adjusted float that allows the tank to overfill and a blocked vent pipe that replaces the air in the pipe after each flush.

Each of these requires a different course of action, so let’s discuss each individually.

If the drain is blocked, you will probably know right away. For one, water will overflow from the toilet’s bowl rather than the tank. For another, there will probably be quite a mess. Treating this type of overflow problem is straightforward—remove the clog. For simple clogs, a plunger and some elbow grease will get it done. Another trick is to stick the open mouth of an empty two liter bottle into the drain and squeeze. The blast of air can knock the clog free.

If your toilet is clogging and overflowing frequently, however, the problem may not be with the drain or with anything you are doing. It may be that the vent pipe is clogged. A vent pipe moves external into the plumbing system to replace the air that is pumped out with each flush. When it is blocked, the toilet can’t flush properly, which can lead to overflowing. If you have trouble with frequent clogging, call a Harpers Ferry plumber to inspect the situation.

In both of those situations, the toilet bowl will overflow. Another possibility is that the tank overflows, which is a different kind of problem. This is often cause by the filler float being set too high, so the tank fills with too much water. You can fix this by simply adjusting the mechanism inside the tank that controls the level of the float.

Whether it’s one of these three, or something else entirely, when your toilet overflows, be sure to check it out and get it fixed right away.
