Is your toilet running? Creepy gurgling noise emitting from your toilet bowl? From water leakage to unusual noises, toilets can do all sorts of strange things.

Fortunately, with a little troubleshooting, there are many toilet issues you can fix on your own. Here, the professionals at Classic Air will go over some of the most frequent toilet problems, what they mean and whether it’s a situation you can fix yourself—or, if it is better to call in an expert.

1. Why Is My Toilet Running?

If your toilet won't stop running, it is a situation you should correct because it's in all probability also costing you money on your water bill.

A typical culprit that causes a running toilet is something wrong with the overflow tube. Found in the tank in the back of your toilet, an overflow tube removes extra water from the tank into your toilet bowl so the water level in your tank doesn't get too high and overflow the top of the tank. Sometimes, the issue is that the plastic tube connecting your fill valve to your overflow tube got detached. If that’s the situation, you should be able to reach into the tank and reattach them. It also may be your toilet is running due to the fact the overflow tube is too short for the water level and needs to be replaced by one that is taller height.

Another thing that could cause a toilet to run could be the flapper--which acts as a plug in the bottom of your tank—is damaged and no longer forms the tight seal required to hold water in the tank. Not having a good seal allows water to leak out the bottom of your tank into your toilet bowl.

Occasionally a running toilet is caused by something amiss with your toilet float, which is a floating device that controls the water level in your tank. It accomplishes this by shutting off your fill valve when the water level raises the float to a predetermined height. If your float is set too high, this lets the water level to rise too high, and the excess water will flow into your overflow tube and down into your toilet bowl.

2. Why Does My Toilet Keep Gurgling?

A gurgling toilet is usually caused by a partial blockage in your toilet, drain lines, mainline or an obstruction in your sewage vent. If the reason for the noise is a clog in your toilet, you can attempt to correct this by using a plunger or drain snake to loosen the clog. If this doesn’t work, you can examine where your sewage vent exits your home to confirm it is not blocked by debris that would restrict air flow.

If you've done these two trouble shooting tasks and the toilet is still gurgling or bubbling, you should call a professional such an expert from Classic Air to evaluate the problem. As the go-to plumber in Columbus, Classic Air will find out if the issue was caused by a blockage in one of the drain lines carrying toilet water out of your home or the mainline that takes waste water away from your home to the municipal water system.

4. Why Won't My Toilet Flush?

If you can’t flush your toilet, it's likely the problem is with the chain, flapper or the handle. That’s because there’s a chain inside the toilet tank that is hooked to the back side of the handle. The other end of the chain is linked to the flapper, which functions as a plug in the bottom of your toilet tank.

The best way to figure out why your toilet is hard to flush is to take off the lid, peer inside the tank and investigate.

Here’s how the process ought to work when you flush a toilet: you push down the handle, which pulls up the chain, then the chain pulls the flapper up and that enables the water to whoosh out of your tank and into your toilet bowl.

Sometimes a toilet won’t flush because the chain is snagged on something within the tank, which prevents the chain from pulling up the flapper to let out the water. Or, the chain is too long or becomes detached from either the handle or the flapper. If this happens, free the caught chain or reach in and change it to the appropriate length.

At times flappers can get stuck when they get old or become worn out. Or, there may be something amiss with the handle.

5. Why Is There a Leak in My Toilet?

A dripping toilet can be a costly problem, potentially producing water damage in and around your bathroom. Often, a leaky toilet is due to a cracked supply line or a crack in the toilet tank. If your toilet tank is overflowing, it could be a malfunction in the toilet float.

Cracked gaskets around the connections on the underside of the tank also can allow water to leak out of the toilet, as can a broken toilet flange or wax ring at the base of the toilet where it sits on the floor. Most of these issues are best fixed by a certified plumber. 

6. Why Is There No Water in My Toilet?

A toilet that isn't filling with water often traces back to a problem with the fill valve, which is the valve that lets water into your toilet tank. If the tube has failed or is plugged by rust, sediment or mineral buildup, it may not be allowing water into the tank.

Another common cause for your toilet not filling with water is something faulty with the float, which is a device that prompts the fill valve to stop bringing water into the tank when the water has risen to the correct level. The fill valve performs this function when the water level lifts the float to a set height. It might be that the float/float assembly needs adjustment so that the water can attain the correct level. Or, correcting a toilet not filling with water might require adjusting or exchanging the fill valve.
