Does your toilet keep running? Creepy gurgling noise coming from your toilet bowl? From water leakages to unusual noises, toilets can do all sorts of strange things.

Fortunately, with a little troubleshooting, there are many toilet issues you can fix by yourself. Here, the specialists at GLR Mechanical will go over some of the most common toilet problems, what they mean and whether it’s a plumbing issue you can fix yourself—or, if it is better to call in an expert.

1. Why Won't My Toilet Stop Running?

If your toilet won't stop running, it is something you should repair because it's most likely also costing you money on your water bill.

A frequent cause of a running toilet is something incorrect with the overflow tube. Located in the tank in the back of your toilet, an overflow tube directs excess water from the tank into your toilet bowl so the water level in your tank does not get too high and overflow the top of the tank. Sometimes, the problem is that the plastic tube connecting your fill valve to your overflow tube has become detached. If that’s the situation, you can reach into the tank and reattach them. It also could be your toilet is running simply because the overflow tube is isn't tall enough for the water level and needs to be replaced by one that is taller height.

Another reason for a toilet to run could be the flapper--which serves as a plug in the bottom of your tank—has malfunctioned and no longer forms the tight seal necessary to hold water in the tank. This enables water to seep through or around the damaged flapper and flow 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 determines the water level in your tank. It does this by shutting off your fill valve when the water level raises the float to the appropriate height. If your float is set too high, this lets the water level to rise too high, and the unwanted water will go in your overflow tube and down into your toilet bowl.

2. Why Does My Toilet Keep Gurgling?

A gurgling toilet is commonly caused by a partial blockage in your toilet, drain lines, mainline or something blocking your sewage vent. If the reason for the noise is a clog in your toilet, you can try to fix this by using a plunger or drain snake to loosen the clog. If this does not have any effect, you can check where your sewage vent exits your home to ensure 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 will probably want to phone a professional such an expert from GLR Mechanical to evaluate the problem. As the experienced plumber in Wilkes Barre and Scranton, GLR Mechanical 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 removes 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, there’s a good chance the problem can be found in the chain, flapper or the handle. That’s because there’s a chain within the toilet tank that is hooked to the back side of the handle. The other end of the chain is connected to the flapper, which serves as a plug in the bottom of your toilet tank.

The easiest way to figure out why your toilet is hard to flush is to lift up the lid, look 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 in the tank, which prevents the chain from yanking 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, unhook the caught chain or reach in and shorten it to the appropriate length.

Sometimes flappers can get stuck as they age or become worn out. It's also possible there may be something awry with the handle.

5. What Is Causing My Toilet To Leak?

A dripping toilet can be a costly situation, potentially producing water damage in and around your bathroom. Often, a leaky toilet is the result of a cracked supply line or a crack in the toilet tank. If your toilet tank is overflowing, it is often because there is something wrong with the toilet float.

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

6. Why Is My Toilet Not Filling with Water?

A toilet not filling with water often indicates a problem with the fill valve, which fills the tank in the back of your toilet with water. If the tube is damaged or is plugged by rust, sediment or mineral buildup, it might not be allowing water into the tank.

Another typical cause for your toilet not filling with water is something wrong with the float, which is a device that prompts the fill valve to stop bringing water into the tank when the water has gotten to the correct level. The fill valve does this when the water level lifts the float to a predetermined height. It might be that the float/float assembly needs adjustment so that the water can attain the correct level. Or, fixing a toilet not filling with water might require adjusting or exchanging the fill valve.
