A toilet that refuses to flush isn’t just an inconvenience—it can be a headache that disrupts your daily routine. Below, we discuss the common causes behind this frustrating issue and some simple solutions. When you’re having plumbing troubles in Glendale, AZ, or the surrounding areas, give Don Jones Plumbing a call.

What Are The Common Causes of a Non-Flushing Toilet?

One of the most frequent culprits is a clog. Over time, debris like excessive toilet paper, sanitary products, or even small objects accidentally dropped into the bowl can block the passage, preventing proper flushing. Sometimes, the clog isn’t in the toilet itself but in the drain line further down, causing a partial or complete backup.

Another common issue is a malfunctioning flapper. This rubber valve in the toilet tank controls the release of water into the bowl. If it’s worn, misaligned, or doesn’t seal properly, it can prevent the tank from releasing enough water for a full flush. Similarly, problems with the fill valve, which controls water flow into the tank, can result in low water levels. Without sufficient water, the flush won’t have the force needed to clear the bowl.

Additionally, a broken or disconnected chain that links the flush handle to the flapper can be the culprit. If the chain is too loose or too tight, it may not lift the flapper effectively when you push the handle.

What You Can Do About It

Start by checking the toilet tank. Lift the lid and observe if the flapper is sealing correctly. If it appears worn or misaligned, replacing it is a simple and affordable fix. Next, ensure the chain has the proper slack—not so tight that it holds the flapper open, and not so loose that it fails to pull it up.

If the water level in the tank is low, adjust the fill valve to ensure it fills to the appropriate level (usually marked inside the tank). A low water level can drastically reduce the flushing power.

For clogs, try using a plunger or a toilet auger. Often, a few vigorous pumps will dislodge the blockage. However, if the clog persists or if multiple fixtures in your home are backing up, it might be time to call a professional to inspect your drain lines.
