There’s nothing quite as frustrating (and potentially embarrassing) as a toilet that won’t flush away all your…well, crap. The good news? Most of the reasons your toilet won’t flush are common and can often be resolved with simple fixes. Today, we’ll walk you through the top culprits behind a non-flushing toilet and what you can do to get things flowing again.
Why Your Toilet Won’t Flush (and How to Fix It)
If your toilet won’t flush, the issue can stem from several places: the water valve, the flapper, the float, or even the rim jet itself. Let’s take a closer look at each of these reasons your toilet may not be flushing properly.
The Toilet Is Clogged
A clog is the most common reason a toilet won’t flush. Whether it’s the result of too much toilet paper, a flushed wipe, or an accidental drop of a toy or makeup item, toilet clogs block the drain and prevent waste from leaving the bowl.
You can often address a clogged toilet with a flanged plunger. Press down firmly, then pull up with enough force to loosen the clog. If this doesn’t work (or if you’ve misplaced your plunger), you can try a homemade solution. Pour hot (but not boiling) water and dish soap into the toilet to break up clogs. Avoid using chemical drain cleaners, as they can damage your plumbing over time.
If the clog is too stubborn, you will need to call your local plumber for assistance. They have access to professional tools like a drain snake and hydro-jetting machines to tackle even the most difficult blockages.
The Flapper Is Broken
The flapper is a rubber piece in your toilet tank that lifts when you flush, allowing water to flow into the bowl. If the flapper is damaged, worn, or not sealing properly, it can prevent your toilet from flushing efficiently.
Lift the lid on the tank to check the condition of the flapper. If it’s cracked or no longer fitting snugly, replace the flapper. (Replacement flappers are inexpensive and easy to install.) Once your new flapper is in place, test it out to make sure your toilet flushes properly.
The Chain Is Disconnected or Too Short
The chain connecting the toilet handle to the flapper can sometimes become disconnected or tangled. If the chain is too loose, it won’t lift the flapper enough to allow a full flush. If it’s too short, it might not let the flapper close completely.
To fix this problem, open the tank and inspect the chain. Reconnect it to the lever and adjust its length so it’s taut but not overly tight. Finally, test the flush handle for proper operation.
The Fill Valve Is Faulty
Toilets rely on gravity and water pressure to flush waste effectively, so if there’s not enough water in the tank, the flush won’t pack enough punch to clear the bowl. If your tank doesn’t have enough water, the fill valve, which controls how much water flows into the tank, is often the culprit.
To troubleshoot, remove the tank lid and inspect the fill valve. If it appears clogged or stuck, try cleaning it with a brush or replacing it entirely. Ensure the valve is adjusted to allow enough water to reach the fill line marked inside the tank. If you’re not comfortable performing this task yourself, ask the expert plumbers at Skagit Plumbing for help.
The Float Is Improperly Set
The float in your toilet tank controls the water level by rising and falling with the water. If it’s set too low, the tank won’t fill with enough water for a powerful flush. If it’s set too high, water can overflow into the tank’s overflow tube, wasting water and weakening the flush.
Check the float’s position and adjust it if necessary. For older toilets with ball floats, bend the arm slightly to change the water level. For newer models with cup floats, adjust the float height using the screw or clip mechanism. Ensuring the float is set at the right level will help your toilet flush properly.
The Rim Jets Are Blocked
The rim jets are small holes located under the rim of the toilet bowl that allow water to flow out during a flush. Over time, these jets can become clogged with mineral deposits, reducing water pressure and preventing the toilet from flushing.
To clean the rim jets, use a small brush, toothpick, or wire to remove debris or mineral buildup. For more stubborn deposits, soak the jets with a mixture of vinegar and water. Regular cleaning of the rim jets can improve water flow and restore your toilet’s flushing power.
