Toilet Troubleshooting: Common Issues and Fixes
Your toilet is one of the most used fixtures in your home, and when it stops working properly, it can quickly become a major inconvenience. A toilet that won’t flush, constantly runs, or clogs frequently can disrupt your daily routine and even lead to costly water waste or plumbing repairs.
At Downey Plumbing, we’ve seen just about every toilet problem there is, from simple fixes to full-blown plumbing disasters. While some toilet issues can be resolved with basic troubleshooting, others require professional repair to prevent further damage. Let’s go over some of the most common toilet problems, how to fix them, and when to call in an expert.
1. Toilet Won’t Flush Properly
Why It Happens
A toilet that won’t flush properly can be frustrating, and the cause isn’t always obvious. Some of the most common culprits include:
- A faulty flapper – If the rubber flapper inside the tank isn’t sealing correctly, water will continuously leak into the bowl, preventing a strong flush.
- Low water level in the tank – If there’s not enough water in the tank, there won’t be enough force to flush the toilet completely.
- A clogged drain – A partial blockage in the drain can slow down flushing and leave waste behind.
How to Fix It
First, check the flapper inside the toilet tank. If it looks worn or doesn’t sit flush against the flush valve, replacing it is a simple and inexpensive fix. Next, inspect the water level in the tank—it should be about an inch below the overflow tube. If it’s too low, adjust the float valve to allow more water in. If neither of these fixes work, try using a toilet plunger or a toilet auger to clear any potential clogs in the drain.
When to Call a Plumber: If your toilet continues to have weak flushes despite these fixes, there may be a deeper issue with the drain line or sewer system. Call Downey Plumbing at 562-646-1221 for a professional inspection.
2. Toilet Keeps Running
Why It Happens
A constantly running toilet can waste hundreds of gallons of water per day, driving up your utility bill. The most common reasons for this problem include:
- A worn-out or misaligned flapper – If the flapper isn’t sealing correctly, water will continuously leak into the bowl.
- A malfunctioning float valve – If the float is set too high, water will keep filling and spilling into the overflow tube.
- A leaky fill valve – A faulty fill valve may not shut off properly, allowing water to keep flowing into the tank.
How to Fix It
Start by inspecting the flapper in the tank. If it looks warped, brittle, or doesn’t sit properly, replacing it can usually stop the running water. If the issue is the float valve, adjust it so that the tank fills to the correct level without overflowing. If water is continuously leaking from the fill valve, replacing this component may be necessary.
When to Call a Plumber: If replacing the flapper and adjusting the float valve doesn’t stop the issue, there may be a deeper issue with the fill valve or the overall water pressure in your home. Contact Downey Plumbing at 562-646-1221 for expert repair.
3. Toilet is Clogged or Drains Slowly
Why It Happens
Clogs are one of the most common toilet problems, and they can happen for several reasons:
- Too much toilet paper – Flushing large amounts of toilet paper can overwhelm the drain.
- Non-flushable items – Items like wipes, paper towels, and hygiene products can quickly cause a blockage.
- Build-up in the drain line – Over time, mineral deposits and debris can narrow the pipe, making it more prone to clogs.
How to Fix It
A plunger is usually the first line of defense. Use firm, steady plunges to create suction and dislodge the clog. If that doesn’t work, try a toilet auger, which is a flexible snake-like tool that can break up blockages deeper in the drain. For slow-draining toilets, pouring hot water and dish soap into the bowl can help loosen debris.
When to Call a Plumber: If plunging and snaking don’t work or if your toilet keeps clogging frequently, it could indicate a bigger problem in your home’s plumbing system. Call Downey Plumbing at 562-646-1221 to prevent further damage.
4. Toilet Leaks at the Base
Why It Happens
A leaking toilet isn’t just an annoyance—it can lead to serious water damage and even structural problems if left unchecked. Common causes include:
- A worn-out wax ring – The wax seal between the toilet base and the floor can degrade over time, leading to leaks.
- Loose toilet bolts – If the bolts that secure the toilet to the floor are loose, water can escape from the base.
- Cracks in the toilet bowl – A hairline crack in the porcelain can cause slow, unnoticed leaks.
How to Fix It
If the leak is coming from the base of the toilet, check the mounting bolts on either side of the toilet and gently tighten them. If this doesn’t stop the leak, the wax ring may need to be replaced, which involves removing the toilet and installing a new seal. If the porcelain is cracked, the only real solution is replacing the toilet entirely.
When to Call a Plumber: If you’re unsure how to remove and reseal the toilet or if you suspect a crack in the bowl, let a professional handle it. Contact Downey Plumbing at 562-646-1221 for leak repairs.
Preventing Future Toilet Problems
While toilet issues can be frustrating, regular maintenance and mindful use can help prevent many common problems. Here are a few tips:
- Only flush toilet paper and waste – Avoid flushing anything that isn’t meant to go down the toilet.
- Inspect the tank components annually – Check the flapper, fill valve, and float to ensure everything is in working order.
- Fix leaks immediately – A small leak can turn into a big problem if left unchecked.
- Use a moderate amount of toilet paper – Excess paper can lead to frequent clogs.
- Schedule professional maintenance – A plumber can inspect your system for hidden issues before they become major problems.
