Toilet Repair 101: Fixing Common Toilet Problems

If your toilet sounds like a waterfall at 2 a.m., or it just won’t flush, you’re not alone. Toilet troubles can turn a normal day upside down. The good news? Most common problems have telltale symptoms—like a leaky tank or a stubborn clog—that you can spot early. But sometimes, a simple fix just won’t cut it.

At Alexanders Plumbing, we know how stressful home plumbing surprises can be. Whether you’re facing a quick drip or a full-blown emergency plumbing situation, our team helps get things back to normal—fast and safely.

Diagnosing Issues 🚽

Toilets are the workhorses of the home. When they act up, it’s usually for a reason you can see, hear, or even smell. Here’s how to read the signs:

• Constant Running: Hear a trickle or hiss long after flushing? Water is leaking from the tank to the bowl.
• Clogging: Water rising in the bowl, slow to drain, or not flushing at all? There’s likely a blockage in the trap or drain.
• Leaks: Puddles around the base or dripping from the tank? This could mean a cracked seal or loose hardware.
• Weak Flush: If the flush barely moves anything, you might have water pressure issues near you, a flapper problem, or mineral buildup.
• Phantom Flushes: The toilet refills randomly. Usually a slow leak from the tank.

Tip: Take a photo or video of the issue. This helps explain the problem if you call for help—or lets you remember what to check later.

Quick Safety Checklist

Before you grab the plunger or wrench, take a moment:

• Turn off the water supply at the shutoff valve behind the toilet.
• Keep the area dry. Slippery floors can lead to falls.
• Wear gloves if you’re working inside the tank or bowl.
• Never use chemical drain cleaners—they can damage pipes and are dangerous to skin and eyes.
• Unplug nearby electrical items, especially if there’s a leak.

Remember, safety first. If water is pooling near electrical outlets or you notice a sewer smell, call for emergency plumbing right away.

DIY Fixes for Common Toilet Problems 🛠️

Many toilet issues can be tackled with basic tools and a little patience. Here’s how:

Unclogging a Toilet

• Use a cup plunger (the kind with a flange) for the best seal.
• Place the plunger over the hole, push down gently, then pump vigorously.
• If water won’t move, try a toilet auger.

Fixing a Running Toilet

• Remove the tank lid. Check the flapper (the rubber seal at the bottom). If it’s warped or doesn’t seal, replace it.
• Adjust the float so the fill valve shuts off sooner.
• Tighten the chain if it’s too loose or tangled.

Repairing a Leak at the Base

• Tighten the tank bolts—gently.
• If water keeps pooling, the wax ring may need replacing. This usually means lifting the toilet, so when in doubt, call a professional.

Weak Flush Troubleshooting

• Check the rim holes under the bowl’s edge for mineral buildup. Clean with a wire or old toothbrush.
• Make sure the tank fills to the proper water line.

When to Call a Pro

Some problems are too serious—or risky—for DIY. Call Alexanders Plumbing if you notice:

• Persistent leaks that return after a quick fix.
• Cracked toilet bowl or tank. Cracks can lead to flooding or serious water damage.
• Repeated clogs or sewer smells. These hint at deeper drain or sewer line issues.
• Water at the base after storms. This could mean backflow or sump pump failure.
• Water running nonstop even after replacing parts.

Plumbing codes (like those from the International Association of Plumbing and Mechanical Officials) require licensed professionals for repairs involving gas lines, backflow prevention, and major pipe work.

Preventing Future Problems 🛡️

A little maintenance goes a long way. Here’s how to keep toilet troubles at bay:

• Check for leaks monthly: Add a few drops of food coloring to the tank. If color appears in the bowl after 10 minutes (without flushing), you’ve got a slow leak.
• Don’t flush anything but toilet paper. Wipes—even “flushable” ones—can clog pipes.
• Inspect the flapper and fill valve every 6 months. Replace worn parts.
• Keep a plunger handy. It’s your first line of defense.
• Schedule annual inspections for older homes or if you’ve had repeated issues.

The Environmental Protection Agency (EPA) recommends high-efficiency toilets to reduce water waste and prevent overflows.

Costs & Time Factors

Every repair is different, but here’s what to expect:

• DIY fixes: Unclogging or replacing a flapper can take 10–30 minutes.
• Professional repairs: Most jobs are wrapped up in under an hour, unless parts are needed.
• Major repairs: Cracked bowls, repiping, or sewer line work require more time and sometimes multiple visits.

Prices vary by job complexity and parts. Emergency plumbing visits may have after-hours fees.

When It’s an Emergency 🚨

Certain toilet issues just can’t wait. Call Alexanders Plumbing right away if:

• Water is flooding your bathroom.
• You smell sewage or gas near the toilet.
• The toilet is leaking from the tank or base onto electrical outlets or heating vents.
• Repeated backup after storms or heavy rain—this could mean a failing sewer line or backflow.

Quick action saves money and prevents bigger headaches down the road.

FAQ: Toilet Troubles

Q: Why does my toilet keep running?
A: Usually, it’s a worn flapper or a misadjusted float. Try replacing the flapper or checking the float arm.

Q: Can I use chemical drain cleaners?
A: No—these can corrode pipes and damage your plumbing system.

Q: How do I know if the wax ring needs replacing?
A: If you see water pooling at the base after every flush, the wax ring could be failing.

Q: What should I do if the bowl is cracked?
A: Stop using the toilet and call for professional repair immediately. Cracks can cause hidden leaks and water damage.

Local & Seasonal Considerations

In colder weather, pipes leading to and from the toilet can freeze—especially in older homes or poorly insulated bathrooms. During spring storms and flooding, sewer lines can back up, causing toilets to overflow. If you’re in a region with hard water, mineral buildup can cause weak flushes or clogs.

Annual plumbing inspections and winterizing exposed pipes can help. If you’re noticing recurring problems in a certain season, mention it when you call—timing can give clues to underlying issues.

Toilet problems don’t wait for a convenient time. Whether it’s 3 p.m. or 3 a.m., Alexanders Plumbing is ready for your emergency plumbing needs. Don’t let a small leak turn into a major headache.
