Let’s be honest, common toilet problems are the worst. If you’re at home or running a business, nothing throws off your day like a toilet that won’t flush or keeps running for hours. It’s one of those things you don’t think much about… until it stops working.
At Hard Knox Plumbing, we handle toilet repair in Knoxville all the time. And no issue is too small (or too messy) for us to help with. Here’s what you should know about the most frequent toilet problems, and when to call a pro.
1. Running Toilet
That constant sound of running water? It’s not just annoying, it’s wasting gallons every day. Most of the time, a running toilet means the flapper isn’t sealing properly, the chain’s too tight, or the fill valve is worn out.
According to the EPA, a running toilet can waste up to 200 gallons of water daily. That’s money literally going down the drain.
2. Weak Flush or Partial Flush
You hit the handle, but it barely flushes. Sometimes the water just swirls around without doing much.
Why it happens:
- The water level in the tank is too low
- The flapper closes too quickly
- The rim jets are clogged
3. Toilet Won’t Flush at All
Now we’re in full panic mode. You press the handle and nothing happens.
Possible causes:
- The chain connecting the handle to the flapper is broken or disconnected
- The flapper is stuck
- There’s a clog in the trap or drain line
If adjusting the chain doesn’t help, and a plunger doesn’t clear it, it is time to call someone who knows how to fix it like Hard Knox Plumbing.
4. Leaky Toilet
Leaks can show up around the base, tank, or water supply line. You might not notice right away, but water on the floor or a musty smell are signs.
Most common causes:
- A worn wax ring under the toilet
- Loose tank bolts
- Cracked tank or bowl
Tip: Don’t ignore a small leak. It can damage your floors and subfloor fast, and mold might follow.
5. Constant Clogs
Sure, every toilet clogs now and then. But if it’s happening weekly (or daily), that’s not normal.
What might be going on:
- Low-flow toilet with weak flush power
- Buildup or partial blockage in the pipes
- Tree roots invading the sewer line
You might need professional drain cleaning or even a camera inspection to figure out what’s really happening.
DIY Fixes You Can Try
We always say: If you’re comfortable lifting the lid on the tank and replacing a part, go for it. But don’t risk turning a small fix into a costly repair.
Here’s what’s usually safe:
- Replacing a worn flapper
- Adjusting the chain or water level
- Using a plunger carefully (don’t use too much force!)
Avoid this: Pouring chemical drain cleaners into your toilet. These can eat through your pipes over time.

Frequently Asked Questions: Toilet Problems in Knoxville Homes and Businesses
- Why does my toilet make a loud noise after flushing?
That noise is usually caused by “water hammer,” which happens when water suddenly stops or changes direction in your pipes. Installing a water hammer arrestor can help. - Can I use bleach tablets in the toilet tank?
It’s not recommended. Bleach tablets can break down rubber components like flappers and seals, causing leaks and damage over time. Stick to gentle, non-corrosive cleaners. - What causes a toilet to smell even after cleaning?
Persistent odors might be coming from a bad wax ring seal or sewer gas leaks. If you notice smells that don’t go away, it’s best to have a plumber inspect the base and drain. - How long should a toilet last before needing replacement?
Most toilets last 15 to 25 years, but if you’re dealing with constant repairs or high water usage, it might be worth upgrading to a newer, more efficient model. - Is it okay to flush “flushable” wipes?
No. Even though packaging says they’re flushable, they often don’t break down fast enough and can cause clogs in pipes and sewer systems. Toss them in the trash instead.
