A slow drain seems minor. A toilet that gurgles can sound like nothing more than a strange house noise. A small drip through a ceiling may look like a job for a handyman.
Those are exactly the kinds of signs homeowners can put off until the problem becomes harder to ignore.
In a recent Hire It Done episode, Adam Helfman spoke with Travis Haines and Nathan Bourdon of Nelson Haines Plumbing and Drain Cleaning about the signals a plumbing system gives before a bigger problem develops. Travis has more than 20 years in the trade, and the company has been around for more than 50 years.
The useful lesson for homeowners is simple: your plumbing usually gives you clues. The sooner you understand what those clues can mean, the sooner you can decide whether you are dealing with routine maintenance, a developing clog, or an issue that deserves professional attention.
1. A Slow Drain Keeps Coming Back
A bathroom sink that drains slowly is often the first sign of a local clog. In the episode, Travis explained that soap and hair are common causes.
That sounds simple, but the way you respond matters.
Many homeowners reach for a bottle of chemical drain cleaner because it is fast and easy. Nathan cautioned against drain acids, especially when a home has cast-iron or older piping. He also pointed out the skin-safety risk of handling strong chemicals.
The important question is not just, “Can I make the water go down today?”
It is, “Why is this drain slowing down, and am I fixing the cause?”
If a slow drain keeps returning, a plumber can clean the line and help determine whether the issue is a basic local clog or part of a larger drainage problem.
2. A Basement Drain Bubbles After Heavy Rain
Water showing up around a basement floor drain deserves more attention than a slow bathroom sink.
Adam described a scenario where heavy rain is followed by water filling a basement floor drain and starting to bubble upward. Nathan’s advice was immediate: stop running water in the house and call a plumber, especially if the backup is happening at night or getting worse.
That step matters because continuing to run fixtures can add more water to a system that is already struggling to drain.
A professional may clear the line and then use a drain camera to see what is happening inside. The blockage could involve buildup, tree roots, or a problem with the pipe itself.
If water is coming up instead of going down, treat that as a warning sign, not an inconvenience.
3. Brown, Smelly Water Comes Up Through a Drain
Not every backup is the same.
Travis explained that clear water in a basement may point toward rainwater, while brown, foul-smelling water can indicate sanitary sewer water coming back up.
That distinction changes the urgency and the way the area should be handled.
If you see dirty or foul-smelling water coming through a floor drain, avoid treating it like a normal puddle. Stop using water where practical and get professional help to identify the source and restore proper flow.
The goal is not just to remove the visible water. You want to understand why it came back into the home and what needs to be cleaned, cleared, repaired, or inspected before normal use resumes.
4. Your Toilet Gurgles When You Flush
A gurgle is easy to ignore because the toilet may still flush.
In the episode, Adam asked what a “bloop, bloop, bloop” sound can mean. Nathan said it may be a sign of a clog somewhere in the main line. They also discussed the possibility of a blocked vent stack.
That is why unusual plumbing sounds are worth noticing.
A drain system needs both proper flow and proper venting. When air and water are not moving the way they should, you may hear noises before you see a complete backup.
One odd sound does not automatically tell you the exact repair you need. It does tell you to pay attention, especially if the gurgling is new, repeated, or happening along with slow drains.
5. Water Drips Through a Ceiling Below a Bathroom
This is one of the clearest signs that waiting can make the situation worse.
Adam described water dripping through a kitchen ceiling or light fixture with a bathroom directly above it. Nathan said the plumbing team sees situations like that regularly.
The first job is diagnosis. A plumber may inspect the wet drywall, check for an access panel behind the tub or shower, and open drywall when necessary to find the leak.
The visible drip is not always directly below the source. Adam noted that water can travel horizontally before it finally finds a place to come through the ceiling.
That is why guessing from the stain alone can waste time.
If the leak is active, the priority is to stop the source, identify the failed plumbing connection or drain, and prevent more water from spreading. Drywall and paint repairs come after the plumbing problem is under control.
6. You Need to Double-Flush More Often
A toilet that regularly needs two flushes may be telling you something has changed.
When Adam asked whether repeated double-flushing could indicate a problem, Nathan agreed that there could be an issue worth checking.
Sometimes the toilet itself may be part of the problem. In other situations, installation details can matter.
The episode also covered toilet flanges and the common shortcut of stacking two wax rings when a flange sits too low after a new floor is installed. Travis warned that a double wax ring may get someone out of a bind, but it can still lead to a leak later. He recommended bringing the flange to the proper level instead of relying on the shortcut.
The broader lesson is useful: when a fixture stops performing the way it used to, do not assume the symptom is normal just because it still works.
7. Your Home Uses Water When Nobody Should Be Using It
Some plumbing leaks are obvious. Others can happen while you are at work or away from home.
Travis recommended a whole-home leak detector with an automatic water shutoff. Adam explained how these systems can monitor water flow, send an alert when usage suddenly changes, and shut off the water automatically.
That kind of prevention is especially useful for homeowners who travel, own a second home, or simply want another layer of protection when nobody is watching the house.
A leak detector does not replace maintenance or a plumber. It can give you earlier information and, depending on the system, help limit how long water keeps running after a problem starts.
What Should You Do When You Notice a Warning Sign?
Start with the symptom you can actually observe.
Is one sink slow, or are several fixtures acting differently? Is a toilet gurgling? Is water coming up through a floor drain? Is there an active ceiling leak? Has a fixture suddenly started behaving differently?
Then avoid making the problem harder to diagnose.
Do not keep running water into a backed-up system. Be cautious with strong chemical drain cleaners, especially in older plumbing. If water is actively leaking, focus on stopping or isolating the source as quickly as you safely can.
When a plumber arrives, diagnosis should come before a major repair recommendation. Nelson Haines discussed using cameras to see where a clog is, what is blocking the line, and whether a pipe is damaged. That information helps determine whether cleaning, snaking, hydro jetting, repair, or another approach makes sense.
A good service call should leave you with a clearer understanding of what is happening in your home and why the recommended next step fits the problem.
Listen to What Your Plumbing Is Telling You
Homes do not come with a dashboard light that says “check plumbing.”
The warning signs are slower and less obvious: a drain that takes longer than it used to, a toilet that gurgles, water where it should not be, or a fixture that suddenly needs extra effort to work.
Those signs do not all mean the same thing, but they are worth noticing.
As Adam put it during the episode, your house is always giving you information. Paying attention early gives you a better chance to handle a plumbing problem before it becomes an emergency.
If you are dealing with repeated clogs, backups, leaks, or unusual plumbing noises, document what you are seeing and call a qualified plumber who can diagnose the system before recommending the fix.
