The Quick Answer
Most plumbing problems give you a window to act before they become catastrophic. The difference between a $200 repair and a $15,000 restoration project is almost always time — specifically, how long a warning sign was noticed but not addressed. This guide covers the 10 plumbing problems Michigan homeowners most commonly wait on, why each one escalates, and exactly what to do when you spot them.
There’s a very human tendency to hope a plumbing problem will resolve itself or at least stay manageable until it becomes convenient to deal with. Sometimes that works. More often — especially with the 10 problems in this guide — waiting turns a repair into a restoration project, and a restoration project into a nightmare.
This isn’t about fear. It’s about understanding which problems compound quickly and which ones give you more time, so you can make informed decisions about when to pick up the phone.

The 10 Plumbing Warning Signs You Should Never Wait On
💧 An Unexplained Spike in Your Water Bill
A water bill that doubles or triples without a change in household behavior is a reliable indicator of a continuous hidden leak — a running toilet, a slow pipe leak, or an underground line leak. At 200+ gallons per day wasted, the financial meter is running constantly. Beyond the water cost, if the leak is inside the walls or under the foundation, ongoing moisture is actively causing structural damage and creating mold conditions. The City of Grand Rapids offers a one-time bill adjustment for confirmed leaks, but only with documentation of a completed repair.
What to do: Perform the water meter test (turn off all water, check if meter is still moving). See our full guide.
🟤 Any Water Stain on a Ceiling or Wall
A water stain on a ceiling or wall represents a leak that has already occurred — and usually one that has been occurring for some time. By the time the stain is visible, the drywall, insulation, and potentially the structural framing have already absorbed significant moisture. Left unaddressed, mold colonizes within 24–48 hours of sustained moisture. A discolored patch that is soft, bubbled, or actively growing means the source is still active and the damage accumulation is ongoing. In Michigan, where basements mean multiple stories of water can migrate downward, a second-floor bathroom leak can reach the first floor and basement before it’s obvious.
What to do: Do not paint over it. Identify whether the stain is new or growing (trace the outline with a pencil and date it). If it’s growing, call Kenowa Plumbing for leak detection immediately.
📉 Low Water Pressure Throughout the Whole House
A single fixture with low pressure usually indicates a localized issue — a clogged aerator or a partially closed shutoff. Whole-house low pressure is different and more serious. It can indicate: a partially closed or failing main shutoff valve, a pressure regulator failure, significant scale buildup inside supply lines (common in West Michigan’s hard water), or — most urgently — an active leak on the service line between the street meter and the house. The last scenario means water is escaping underground, and the pressure drop is the only signal you’ll get before the yard becomes a swamp or the water utility notices abnormal usage.
What to do: First, confirm all shutoff valves are fully open. Check with a neighbor to rule out a municipal pressure issue. If the issue persists, call Kenowa Plumbing for a pressure test and leak assessment.
💨 Sewage or Rotten-Egg Smell Indoors
Sewage odors inside a home indicate sewer gas is entering through a failed trap, a cracked sewer line, or an improperly vented drain. Sewer gas is not just unpleasant — it contains hydrogen sulfide (toxic at sustained exposure levels) and methane (flammable and asphyxiating in high concentrations). Brief odors after a toilet flush are normal; persistent odors from floor drains, shower drains, or anywhere in the house without an obvious cause warrant immediate investigation. Dry floor drain traps (common in Michigan basements that see infrequent use) are a simple fix; cracked sewer lines are not.
What to do: Pour water into all floor drains and infrequently used fixtures to refill dry traps. If the smell persists, it is not a dry trap — call Kenowa Plumbing for sewer line assessment.
🔄 Gurgling Drains or Toilets
Gurgling from a drain while another fixture is used — a toilet that gurgles when the washing machine drains, or a floor drain that gurgles during a shower — indicates partial blockage or venting failure on the main sewer line. This is the sound of air being pulled through the system as water tries to drain past a narrowing. It is a warning, not just an annoyance: a partial blockage becomes a full blockage, and a full blockage becomes a sewage backup. In Michigan basements, a sewer backup is a serious water damage and health event.
What to do: Do not use drain cleaning chemicals — they rarely address main line blockages and can damage pipes. Schedule a drain cleaning and sewer camera inspection with Kenowa Plumbing before it backs up fully.
🟠 Discolored Water (Brown, Yellow, or Rusty)
Brown or rusty water at the tap has two main causes: corrosion inside aging galvanized pipes, or sediment stirred up in the water heater. Either warrants prompt attention. Corroding galvanized pipes are leaching rust (iron oxide) into your water — and pipe walls that are corroding on the inside are also thinning from the outside, moving toward failure. A water heater producing rusty water has a failing anode rod and a tank interior that may be near the end of its serviceable life. Ignore this long enough and the heater fails and floods the utility room.
What to do: Run cold water at the tap for 2–3 minutes. If rust appears only when running hot, the water heater is the likely source — call Kenowa Plumbing for an assessment. If cold water is also discolored, the issue is in your supply pipes.
🔥 Water Pooling Around the Water Heater
Any water visible around the base of a tank water heater signals an active issue that needs same-day attention. Possible causes: the T&P relief valve is discharging (the tank is overheating or over-pressurizing — a safety concern), a supply line connection is leaking, or the tank itself has begun to fail and is seeping through a corroded section. A seeping tank that is not addressed will rupture — releasing the entire tank volume (40–80 gallons) onto your utility room floor. In finished basement utility rooms, this means flooring, walls, and stored belongings.
What to do: Do not ignore it and hope it dries up. Turn off the cold water supply to the heater. If the T&P discharge pipe is actively draining, do not cap it — that valve is protecting you. Call Kenowa Plumbing for same-day assessment.
👂 Running Water Sound with Nothing On
The sound of running or dripping water when all fixtures are off and the household is quiet is one of the clearest plumbing distress signals. It most commonly indicates a running toilet (the flapper is allowing water to constantly refill the bowl — silent from across the house but audible in a quiet moment), a slab leak (water running beneath the foundation floor), or an active pipe leak inside a wall. Each of these compounds: the running toilet wastes hundreds of gallons per day, the slab leak erodes the foundation over time, and the wall leak destroys building materials and creates mold conditions.
What to do: Check all toilets first (dye test). If no toilet is the source, perform the water meter test. If the meter is moving with all water off, call Kenowa Plumbing for professional leak detection.
🍄 Mold or Mildew Near Plumbing Fixtures
Mold visible at the base of a toilet, under a sink cabinet, around the shower base, or on a wall near a fixture is almost always a symptom of a slow, sustained moisture source — a failing wax ring, a slow supply line drip, or a cracked shower pan. Mold around a plumbing fixture is not a cleaning problem; it is a leak problem that will continue until the moisture source is eliminated. In Michigan, where summer humidity accelerates mold growth, a small slow drip can create an extensive mold colony inside a wall cavity within weeks.
What to do: Clean the visible mold and monitor whether it returns. If it returns within a week or two, there is an active moisture source that must be found and fixed before any remediation is meaningful.
🚿 Significantly Reduced Hot Water Supply
If your hot water runs out noticeably faster than it used to, or hot water arrives much more slowly at fixtures, there are two likely causes: sediment buildup in the water heater tank (reducing the effective heating volume and efficiency — a direct result of West Michigan’s hard water), or a failing heating element or gas burner assembly. Either condition means the heater is working harder to deliver less. An efficiency-compromised heater runs longer cycles, uses more energy, and is approaching the end of its service life. Addressing it proactively is almost always cheaper than emergency same-day water heater replacement.
What to do: Have Kenowa Plumbing flush the water heater to remove sediment. If the heater is 8+ years old and still underperforming after a flush, start planning for replacement rather than waiting for a failure.

Frequently Asked Questions
A true plumbing emergency — one that warrants an after-hours call — involves active water flowing where it shouldn’t be (burst pipe, flooding), no water at all to the house, sewage backing up into living spaces, or a gas smell. Everything else can typically wait for the next available business hours appointment, though ‘wait’ means scheduling promptly — not indefinitely.
If there’s an active leak, shut off the nearest isolation valve to that fixture or the whole-house main shutoff if needed. Document the problem with photos or video before the plumber arrives — this helps with insurance claims and gives the plumber useful context. Move valuables away from the affected area. Do not attempt to open walls or fixtures unless you have plumbing experience.
Coverage depends heavily on the nature and cause of the damage. Sudden and accidental damage (a pipe bursts without warning) is typically covered. Damage from a slow leak that was present for weeks or months — and that you reasonably should have noticed — is often excluded as a maintenance failure. This is another reason why acting quickly on warning signs matters: it strengthens your insurance position if damage has already occurred.
