Toilet overflowing right now? Take the tank lid off and push the flapper down to stop water entering the bowl, then close the shutoff valve behind the toilet by turning it clockwise.
What Your Toilet Is Doing, and What It Means
Most of these are small parts rather than a new toilet. The right-hand column is the honest answer about which is which.
| What you notice | Usually the cause | Repair or replace |
|---|---|---|
| Runs constantly, or refills on its own | Worn flapper or a fill valve that will not shut off | Repair. Small parts, and it is wasting a great deal of water |
| Weak or incomplete flush | Mineral scale blocking the rim jets, a bad flapper, or low tank water level | Repair in most cases |
| Water pooling around the base | Failed wax ring, loose closet bolts, or a cracked base | Repair unless the bowl itself is cracked |
| The toilet rocks when you sit | Loose bolts, a deteriorated flange, or an uneven floor | Repair. Ignoring it destroys the wax seal underneath |
| Clogs repeatedly, same toilet | Low-flow first generation model, scale in the trapway, or something lodged | Repair first, then consider replacement if it is an old low-flow unit |
| Bubbles or rises when a sink drains | Not the toilet. That is a vent or main line issue | Camera inspection |
| Leak between tank and bowl | Failed tank-to-bowl gasket or bolts | Repair |
| Cracked tank or bowl | Age, impact, or freeze damage | Replace. Porcelain cracks do not get repaired |
| Sweating tank in summer | Condensation from cold supply water in a humid room | Usually a ventilation matter rather than a fault |
The Parts That Fail, and Why It Matters
A toilet is a handful of inexpensive components sitting inside a porcelain fixture that itself rarely fails. Knowing that changes how you hear a quote.
-
The flapper
The rubber seal at the bottom of the tank. It hardens and warps with age and with hard water, then stops sealing, and the toilet refills every few minutes. The single most common cause of a running toilet and one of the cheapest parts in the house.
-
The fill valve
Refills the tank after a flush and shuts off at the right level. When it fails the toilet either runs continuously, refills forever, or never fills enough to flush properly.
-
The wax ring
Seals the toilet to the drain flange. When it fails you get water at the base and eventually damage to the subfloor. A rocking toilet destroys this seal, which is why the rocking is worth fixing early.
-
The closet flange
The fitting that connects the toilet to the drain. Cast iron flanges in older Metro Detroit homes corrode and break, and a broken flange is why some toilets will not stay tight no matter how hard the bolts are turned.
-
Supply line and shutoff
The flexible line and valve behind the toilet. Old shutoffs seize, which you discover at the worst possible moment. Worth replacing whenever a toilet is being worked on anyway.
-
The trapway
The internal S-bend moulded into the porcelain. Mineral scale narrows it over years, which is why an old toilet in a hard water area starts clogging more often than it used to.
A Running Toilet Is Not a Small Problem
It is quiet, it does not damage anything, and it is very easy to live with for months. It is also one of the largest sources of wasted water in a home, capable of putting hundreds of gallons a day through your meter without anybody noticing.
The simple test: put a few drops of food colouring in the tank and do not flush. Come back in fifteen or twenty minutes. If colour has appeared in the bowl, the flapper is leaking and the toilet is running whether you can hear it or not.
The fix is normally a flapper and sometimes a fill valve. If you have had an unexplained jump in your water bill, this is the first thing to rule out, and it is one of the cheapest repairs we do.
When It Is Not the Toilet at All
The toilet is often where a drain problem becomes visible, rather than where it lives. These signs mean the fixture is fine and the line is not.
- The bowl bubbles or the level rises when a sink or shower drains. Air is being pushed through the trap, which means a restriction or a venting problem downstream.
- Other fixtures are slow at the same time. A toilet that clogs alone is a toilet. A toilet that clogs while the tub is also draining slowly is the main line.
- Water appears at the basement floor drain when the toilet is flushed. That is a main line backup and it is urgent.
- Plunging works, then it clogs again within days. The blockage is reforming further down rather than in the trap.
In each of those cases replacing the toilet changes nothing. A camera inspection finds the actual restriction, and then it is a drain cleaning or a sewer repair rather than a fixture job.
Things That Make a Toilet Problem Worse
- Flushing repeatedly to clear a clog. If the first flush did not go down, the second one overflows onto your floor.
- Chemical drain openers in a toilet. They rarely clear a toilet clog, they sit in the trapway, and they make the fixture hazardous for whoever works on it next. Tell us if any have been used.
- Wipes, even the flushable ones. They pass the toilet, which is all that claim means, then fail to break down in the line. They are the most common thing we pull out of residential main lines.
- Overtightening the closet bolts on a rocking toilet. Porcelain cracks, and a cracked base turns a wax ring repair into a replacement.
- Living with a rocking toilet. Every movement works the wax seal loose, and the water that escapes goes into the subfloor where you cannot see it.
If It Does Need Replacing
-
Rough-in measurement
The distance from the finished wall to the centre of the closet bolts, usually 12 inches but sometimes 10 or 14 in older homes. Get this wrong and the toilet does not fit. We measure before ordering.
-
Height
Standard height and comfort height, the latter sitting closer to chair height. Worth choosing deliberately rather than by accident, particularly if anyone in the house has mobility considerations.
-
Flush performance
Modern low-flow toilets flush considerably better than the first generation of them, which is why an older low-flow unit that clogs constantly is often worth replacing rather than repairing again.
-
What we check underneath
Flange condition, floor condition, and the shutoff valve. Fitting a new toilet onto a broken flange or a rotten subfloor is how a replacement fails within a year.
Pricing and permits
A straight toilet replacement is a fixture swap and is not normally permitted work, unlike a water heater or a sewer repair. That keeps it simpler than most of what we do.
We charge a service call fee to come out, diagnose the problem, and quote it, and that fee is applied to the work if you go ahead. You approve the price before anything starts. We do not offer free estimates, because a free estimate is a guess rather than a diagnosis.

Toilet Repair FAQ
Why does my toilet keep running?
Nearly always the flapper, the rubber seal at the bottom of the tank. It hardens and warps with age and hard water, stops sealing, and lets water trickle into the bowl so the tank refills every few minutes. The fill valve is the next most common cause. Both are inexpensive parts, and a running toilet can waste hundreds of gallons a day, so it is worth fixing quickly.
Is it cheaper to repair or replace a toilet?
Repair, in most cases. Flappers, fill valves, wax rings, and tank gaskets are inexpensive and fix the large majority of complaints. Replacement makes sense when the porcelain is cracked, when the flange or floor underneath needs work anyway, or when an old first-generation low-flow toilet clogs so persistently that repeated repairs stop being good value.
Why is there water around the base of my toilet?
Usually a failed wax ring, loose closet bolts, or a deteriorated flange. Occasionally it is condensation rather than a leak. It is worth addressing promptly either way, because water at the base soaks into the subfloor where you cannot see the damage accumulating.
My toilet rocks. Does that matter?
Yes. Every movement works the wax seal loose, and once that fails water escapes under the toilet into the floor. Do not simply tighten the bolts harder either, because overtightening cracks porcelain. The cause is usually loose bolts, a corroded flange, or an uneven floor, and each needs a different fix.
My toilet bubbles when the sink drains. What is that?
That is not a toilet fault. Air being pushed back through the trap means a restriction or a venting problem in the line the fixtures share. If other drains are slow at the same time, treat it as a main line issue. See camera inspection and sewer repair.
Why does the same toilet clog over and over?
Three common reasons. Mineral scale has narrowed the internal trapway over years, which happens with our water. It is an early low-flow model that never flushed well. Or the blockage is downstream and reforming, in which case it is not the toilet at all. If plunging works and it clogs again within days, look at the line rather than the fixture.
Do I need a permit to replace a toilet in Michigan?
Normally no. A like-for-like fixture replacement is not usually permitted work, unlike a water heater replacement or a sewer repair, which typically are. If the work involves moving the drain or altering the rough plumbing, that changes, and we will tell you if your job crosses that line.
Are flushable wipes really a problem?
Yes. They pass the toilet, which is all the label claims, then fail to break down in the line the way toilet paper does. They catch on anything irregular in the pipe and build from there, and they are the most common item we pull out of residential main lines. Paper towels, dental floss, and cat litter behave the same way.
Do you replace toilets in commercial buildings?
Yes, including flushometer and commercial-grade fixtures in offices, retail, restaurants, and multi-tenant properties. See commercial plumbing.
