A toilet that runs, rocks, clogs often or seeps at the base is one of the most common calls in an Auburn Hills home, and most of it is fixable without a new fixture. The exceptions are a cracked bowl or tank and a toilet you simply want replaced, which is a clean, same-visit job when the flange and floor are sound.
Here is what each toilet problem means, and what a proper repair or new install involves.
The toilet that runs and never quite stops
A toilet that keeps running, or cycles on by itself every so often, is wasting water and almost always a worn flapper or fill valve inside the tank. The flapper is the rubber seal that lifts to flush and drops to seal; when it hardens or warps, water leaks past it into the bowl until the fill valve kicks on to top the tank back up. A fill valve that will not shut off cleanly does the same. Both are straightforward rebuilds, and fixing them stops the quiet creep on your water bill that a running toilet causes.
A rocking toilet and a seep at the base
A toilet should sit solid. One that rocks is working its seal loose, and water weeping onto the floor around the base, or a stain on a ceiling below, points to the wax ring that seals the toilet to the closet flange having failed. Rocking and a failed seal go together: the movement breaks the wax, and a broken seal lets sewer gas and water out. The fix is to pull the toilet, replace the wax ring, check the flange for cracks or a low height, shim the toilet level and reset it. Ignored, a seeping base rots the subfloor under it.
A toilet that clogs more than it should
An occasional clog is normal; a toilet that clogs weekly is telling you something. It can be an early low-flow toilet from the 1990s that never had the flush volume to clear the line, a partial blockage downstream in the branch or main drain, or a vent problem that keeps the bowl from flushing fully. We look at whether it is the fixture or the line before recommending a new toilet, because a modern toilet flushes far better than an early low-flow one, but swapping it does nothing if the real problem is roots or a clog further down.
Installing a new toilet the right way
A new toilet is a simple install when the basics are right. We confirm the rough-in, the distance from the wall to the flange bolts, so the toilet fits, check that the flange sits at the correct height above the finished floor, especially after new tile has raised it, and set the bowl on a fresh wax ring with the supply and shutoff renewed if they are corroded. Many owners move to a comfort-height, better-flushing model at the same time. On a finished-basement bath fed by an ejector pump, we confirm the toilet suits that system.
Condos, upper floors and the water below
Where the toilet sits changes what a failure costs. In a condo or a two-story Auburn Hills home, a seeping toilet on an upper floor shows up as a stain on the ceiling of the room below, sometimes a neighbor’s unit in a stacked building. That is why a rocking toilet is worth resetting before the seal fails rather than after, and why we check the floor under an upper-floor toilet for soft spots that say the leak has been going a while. Catching it early keeps one wax ring from becoming a ceiling repair.

Older homes have original flanges that sit low after added flooring, so a reset includes correcting the height.

Multi-bath homes mean more toilets and more running flappers and fill valves to rebuild.
- Plumber in Birmingham
Remodeled baths raised floor height with new tile, so new toilets need the flange height confirmed on install.
- Plumber in Royal Oak
Older homes with added upstairs baths put toilets over living space, where a seeping base is caught early.
- Plumber in Lake Orion
Finished lower-level baths on ejector systems need toilets matched to how that system clears the bowl.

County-wide, running flappers, failed wax rings and dated low-flow toilets are the everyday toilet calls.
Toilet repair and installation questions from Auburn Hills customers
Why does my toilet keep running?
Almost always a worn flapper or fill valve in the tank. The flapper is the rubber seal that hardens and lets water leak into the bowl, so the fill valve keeps topping the tank up. A fill valve that will not shut off cleanly does the same. Both are simple rebuilds, and fixing them stops the steady waste a running toilet adds to your bill.
My toilet rocks and leaks at the base. What is wrong?
The wax ring sealing the toilet to the flange has failed, and the rocking is what broke it. Water weeping at the base, or a stain on the ceiling below, is the sign. The fix is to pull the toilet, replace the wax ring, check the flange, shim the toilet level and reset it. Left alone, it rots the subfloor underneath.
Should I repair or replace a toilet that clogs often?
It depends on why. An early 1990s low-flow toilet may never have had the flush to clear the line, and a modern toilet flushes far better. But frequent clogs can also be a blockage or vent problem downstream, which a new toilet will not fix. We check whether it is the fixture or the line before recommending a replacement.
Can you install a toilet I bought myself?
Yes. We confirm the rough-in fits, check the flange height, especially if new flooring raised it, set the bowl on a fresh wax ring, and renew the supply line and shutoff if they are corroded. If the old toilet was on a finished-basement ejector system, we make sure the new one suits it. A correct set is what keeps it from rocking or seeping later.
