Recently I succumbed to temptation—or stupidity. More accurately, a healthy combination of both. I dumped clumping cat litter into our basement toilet.
I'd temporarily moved our cat's litter box from the basement storage room into the basement bathroom. One evening, while scooping it out, I decided that instead of using one of our increasingly scarce plastic grocery bags, I'd toss a single clump into the toilet and flush it. I swear the clump was no bigger than half the palm of my hand.
I knew instantly I'd made a mistake.
The toilet didn't flush. Instead, the bowl filled to the brim.
"Well... that's not good," I muttered as I reached for the plunger.
Half a dozen plunges later, the water had gone down only slightly. More plunging, more splashing, and eventually it receded to about its normal resting level. Thinking the flush itself might push the clog through, I tried again.
Nope.
The bowl filled again, this time stopping just shy of overflowing.
At that point my wife asked, "Did you throw cat litter in the toilet?"
Busted.
I turned to YouTube and quickly discovered I wasn't alone. Apparently plenty of people have made the exact same mistake. The most common advice was to pour hot—but not boiling—water into the bowl to soften the clumped litter. Boiling water could crack the toilet. Best not to make a bad situation even worse.
After six or seven buckets of hot water, the toilet finally flushed.
Sort of.
The bowl emptied, but it ended with a suspicious glug... glug... glug instead of its usual confident whoosh. I optimistically declared victory.
"I think we're good."
The next morning proved otherwise.
The first flush backed the toilet up almost to the rim again. By the time I left for work, the water had slowly drained away, so I convinced myself the clog had finally worked loose. I poured in another bucket of hot water and flushed.
Same result.
I closed the lid and decided Future Me could deal with it.
Out of sight, out of mind.
Two or three days later I tried again.
Still clogged.
Twenty... maybe thirty plunges accomplished absolutely nothing. More buckets of hot water? Also, nothing.
Honestly, I shouldn't have been surprised. This clumping litter bonds to the bottom of the litter box like concrete. Why did I think it would magically dissolve inside a toilet?
I figured I had three options.
First, call a plumber.
No thanks. That's expensive, and I was convinced this was something I could fix myself.
Second, buy a toilet auger.
Also no. They're not cheap, and this was hopefully a one-time disaster. Besides, returning a plumbing tool after you've used it feels... wrong.
That left option three: pull the toilet.
The hardest part wasn't removing it—it was getting all the water out first. Two shop-vac loads later I noticed the tank kept slowly refilling because the shutoff valve wasn't shutting off completely.
Lovely.
I shut off the water to the house and opened the sink faucets to drain the plumbing. Unfortunately, the toilet's supply line sat lower than the sinks, so about a gallon of perfectly clean water emptied itself onto the linoleum before everything finally stopped.
After repairing the leaky valve cartridge, I turned the water back on—with the toilet valve still closed—vacuumed out the remaining water, removed the tank, and finally lifted the bowl.
I tipped it over expecting to find a giant wad of cat litter.
Nothing.
Great.
Next, I poured a bucket of hot water into the floor drain. It disappeared without backing up.
Whew.
That meant the house drain was fine. The clog had to be inside the toilet itself.
I carried the bowl outside and set it down on a, no pun intended, wooden stool with the drain hole exposed.
I filled the bowl with water from the garden hose, then dumped a bucket of water into it. Instead of flowing freely, it backed up exactly as it had for the past week.
Aha.
The clog was definitely inside the toilet.
I shoved the garden hose into the bowl and turned it on full blast.
Nothing.
I flipped the bowl over and blasted water from the other direction.
Still nothing, except a lot of water spraying back at me.
Running out of ideas, I straightened a wire coat hanger and fed it into the outlet on the bottom. About six inches in, I hit something solid.
Progress.
After ten or so determined jabs, I pulled the hanger back out.
It was coated with cat litter that had transformed into something resembling soft concrete.
Seriously, what is this stuff made of?
More poking.
More blasting with the hose.
Then suddenly...
Splash.
A satisfying rush of water shot through the toilet, followed by a surprisingly large chunk of gray litter that was easily twice the size of what I'd originally flushed. Apparently that tiny clump had grown into its own geological formation.
I stood there soaked in sweat, hose and toilet water, staring at the innocent-looking pile of gray sludge while silently questioning my life choices.
After thoroughly cleaning and sanitizing the bowl, I carried it back inside, reinstalled everything, and gave it the moment of truth.
It flushed perfectly.
The same powerful flush that had convinced me, in a moment of spectacular overconfidence, that it could handle anything.
It couldn't.
Lesson learned.
Never flush clumping cat litter.
Not even once.
