We all know that sound, right? That gentle, persistent trickle that tells you your toilet is wasting water – and your money. For weeks, my upstairs bathroom toilet had a mind of its own. It wasn’t a dramatic flood, just a quiet, annoying leak that kept the tank from staying completely full. I’m Elias, and like many of you, I like to tackle home issues myself when I can. This leaky toilet was a real test of patience.
My first suspect was the flapper. It’s the rubbery seal at the bottom of the tank that lifts when you flush. Over time, these can get old, brittle, or just not seat properly, allowing water to seep into the bowl. I headed to the hardware store, picked up a new, universal flapper, and swapped it out. Easy enough, I thought.
For a day, it seemed fixed. Then, the tell-tale trickle returned. Back to square one.
Next on my list was the fill valve, also known as the ballcock. This is the mechanism that refills the tank after a flush and shuts off the water when the correct level is reached. If it’s not shutting off completely, water can overflow into the overflow tube, which leads straight to the bowl, causing that same incessant drip. Replacing this is a bit more involved, requiring turning off the water supply and a bit of wrenching. I replaced the entire assembly, carefully following the instructions.
Again, a day of blessed silence. And then, the trickle. I was starting to get a little frustrated. This toilet seemed determined to keep me on my toes.
I decided to do a more thorough inspection of the tank’s internals. I watched closely as the water level rose after a flush. Everything seemed to be shutting off correctly. The flapper was firmly seated. The fill valve was indeed stopping the water flow at the right height.
So, what was left? There’s a small tube that comes from the fill valve, usually attached to the overflow tube, called the refill tube. Its job is to send a small amount of water down the overflow tube to refill the bowl after each flush. Most of the time, this is a very short burst. But what if it was running for too long?
I noticed my refill tube was positioned a little too low, almost submerged into the overflow tube. It wasn’t just a short burst; it was a continuous trickle, enough to keep the water level just below the point where the fill valve would shut off completely. It was a subtle leak, one that was easily masked by the normal operation of the fill valve.
My fix? I adjusted the clip on the refill tube, raising it so that it was just above the waterline in the tank, but still above the overflow opening. This way, it only sends water down the overflow tube for a brief moment after the flush, just enough to keep the bowl water level correct.
After the adjustment, I waited. And waited. The silence was golden. That persistent trickle was gone, replaced by the satisfying quiet of a properly functioning toilet. It turns out, sometimes the simplest solutions are hiding in plain sight, or in this case, right at the top of the tank.
