Troubleshooting and Repairing Common Toilet Issues with Plumbchoice

Toilets are essential fixtures in every home, yet they're often taken for granted—until something goes wrong. Whether it’s a constantly running toilet, a weak flush, or a mysterious leak, dealing with toilet issues can be frustrating. The good news? Many common toilet problems can be diagnosed and fixed with a bit of know-how and the right tools.

At Plumbchoice, we’re committed to making toilet maintenance and repairs simple and stress-free. In this post, we’ll walk you through some of the most common toilet troubles and how to fix them.

Running Toilet

The Problem: A toilet that runs continuously after flushing isn’t just annoying—it wastes water and drives up your utility bill.

The Fix: This usually indicates a problem with the flapper valve not sealing properly or the float being set too high. Start by opening the tank and inspecting the flapper for wear or buildup. If it's not sealing properly, replace it. Adjust the float so that the water level stops about an inch below the overflow tube.

Pro Tip from Plumbchoice: Use high-quality flappers and replacement parts to extend the lifespan of your repairs.

Weak or Incomplete Flush

The Problem: When your toilet flushes sluggishly or doesn’t clear the bowl entirely, it might be due to clogged rim holes or a partial blockage in the trap or drain.

The Fix: First, check for mineral buildup under the rim holes—use a small mirror and a wire brush or descaling cleaner to clear them. If the problem persists, try plunging the toilet or using a toilet auger to dislodge a hidden clog.

Plumbchoice Suggests: Regular cleaning with non-corrosive solutions can prevent buildup and maintain flush efficiency.

Phantom Flushing

The Problem: You hear your toilet refilling even though it hasn't been flushed. This is often caused by a slow leak from the tank into the bowl.

The Fix: Add a few drops of food coloring to the tank and wait 30 minutes. If the color appears in the bowl, your flapper is likely leaking. Replace it with a new one that fits your toilet model.

Plumbchoice Tip: Always turn off the water supply before starting any repair.

Toilet Leaks

The Problem: Water pooling around the base of the toilet could mean a faulty wax ring seal or a cracked toilet base.

The Fix: Tighten the bolts on the base of the toilet. If leaking continues, the wax ring may need to be replaced. This repair involves removing the toilet, replacing the ring, and reseating the unit.

Important: If you're unsure, it’s best to call a professional to avoid water damage and improper installation.

Toilet Won’t Flush

The Problem: A toilet that won’t flush could stem from a disconnected lift chain, broken handle, or water level that’s too low.

The Fix: Open the tank and reconnect or adjust the chain attached to the flapper. If the handle is broken, it’s usually a simple replacement. Make sure the tank is filling to the correct water level—about an inch below the overflow tube.

Plumbchoice Advice: Always use compatible replacement parts for your toilet model to ensure proper function.
