If you’re dealing with a running toilet in Sammamish, you’re not alone. It may seem like a small issue, but it often signals a bigger problem. While most people assume the flapper is the reason, that’s not always the case. There are several other possible causes that need to be checked before the problem gets worse or costs you more money.

Fill Valves Wear Out Over Time

One often-overlooked part is the fill valve. If it’s worn or misaligned, it won’t shut off properly. Water keeps flowing, even when the tank appears full. This leads to constant refilling and water waste. We replace fill valves regularly and can spot when they’re causing the issue within minutes.

Cracks in the Overflow Tube

A cracked or damaged overflow tube can also let water leak from the tank into the bowl. The problem is subtle and often missed. Most homeowners don’t know what to look for. Our technicians inspect every part of the toilet tank to make sure nothing is overlooked.

Corroded Internal Parts

Many toilets have internal components made of metal or plastic that can corrode or break down over time. Corroded bolts, rusted washers, or a faulty flush lever can all lead to slow leaks. These problems might not be obvious until we take a closer look inside the tank.

Improper Installation From the Start

In some cases, the issue began when the toilet was first installed. A poorly seated fill valve or a misaligned float can cause the toilet to run non-stop. We often fix problems that result from rushed or unskilled installations.

Professional Diagnosis Matters

Fixing a running toilet is not just about changing a flapper. Our team uses a step-by-step process to figure out exactly what’s wrong. We don’t guess. We diagnose. Our goal is to make sure your toilet runs efficiently and doesn’t waste water or increase your bills.
