Is your toilet running on and off throughout the day, driving up your water bill and keeping you awake at night? A toilet that runs intermittently is one of the most common plumbing problems homeowners face in West Richland, Pasco, and throughout Washington. The good news? Many intermittent running toilet issues can be fixed with simple repairs that take just minutes to complete.

At DDB Plumbing, we’ve helped thousands of homeowners resolve this frustrating problem. While some toilet issues require professional attention, we’re sharing three easy fixes you can try before calling for help.

Understanding Why Your Toilet Runs Intermittently

Before diving into solutions, it’s important to understand what causes a toilet to run sporadically. Your toilet contains a fill valve, flapper, and flush valve that work together to refill the tank after each flush. When these components wear out or become misaligned, water slowly leaks from the tank into the bowl, triggering the fill valve to turn on intermittently to maintain water levels.

This phantom flushing not only wastes water—sometimes up to 200 gallons per day—but also indicates that your toilet components need attention. Homeowners in Kennewick and Richland often notice this problem worsening during winter months when mineral deposits accumulate faster in the tank.

Solution #1: Replace Your Toilet Flapper

The flapper is the rubber seal at the bottom of your toilet tank that lifts when you flush. Over time, this rubber deteriorates, warps, or accumulates mineral buildup, preventing a proper seal. This is the most common cause of intermittent running.

How to fix it:

• Turn off the water supply valve behind your toilet
• Flush to empty the tank
• Unhook the old flapper from the flush valve
• Take it to a hardware store to find an exact replacement
• Install the new flapper and turn the water back on

Flappers cost between $5-10 and take about 10 minutes to replace. If you’re uncomfortable performing this repair, DDB Plumbing offers quick, affordable service throughout the Tri-Cities area.

Solution #2: Adjust or Replace the Fill Valve

The fill valve controls water flow into your tank. If it’s set too high, water flows into the overflow tube, causing the toilet to run. If the valve itself is faulty, it may not shut off completely.

How to fix it:

• Check your water level—it should be about one inch below the overflow tube
• Adjust the float by turning the adjustment screw or pinching the clip (depending on your valve type)
• If adjusting doesn’t work, the fill valve may need replacement
• New fill valves cost $10-20 and install in about 20 minutes

Solution #3: Check the Flush Valve and Overflow Tube

Sometimes the problem isn’t the flapper or fill valve—it’s the flush valve assembly itself. Cracks in the overflow tube or a corroded flush valve can cause persistent running issues.

How to fix it:

• Inspect the overflow tube for cracks or damage
• Check the flush valve seat for mineral deposits or damage
• Clean mineral buildup with white vinegar
• If cracked or severely corroded, replace the entire flush valve assembly

This repair is more involved and may require a professional plumber’s expertise.

When to Call a Professional Plumber

While these DIY solutions work for many intermittent running toilet problems, some situations require professional help. Contact a licensed plumber if:

• Your toilet continues running after trying these fixes
• You notice water leaking around the base of the toilet
• The tank or bowl has visible cracks
• You’re uncomfortable performing repairs yourself
