Why You Should Fix a Running Toilet in Kent

Before you grab your toolbox, it’s useful to understand why your toilet might be running:

• Faulty Flapper Valve: The flapper controls the release of water from the tank to the bowl. If it’s worn out or misaligned, water will continue leaking into the bowl.
• Float Positioning: If the float is too high, water will keep entering the tank, overflowing into the overflow tube.
• Fill Valve Problems: The fill valve controls the water entering the tank. A broken or dirty valve can cause constant running.
• Chain Issues: If the chain connecting the flush lever to the flapper is too tight or too loose, it can prevent the flapper from sealing properly.

If you’re facing bigger problems, like leaks, you can always explore our Leak Detection services available across Swanley, Dartford, and nearby areas.

Step 1: Turn Off the Water Supply

Locate the shut-off valve behind the toilet near the floor and turn it clockwise to stop water flowing into the tank. Flush the toilet to empty most of the water, making it easier to work.

Step 2: Check and Replace the Flapper

The flapper is often the main cause of a running toilet. Remove the tank lid and inspect the rubber flapper at the bottom. If it’s warped, cracked, or doesn’t sit flat, replace it. Flappers are inexpensive and available at most DIY stores.

If you prefer a professional repair, our Kent plumbers can handle it quickly and affordably.

Step 3: Adjust the Float

If the water level is too high, it spills into the overflow tube. Adjusting the float fixes this issue:

• Ball Float: Gently bend the arm downward so the ball sits lower when the tank fills.
• Cylinder Float: Turn the adjustment screw counterclockwise to lower the float.

Aim for a water level about one inch below the overflow tube.

Step 4: Inspect and Replace the Fill Valve

If adjusting the float doesn’t help, your fill valve may be faulty. Turn off the water supply and flush again. Disconnect the water line, remove the old fill valve, and install a new one following the instructions provided. Reconnect, turn on the water, and test the toilet. This simple step can help fix a running toilet in Kent homes without major cost.

Step 5: Shorten or Replace the Chain

A chain that’s too tight or too slack can interfere with the flapper. Adjust it so there’s about half an inch of slack — just enough for smooth movement without snagging.

Prevent Future Toilet Issues

Maintenance is key. Here’s how to prevent running toilet problems:

• Inspect the flapper every six months.
• Clean mineral deposits using vinegar or mild descaler.
• Ensure the float and fill valve move freely.
• Call DAKS Plumbing for an annual inspection to avoid emergencies.
