Let’s break it down.

Common Reasons Your Toilet Is Constantly Running

✅ Faulty Flapper ValveThe flapper is the rubber seal at the bottom of your toilet tank. Over time, it can warp, crack, or fail to seal properly — allowing water to leak into the bowl nonstop.

✅ Worn-Out Fill ValveThe fill valve controls the water flow that refills the tank after a flush. If it’s damaged or misadjusted, it can keep refilling endlessly.

✅ Float ProblemsThe float tells the fill valve when to stop refilling the tank. If the float is set too high or gets stuck, water keeps flowing.

✅ Leaky Flush Valve or Tank BoltsWater can escape through worn gaskets or loose bolts at the bottom of the tank, triggering constant refilling.

How Much Water Is a Running Toilet Wasting?

A single running toilet can waste up to 200 gallons of water per day — that’s over 6,000 gallons a month! Not only does this hurt the environment, but it can also add $50–100+ to your monthly water bill.

How to Fix a Constantly Running Toilet

✅ Check the FlapperOpen the tank lid, push the flapper down with a stick or handle, and see if the water stops. If it does, you may need a flapper replacement.

✅ Adjust the FloatMake sure the float isn’t set too high. Adjust the float arm or cup to stop the water at the correct fill line.

✅ Inspect the Fill ValveLook for wear, corrosion, or debris. You may need to clean or replace the fill valve mechanism.

✅ Replace Worn PartsIf you’re handy, you can buy a universal toilet repair kit — but be careful not to overtighten or break fragile parts.
