Don’t Let That Annoying Running Toilet Drain Your Wallet – Here’s How to Fix It Fast!
A running toilet is one of the most frustrating household problems that homeowners face. A running toilet can waste up to 200 gallons a day or 6000 gallons of fresh water a month, which means your water bill could skyrocket if you don’t address the issue quickly. The good news? Most problems that cause a toilet to run and waste water are DIY repairs, and you don’t need to be a plumbing expert to tackle them.
Understanding Why Your Toilet Won’t Stop Running
Before diving into solutions, it’s helpful to understand how your toilet works. Toilets work on gravity. When you push down the lever it lifts up a rubber flapper, allowing water to run out of the tank and into the bowl. When this system gets disrupted, you end up with a toilet that runs continuously.
When water is escaping from the toilet tank somewhere or a component inside the toilet is leaking, the toilet will continue to run. Generally, this is caused by a leaking flapper, a defective fill valve, or an incorrectly sized overflow pipe.
The Most Common Culprits Behind Running Toilets
1. Faulty Flapper Valve
The flapper valve is often the main culprit behind a running toilet. This simple rubber piece sits at the bottom of your tank and creates a seal over the drain hole. When it gets old or doesn’t align properly, water leaks into the bowl between flushes.
Signs your flapper needs attention include a hissing sound or check for water trickling into the bowl. These are clear indicators that the flapper may be the issue.
2. Problematic Fill Valve
The fill valve controls when water stops flowing into your tank. If you hear a constant hissing, the fill valve might be having trouble shutting off the water supply properly. When this component fails, your toilet will continue running even when the tank is full.
3. Incorrect Float Settings
The float plays an equally important role in preventing running toilets. It moves up and down with the water level to control when the tank refills. If your float is damaged or set incorrectly, water keeps flowing into the tank endlessly.
4. Chain Issues
The chain connecting your flush handle to the flapper can cause problems when it’s too long or too short. A chain that’s too short or tangled won’t allow the flapper to close and water will continue to leak into the bowl. This causes the fill valve to cycle on and off to refill the tank. A chain that’s too long, or a flush rod that hits the tank lid, won’t open the flapper wide enough to stay open for the full flush.
DIY Solutions That Actually Work
Step 1: Check and Replace the Flapper
Start by removing your toilet tank lid and examining the flapper. Check the flapper Lift the tank lid and make sure it’s sealing properly. If it’s stiff, cracked, or in rough shape, replace it. It’s an inexpensive fix.
To replace a flapper:
- Turn Off Water Supply: Locate the shut-off valve behind the toilet and turn it off
- Flush the toilet to empty the tank
- Remove the old flapper and take it to your hardware store for an exact match
- Install the new flapper according to package instructions
- Hook the flapper chain onto the flush lever arm so there’s a little slack when the flapper is closed
Step 2: Adjust the Chain Length
To avoid low water in the toilet bowl and other problems, adjust the linkage in the chain to leave only a slight bit of slack when the flapper is closed. Cut off the excess chain at the rod to leave only about an inch extra to reduce the potential for tangles.
Step 3: Fix Float Problems
For older toilets with float balls, you’ll have to bend the brass rod that connects to the float ball to make adjustments. But with newer toilets, you usually turn a screw or slide a clip along a rod. Flush the toilet after each adjustment. Keep adjusting the float until the water shuts off at the proper level.
The proper water level should be 1/2- to one-inch below the top of the overflow pipe.
Step 4: Replace the Fill Valve
If adjusting the float doesn’t solve the problem, you may need to replace the fill valve. Occasionally, if the fill valve simply won’t shut off, which means that it’s defective, and you’ll have to replace it. Turn the water supply off at the shutoff under the tank. Disconnect the water supply line, unscrew the fill valve locknut and lift out the old fill valve. Insert the new fill valve into the tank according to the instruction sheet and tighten the locknut a half turn past hand tight.
