If your toilet still runs after replacing parts, the likely culprits are issues with the flush valve seat (mineral buildup, damage), a misadjusted float/fill valve, or the flapper chain being the wrong length/tangled, preventing a perfect seal or proper shut-off, even with new components. You may need to clean the valve seat thoroughly or adjust the water level in the tank, ensuring the float shuts off the fill valve before water reaches the overflow tube.
If you've replaced the flapper and adjusted the float ball, but the toilet continues to run, the most likely cause is a leaking flush valve. Usually, such a leak is around the mouth of the flush valve where the flapper is supposed to make a good seal.
A running toilet with an empty tank after shutting off the valve indicates a possible fill valve or flapper issue. Check the fill valve for blockage or failure preventing water refill. Inspect the flapper for leaks causing water to drain into the bowl. Replace faulty parts as needed.
Bottom Line
A toilet flapper leaking after replacement is caused by something small like a rough valve seat, mineral buildup, misalignment, a too-tight chain, or an issue with the refill tube. Start with the easy fixes first. Clean, adjust, and realign before spending money on new parts.
If water continues to flow out of the cistern into the bowl odds are the flushing valve seal needs to be replaced. But if the leak stops it means that the water is going out through the overflow valve and inlet valve needs to be repaired or replaced.

A: Ignoring water hammer can lead to gradual damage to your plumbing system, including loosening or dislodging of pipe fittings and joints. Over time, this can result in leaks, water damage, and potentially costly repairs. Addressing water hammer promptly can help prevent these issues.
The aluminum foil ball trick works primarily through water displacement. When you place objects in your toilet tank, they take up space that would normally be filled with water, reducing the amount of water used with each flush. Think of it like dropping rocks into a glass of water.
You should never flush wet wipes (even "flushable" ones) and sanitary products (like tampons/pads) because they don't break down, causing serious blockages in pipes and sewage systems. Other items to avoid include paper towels, tissues, cotton buds, dental floss, hair, and cooking oils/fats, as they all contribute to clogs and environmental issues.
Inspecting your toilet tank components
Fixing a running toilet can be a feasible DIY project, but in most instances, it's wiser to enlist the help of a professional plumber.
The Gate Valve Is Stuck
A valve can also become stuck in the open or closed position, often from lack of use. Turn your valves on and off periodically to keep them moving smoothly. If the valve seizes, shut off the water supply, inspect the area for corrosion or leaks, and try loosening it with a wrench and WD-40.
Gravity and the flow of water pushes waste down the drain. As the tank empties, the flapper lowers back into place, sealing the flush valve to stop water flow. The fill valve then activates, refilling both the tank and the bowl through a small refill tube.
This can be fixed by draining your plumbing system, which requires turning off the main water valve and opening the highest faucet in your home. Then drain water from the lowest faucet. The chamber should fill up with air once the water is drained and resolve your water hammer problem.
How To Stop Water Hammer
A common cause of water hammer can be fast-acting valves on appliances such as washing machines or dishwashers. These valves suddenly stop the water that is moving along the pipes. A shockwave results and this causes the pipes to shudder, causing the banging. The banging gets worse as the valves are worn.
No matter when you hear it, a hissing toilet is not something to ignore. The hissing typically indicates that water is continuously running somewhere it shouldn't be, which can lead to a host of problems, including shockingly high water bills and potential water damage.
Not literally, of course – but your water bill will skyrocket if your toilet is constantly running. More often than not, continuously running toilets are extremely easy and inexpensive to fix – you might just need to replace the flapper. A constantly running toilet also presents an increased risk of flooding.
Can I replace toilet bolts without removing the entire toilet? Yes, it's possible to replace certain toilet bolts, such as those securing the tank to the bowl, without removing the entire toilet. However, replacing the bolts that anchor the toilet to the floor typically requires removing the toilet.
Use toilet shims to support the rear of the toilet higher in the air. Also shim the bowl alongside the bolts to avoid breaking the bow. Without removing your chest from the front of the bowl, install the nuts on the bolts.
