The most common toilet repair parts needed include: 1. **Flapper**: This rubber component seals the flush valve and controls water release from the tank to the bowl. Over time, it can warp or degrade, causing leaks or incomplete flushing. 2. **Fill Valve**: This part controls the water level in the tank. A malfunctioning fill valve can lead to continuous running water or insufficient water in the tank. 3. **Flush Valve**: This assembly includes the overflow tube and the seat for the flapper. It can wear out, leading to leaks or inefficient flushing. 4. **Toilet Handle and Lift Chain**: The handle initiates the flush, and the chain connects it to the flapper. If either breaks or becomes disconnected, the toilet won't flush properly. 5. **Wax Ring**: This seal between the toilet base and the floor flange prevents leaks. It can degrade over time, leading to water leakage at the base of the toilet. 6. **Tank Bolts and Gaskets**: These secure the tank to the bowl and ensure a watertight seal. Corrosion or wear can cause leaks between the tank and bowl. 7. **Ballcock**: An older type of fill valve that can wear out, leading to water flow issues. 8. **Float Ball and Arm**: Part of the fill valve system, they regulate the water level in the tank. If they malfunction, it can cause overfilling or insufficient filling. 9. **Flush Lever**: The external handle that can break or become loose, preventing proper flushing. 10. **Supply Line**: This connects the water supply to the toilet. Leaks or blockages can occur if it becomes damaged or worn. These parts are essential for maintaining a functional toilet and addressing common issues like leaks, running water, and flushing problems.

To fix a running toilet, follow these steps: 1. **Turn Off Water Supply**: Locate the shut-off valve behind the toilet and turn it clockwise to stop water flow. 2. **Remove Tank Lid**: Carefully lift the lid off the tank and set it aside. 3. **Check the Flapper**: Inspect the rubber flapper at the bottom of the tank. If it's worn or not sealing properly, it may need replacement. Turn off the water, drain the tank, and replace the flapper if necessary. 4. **Adjust the Chain**: Ensure the chain connecting the flapper to the flush handle is not too tight or too loose. It should have a little slack but not so much that it gets caught under the flapper. 5. **Inspect the Fill Valve**: Check the fill valve for proper operation. If water is continuously flowing into the overflow tube, adjust the float. For a float ball, bend the arm gently to lower the water level. For a float cup, use the adjustment screw or clip to set the correct water level. 6. **Examine the Overflow Tube**: Ensure the water level is about an inch below the top of the overflow tube. Adjust the fill valve as needed to maintain this level. 7. **Test the Flush**: Turn the water supply back on and let the tank fill. Flush the toilet to ensure the problem is resolved. Check for leaks or continuous running. 8. **Replace Parts if Needed**: If adjustments don't work, consider replacing the fill valve or other faulty components. 9. **Reattach Tank Lid**: Once the toilet is functioning correctly, place the lid back on the tank. These steps should help resolve most running toilet issues. If problems persist, consult a plumber.

To fix a leaking toilet tank, first turn off the water supply to the toilet by closing the shut-off valve located behind or near the toilet. Flush the toilet to empty the tank and use a sponge or towel to remove any remaining water. Identify the source of the leak, which could be from the fill valve, flush valve, or tank bolts. If the fill valve is leaking, replace the washer or the entire valve. To do this, disconnect the water supply line, remove the old fill valve, and install a new one according to the manufacturer's instructions. Adjust the float to ensure the correct water level. For a leaking flush valve, remove the tank lid and inspect the flapper. If it's worn or damaged, replace it with a new one. Turn off the water supply, remove the old flapper, and attach the new one to the flush valve. Ensure it seals properly to prevent leaks. If the leak is from the tank bolts, tighten them with a wrench. If tightening doesn't stop the leak, replace the rubber washers and bolts. Drain the tank, remove the old bolts, and install new ones with rubber washers on both sides of the tank to ensure a watertight seal. After repairs, turn the water supply back on and let the tank fill. Check for leaks by observing the tank and floor around the toilet. If leaks persist, consider consulting a professional plumber for further assistance.
