If your toilet isn’t flushing properly, you may need to replace some of the parts in the tank. This is a relatively easy DIY project that can be completed in about an hour. In this article, we will provide step-by-step instructions on how to replace the most common toilet tank parts, including the flapper valve, fill valve, and handle.
Before you begin, you will need to gather a few tools and materials. These include a wrench, a screwdriver, a pair of pliers, and a new flapper valve, fill valve, and handle. You can find these parts at most hardware stores.
Once you have gathered your tools and materials, you can begin the repair. The first step is to turn off the water supply to the toilet. You can do this by turning the valve that is located behind the toilet. Once the water is turned off, you can flush the toilet to empty the tank. Next, remove the lid from the tank and locate the flapper valve. The flapper valve is a rubber seal that covers the hole at the bottom of the tank. To remove the flapper valve, simply lift it up and off of the flush valve.
Identifying the Problem
Identifying the faulty toilet tank part is crucial before attempting replacement. Here are common symptoms and potential culprits:
Leaking Toilet Tank
| Symptom | Potential Culprit |
|---|---|
| Water leaking from the base of the tank | Leaking tank-to-bowl gasket, worn flapper valve, or damaged flush valve |
| Water overflowing from the tank into the bowl | Faulty fill valve, malfunctioning water-saving device, or cracked flush valve |
| Water dripping from the refill tube | Misaligned refill tube, worn-out rubber washer, or damaged fill valve |
Running Toilet Tank
| Symptom | Potential Culprit |
|---|---|
| Continuous water flow into the bowl | Faulty fill valve, worn-out flapper valve, or damaged flush valve |
Slow Flushing Toilet Tank
| Symptom | Potential Culprit |
|---|---|
| Inadequate water flow during flushing | Clogged refill tube, blocked flush valve, or worn-out flapper valve |
Draining the Tank
Before you can replace any toilet tank parts, you’ll need to drain the tank. To do this, follow these steps:
- Turn off the water supply to the toilet. The water supply valve is usually located behind the toilet, near the floor. Turn the valve clockwise to turn off the water.
- Flush the toilet to empty the tank.
- Use a sponge or towel to absorb any remaining water in the tank.
- Disconnect the water supply line from the fill valve. The fill valve is the tall, cylindrical valve that is located at the back of the tank. To disconnect the water supply line, use a wrench to loosen the nut that is holding the line in place. Pull the water supply line off the fill valve.
Removing the Fill Valve
Once the water supply line is disconnected, you can remove the fill valve. To do this, follow these steps:
- Use a wrench to loosen the nuts that are holding the fill valve in place. There are usually two nuts, one on each side of the valve.
- Pull the fill valve out of the tank. Be careful not to damage the fill valve or the tank.
Replacing the Fill Valve
To replace the fill valve, follow these steps:
- Insert the new fill valve into the tank. Make sure that the gasket on the bottom of the fill valve is seated properly.
- Tighten the nuts that are holding the fill valve in place. Tighten the nuts until they are snug, but do not overtighten them.
- Reconnect the water supply line to the fill valve. Use a wrench to tighten the nut that is holding the line in place.
- Turn on the water supply to the toilet.
- Check for leaks. If there are any leaks, tighten the nuts on the fill valve until the leaks stop.
| Tool | Purpose |
|---|---|
| Wrench | To loosen and tighten nuts |
| Sponge or towel | To absorb remaining water in the tank |
Replacing the Fill Valve
The fill valve is responsible for filling the toilet tank with water when the level drops below a certain point. If the fill valve is not working properly, the toilet may not fill properly or may even overflow. To replace the fill valve, you’ll need:
- New fill valve
- Adjustable wrench
- Screwdriver
- Pliers
Once you have gathered your materials, follow these steps:
- Turn off the water supply to the toilet.
- Flush the toilet to drain the tank.
- Disconnect the water supply line from the fill valve.
- Use the adjustable wrench to loosen the locknut that holds the fill valve in place.
- Remove the fill valve from the tank.
- Install the new fill valve by reversing the steps above.
- Adjust the Fill Valve:
- Reset the fill valve height: The fill valve should be adjusted so that the water level in the tank is about 1 inch below the top of the overflow tube. To adjust the height, turn the screw on top of the fill valve clockwise to raise it or counterclockwise to lower it.
- Adjust the water flow rate: The fill valve should be adjusted so that the tank fills in about 10 seconds. To adjust the flow rate, turn the screw on the side of the fill valve clockwise to increase the flow rate or counterclockwise to decrease the flow rate.
Replacing the Flush Valve
The flush valve is a crucial component of any toilet tank, responsible for releasing water into the bowl and initiating the flushing action. Replacing a faulty flush valve is a relatively straightforward task that can be accomplished in a few steps:
- Turn off the water supply to the toilet.
- Flush the toilet to drain the remaining water in the tank.
- Remove the tank lid.
- Locate the flush valve assembly, typically positioned at the bottom of the tank.
- Disconnect the water supply line from the flush valve.
- Unscrew the locknut that secures the flush valve to the tank.
- Carefully lift the flush valve out of the tank.
- Inspect the washer attached to the bottom of the flush valve. If the washer is damaged or worn, it is essential to replace it with a new one. To do so, carefully remove the old washer by prying it off with a flathead screwdriver or a pair of pliers. Ensure that the new washer is correctly aligned and securely attached to the flush valve’s base before proceeding.
- Place the new flush valve into the tank and tighten the locknut.
- Reconnect the water supply line.
- Turn on the water supply and flush the toilet to test the new flush valve.
