Replacing the seal in a Fluidmaster toilet fill valve is a simple and cost-effective fix if your toilet is running or filling slowly. Here's a step-by-step guide:

🛠️ Tools & Materials Needed:

• Replacement Fluidmaster seal (usually part #242)

• Towel or small container (to catch water)

• Adjustable wrench (optional)

---

🔧 Step-by-Step Instructions:

1. Turn Off the Water Supply

• Locate the shut-off valve (usually behind or below the toilet).

• Turn it clockwise to stop water flow.

2. Flush the Toilet

• Flush to empty the tank.

• Hold the handle down to get as much water out as possible.

• Use a towel or sponge to soak up any remaining water at the bottom of the tank if needed.

3. Remove the Fill Valve Cap

• The Fluidmaster fill valve cap is usually secured with a twist-lock mechanism.

• Hold the shaft of the fill valve with one hand.

• With the other hand, twist the top cap counterclockwise about 1/8 of a turn and lift it off.

• Some models require gently squeezing side tabs before twisting.

4. Replace the Seal

• Inside the cap, you’ll see a small rubber seal (usually red or black).

• Remove the old seal (you can use a small flathead screwdriver or your fingers).

• Insert the new seal in the same position, making sure it sits flat and centered.

5. Reinstall the Cap

• Line up the cap on top of the valve body.

• Twist it clockwise to lock it back into place.

6. Turn the Water Back On

• Slowly open the shut-off valve.

• Let the tank fill and check for leaks.

• Flush the toilet to ensure proper operation.

✅ Tips:

• The Fluidmaster 400A is the most common model. Make sure you’re using the right seal for your valve.

• If replacing the seal doesn’t solve the issue, the whole fill valve may need to be replaced (also inexpensive and easy).
