How to Stop a Constantly Running Toilet by Adjusting the Fill Valve Float · Step 1 of 5
In this video
Carefully lift the toilet tank and place it onto the back of the toilet bowl. Ensure the large rubber gasket is properly seated between the tank and bowl. Align the holes and insert the tank bolts from inside the tank. Secure them from underneath with washers and nuts. Use a screwdriver to hold the bolt head still while you tighten the nut with a wrench. Tighten both sides evenly and gradually to avoid cracking the porcelain.
Goal: Assemble Toilet
- Tighten the tank bolts evenly on both sides to pull the tank down straight and prevent stress cracks in the porcelain.

FAQs
What specific tools will I need to adjust the fill valve float?
For most modern fill valve adjustments, you typically won't need specialized tools beyond your hands. Some older or specific fill valve types might require a flathead or Phillips screwdriver to loosen a lock screw or a pair of pliers to gently turn a locking nut. Always have a towel handy for any minor spills.
Do I need to turn off the water supply to the toilet before adjusting the float?
While not strictly necessary for simply adjusting the float, it's a recommended safety measure, especially for beginners. Turning off the water at the shut-off valve behind the toilet prevents accidental overflows if you inadvertently displace a component. Remember to turn the water back on fully after testing your adjustment.
How do I know if I've adjusted the float to the correct water level?
The ideal water level is typically about 1 inch below the top of the overflow tube in the tank. After each adjustment, flush the toilet and observe the water refilling. The fill valve should shut off completely once the water reaches this level, and the toilet should remain silent without any trickling sound.
What should I do if adjusting the float doesn't stop the toilet from running?
If adjusting the float doesn't resolve the constant running, the problem likely lies elsewhere in the fill valve assembly or with the flapper valve at the bottom of the tank. The flapper might not be sealing properly, or the fill valve itself could be faulty and require replacement. Consider checking the flapper for wear or obstruction next.
