My toilet runs briefly whenever I turn on the bathroom sink faucet or shower faucet.
How can I fix this ?:)

Your water level's set too high in the tank. It wants to be 1/2" under the top of the white overflow tube when the tanks filled and the ballcock's shut off. Pull the lid and lower the level. If you need instructions click on back. Good luck, Tom
