Call a Professional Plumber

Hire a licensed plumber when DIY fixes have not resolved the running toilet or you suspect a deeper issue like a cracked flush valve or supply line problem.

Why It Works

A plumber can diagnose problems beyond the flapper and fill valve, such as a warped flush valve seat, a cracked tank, or issues with the supply line. Professional repair ensures the fix is done correctly and prevents water damage from improper DIY attempts.

Tips

• Expect to pay $100-250 for a standard running-toilet repair (parts and labor)
• Worth calling immediately if you notice water on the floor around the toilet base, which may indicate a wax ring or tank bolt leak
• Ask for a written estimate before authorizing any work
