Can I replace a toilet fill valve myself without professional help?

Yes, many homeowners can replace a toilet fill valve with basic tools. If the toilet still runs or ghost flushes, the problem may involve the flush valve, seals, or loose tank connections, which our licensed plumbers repair. We offer onsite diagnosis, professional unclogging, and toilet installation when repair isn’t practical, with upfront pricing and 24/7 service in Glendale Heights and nearby Schaumburg.

• Shut off the water and empty the tank.
• Check the supply line and tank bolts for leaks.
• If leaks persist or flush stays weak, call a pro.
