The handle of your toilet may be getting stuck, which leaves the flapper open. Unless the flapper is closed, the water will continue to flow. You can oil, tighten, or replace the handle.

As soon as you notice a problem with your plumbing, call a plumber. Waiting too long will cause the issue to worsen.

Every plumber has different rates, and every job is unique. You need to call for an estimate on your repair.

Although there are unlicensed people who may offer to fix your plumbing, you should only work with a licensed professional. Doing so is the only way to guarantee they’re well-trained and have the experience for the job. You should also make sure they are insured.
