How do I fix my leaking toilet from the bottom?

To fix a leaking toilet, you have to stop the water valve in the toilet. After that, take a close look at the leakage. Then tighten the closet bolts and scrap off the cap of the bolts using a screwdriver or putty knife. Keep tightening each bolt until your toilet leaking stops. However, if you are not sure of the process, it is better to hire a professional plumbing team. Otherwise, you may end up damaging the entire toilet system.
