How to Fix That Leaking Toilet
The main signs of a leaking toilet are water pooling on the floor and a possible smell of sewer gas. The steps you need to take to repair the leak are as follows:
- Shut off the water supply valve and remove the water line that connects to the tank.
- Loosen the bolts around the base of the bowl – if they are corroded, cut them off with a hacksaw.
- Lift the bowl away and set aside. Clean the old caulking and debris off the floor and stuff a rag in the pipe to block sewer gas.
- Look for a possible broken flange, any signs of rot around the flange or a wax ring failure.
- If the flange or wax ring is broken, replace with a new one and if the floor is rotten, install a flange support bracket to transfer the load.
- Reset the toilet by aligning the holes with the bolts and pressing down to seat the wax ring. Do up the nuts and caulk around the base.
