When a toilet is leaking from the base you may need to replace your toilet flange.
There are two options this step.
Pull up on the toilet and turn it so you can see the drain hole underneath the base.
Rest the toilet bowl on its side place it on a towel or cloth to protect the floor and attach the replacement wax ring to the bottom of the bowl this technique helps ensure the ring is in the proper position when placing the toilet over the flange.
To get the necessary clearance from the floor you can add a toilet flange extender which is quick and easy to install.
With the toilet flange in place you are ready to install the toilet with a new wax ring.
A toilet flange connects the bottom of the toilet to the drainpipe in the floor of the bathroom.
Most extenders come with long bolts which may be necessary if the flange is below the floor level.
If using a plastic flange ring be careful not to crack the ring by screwing the anchors in too far.
Screw the toilet flange onto the concrete.
Remove the old wax ring scraping wax from the toilet base and floor drain with a putty knife.
Tip the toilet on its side and install a new wax ring seal in the drain hole then carefully set the toilet onto the drain hole making sure the flange bolts come through the holes on the sides of the toilet.
