If you're updating a bathroom, you'll need to know how to replace the toilet. Apply a wax seal over the floor toilet flange to prevent sewer gases from entering the room. For extra protection, put a second bead of plumber's putty to seal any imperfections between the floor and the bowl. Place the new bowl firmly and evenly over the seal and bolt it to the floor. Attach the tank. Cut your toilet tube supply to connect the tank to your water supply. Fill and tank and flush away!
When installing counter tops, scribe the the new splash guard to the wall with a compass. This will transfer an exact copy of the wall to the splash plate.
If you suspect your toilet is leaking, but aren't sure where, add some food coloring to the water in the tank. If you see colored water inside the toilet bowl, suspect a defective flapper that needs to be adjusted or replaced. If it shows outside the toilet near the back, suspect a faulty tank-bowl gasket. If you see any water on the floor near the base, check for a faulty wax ring.
