Also, be sure the toilet is square and aligned with the wall. Use a level to level the bowl, adding shims where necessary. You may need to warm it in the sun for awhile until it is pliable. Also, if the wax ring is cold, it will not properly seat. If you don’t feel this, the flange is set too low and you will not get a good wax seal between the flange and the horn (waste outlet). It is important you feel the toilet being pushed into the wax ring. Using the bolts as guides, lower the bowl into place over the flange. Position the new wax gasket on the flange, with the bolts “molded” into the wax to hold them in place. Set the new floor bolts in plumber's putty and insert them through the flange, adjusting the bolts so they line up with the center of the drainpipe.
Step 3 - Set the Floor Bolts and Install the Wax Gasket Put a small level on the flange while tightening to be sure it is level. Now you can finish tightening the screws that hold the floor flange to the floor. You may need to use a piece of finished flooring material if the floor has not yet been installed. It is always best to install the finished floor so that it runs underneath the toilet.
Position the floor flange so the underside of the flange is at the level of the finished floor. It’s easier and less expensive and it works fine. This goes underneath the existing flange with the toilet bolt through it. There is a repair flange, called a spanner flange. If its cast iron, you need a fernco fitting, cutting the cast iron with a sawzall and replacing the pipe with PVC. It requires a coupling the size of the pipe, either three or four inch, a short piece of pipe, and a new flange. It requires cutting the existing drain pipe below the flange and replacing the flange and the pipe.
#How to install toilet bolts to floor cracked
If the old flange is cracked or broken, replace it with a new floor flange.ĭoityourself’s plumbing consultant Mark Vander Sande adds, “Replacing a flange is not an easy thing to do. Remove the old bolts from the floor flange and scrape the flange clean to prevent leaks at the base of the new bowl. If you’re replacing a toilet, you need to scrape up the old wax gasket. The closet bend and toilet floor flange must be roughed in first. Step 1 - Rough In the Closet Bend and Toilet Flange Clearance from the front of a bowl to a wall or fixture should be 21-inches. The minimum side distance allowed from the center of the toilet bowl to a wall is 15-inches, and 12-inches from the center of the bowl to a bathtub. If the toilet is situated on a branch drain, it cannot be upstream from the sink or shower. This is possibly the single, most troublesome fixture to install as it requires its own two-inch minimum vent and a drain of at least three-inches in diameter. Pipes required include a cold water supply stub out with a shutoff valve and flexible tubing for above the valve. This debris can cause problems in your sink faucets and other plumbing trim. Hint: When turning the water back on in your home, always run the outside hose valve or flush your toilets to bleed dirt and air from the lines.
