If no hardware was provided, use wood screws or cement screws, depending on your subfloor material. Slide the
The flange is also anchored to the subfloor with a rust-proof screw keeping it stable and free from movement. A wax ring mounted on the closet flange creates a watertight seal between the bottom of the toilet and the closet flange, preventing any leaks, odors or sewer gases from escaping the fixture.
Use Tapcon anchors or a similar type of masonry/concrete screw to fasten the toilet flange to the concrete slab.
The toilet flange, also known as a closet flange, is the part of the toilet that secures the unit to the floor and connects to the drain pipe. Usually made of PVC, rubber or metal, this piece is circular in shape and usually secured in place with a few bolts.
WIth an anchor, the specific one you choose will dicate the diameter and depth of the hold. Once the hole is made, you may need to vaccum out the dust, then slide it in, set the flange, then use a brass or SS screw to hold it down. The screw expands the anchor to hold it down.
Check the flange bolt at each side of the toilet, using a pair of pliers or a small wrench. If a bolt is loose, tighten it slowly just until it is snug. Check the other bolt to make sure it is equally snug, then test the toilet for rocking. If it still rocks, proceed with shimming the base.
A flange screw with a serrated hex washer is an un-slotted hex head screw style with a unified thread pitch, and a flange that has serrations on the bearing surface side. These screws are designed for use in applications where vibrations can loosen fasteners.
See whether you can jiggle either of the bolts underneath with your fingers. If a bolt is loose, simply use a socket wrench to tighten the nut until you feel some resistance. (Beware of overtightening — you don't want to crack the porcelain of the toilet itself.)
If your toilet is creaking or wobbling, you may need to replace the flange. For a plumber, replacing a toilet flange is a quick and easy job. Replacing a toilet flange costs $145 to $165 on average.
Position the new toilet wax ring on top of the toilet flange, ensuring it is centered. Want to know more about choosing the correct wax ring size, crucial installation tips, and other frequently asked questions? Check out our Oatey 101: Wax Rings blog.
A: No, you must remove the toilet to access and replace the flange.
A best practice is to install the toilet flange on top of the finished floor. If you install the toilet flange flush with the finished floor, or even below the finished floor, leak paths will form, because the flange won't be at the correct height to accept the horn at the bottom of the toilet.
Set the brass ring on top of the rubber gasket and tap it down gently with a hammer. Use a ratchet wrench to tighten the four stainless-steel screws, securing the flange to the floor.
In Petro and chemical industry for flange connections Stud Bolts and Hex Bolts are used. The Stud Bolt is a threaded rod with 2 heavy hexagon nuts, while the Hex Bolt has a head with one nut. Nuts and head are both six sided.
Also called toilet bolts or T-bolts, closet bolts secure the flange to the flooring. They come in a range of sizes as well, commonly 1/4" or 5/16". Standard T-bolt length is 2-1/4", but extra-long bolts are available for when you need to go through multiple or thick layers of flooring.
If the pipe has a 4-inch inside diameter:
This toilet flange is designed to glue on the inside of the pipe or expand inside the pipe. Leave the old toilet flange in place and glue on the new one at the correct elevation for the floor, if it's plastic.
If your floor is not level, it can cause the base to wobble. If you over-tighten the bolts while the floor isn't level, it can crack your porcelain. A broken wax ring, the seal under the toilet, can also make the toilet wobble. Over time, wax seals can become worn out or damaged, leading to an unstable toilet base.
Typically, the toilet flange is mounted on top of the floor with the hub fused around the drain pipe. A wax ring is used to seal the gap between the flange and the bottom of the toilet. The toilet is bolted to the flange, not to the floor. They are usually made from PVC, rubber, or metal.
The most common culprit for a loose toilet is the flange or flange bolts. Looking from the front of the toilet, check the flange bolts which are situated on each side of the toilet. If the bolts are loose, use a pair of pliers to carefully tighten the bolts until they are snug.
