Questions and Answers for Oatey 4 in. PVC Twist-N-Set Open Toilet Flange

A:  Go to the next size up the head will fit perfectly.

A:  I used Tapcon 1/4 in. x 2 1/2 in. Worked perfectly.

A:  While there isn't a recommended size, try using the next size up 1/4" x 1-3/4".

A:  I used the same size Tapcon, but hex-head, and inserted a concave washer under the head of the Tapcon. I actually made the washers by denting them to make them concave.

A:  Good question. The bottom of this is tapered, So you can screw the black seal as far up as you need unitil it fits snug. Then you can screw the top of the flange down until it is at the level you need and it fits tight in the pipe. It's a real neat setup once you get a good feel for it. I had an old (80+ years) pipe that was totally rusted away with no flange left and this worked perfect. Once it is tight at the level you need just screw it down to the floor and you good to go. Good Luck. Dwayne

A:  The barrel length is 3-3/4".

A:  That should work; I think the portion that goes into the waste pipe is 4 inches. I also used a Fluidmaster "Better Than Wax Universal Wax-Free Toilet Seal," which comes with several rubber seals to make up the difference.

A:  1" should be ok. It depends on the effective ID of the pipe since the threads are tapered. It's worth a try.

A:  I don't think you'll have enough room if you leave the original sleeve in place. It needs four inches, inside dimension.

A:  This is a slip in insert flange

A:  Yes! Sounds like you have exactly what I had going on. I had an 80+ year old flange that was so rusted the actual flange was GONE, This worked perfect. I had a cement floor and it has to be screwed to the floor to secure it when done so I had to use cement screws, But use whatever works for you. Good Luck. Dwayne

A:  Should. Since you will screw the PVC down into gasket to expand outward into the inside of existing drain to create a tight seal You might need to play w placement of gasket to ensure a snug fit You will get a bit dirty And then screw into finish and sub floor to ensure it wont rise up

A:  Shouldn't be a problem. There are two sets of bolt holes.

A:  Absolutely. It is tapered at the bottom and the black seal can be screwed up until it fits tight inside the old pipe regardless what type of pipe it is and then just screw the top of the flange to the position you need and you are set. Good Luck. Dwayne

A:  Yes. As long as there is room to turn to toilet. When you take off your old flange installed your new flange . Dont put the wax ring . And give it a dry test run . Don't for get about the water supply line. It will have to made longer. If your happy with its new location. Bolt it down and add the wax seal. Its very east to do.

A:  You can mount this Flange in any direction but need to make sure to fasten to the floor with the appropriate fasteners.

A:  remove the gasket and then hit it in w/ a mallet, it'll work. My cast iron pipe is 3.5, I made it work. No one makes 3.5 anymore.

A:  The neck on this Flange will be 3-3/4" OD on the 4" Flange and approx. 2-3/4" for the 3" Flange. These won't make a seal if your opening is 3-1/2".

A:  remove the rubber gasket and then hit it in w/ a mallet. hit until it goes in as much as possible, then put screws and everything else. the hole for mine is 3.5 and it worked. You might need 2 was rings, 1 XL and 1 normal, that way it wont leak. I looked around at other companies here in town, and none had it, they dont make exactly for 3.5,, have to make it fit.

A:  If you position the flat heads of the bolts in the narrower channel of the Flange and turn them 90 degrees, then place a washer and acorn nut down over top to hold them in the upright position, the bolt will remain secure and in place.

A:  i used the everbilt sold by HD and they worked fine
