OATEY 43501 – Frequently Asked Questions
1) Will the Oatey 43501 offset closet flange work on 3 inch pipe or does it need 4 inch?
Both. The 43501 fits inside 4 in. pipe or over 3 in. pipe, Sch. 40 DWV. So one part covers the two common closet bend sizes, and you decide at the joint: inside-fit on 4 in., hub-over on 3 in. Dry fit before you solvent weld, because once it is glued the offset direction is fixed.
2) How far off center will an offset closet flange let me move the toilet?
The 43501 gives 1.42 in. of offset, which is the margin you have between the drain pipe center and the toilet horn. That covers the usual framing conflicts, a joist or a rough-in that landed short. If your toilet needs to move more than about an inch and a half, an offset flange won't get you there and the waste line has to be reworked.
3) Why is there a metal ring on the Oatey 43501 closet flange and does it move?
The ring is steel and it rotates. That matters on an offset flange more than a straight one: the pipe fixes where the flange body sits, but the closet bolts have to line up square with the wall. A moveable ring lets you set the bolt slots and the screw holes independently of how the flange landed on the pipe.
4) Is the Oatey 43501 closet flange approved for use on a permitted job?
The 43501 is UPC and ASTM D2661 listed. ASTM D2661 is the ABS DWV pipe and fitting standard, which matches the body material, and UPC listing is what most inspectors want to see on the fitting under a water closet.
5) What material is the Oatey 43501 flange, ABS or PVC?
The flange body is ABS plastic with a steel ring, and it is listed to ASTM D2661, the ABS standard. Solvent weld it with ABS cement, not PVC cement. If your closet bend is PVC you need either a PVC flange or a proper transition, since ABS and PVC do not chemically weld to each other.
6) Does the Oatey 43501 flange come with a test cap?
No test cap with the 43501, that is what the "without test cap" in the name means. If you are setting this during rough-in and need to pressure or water test the DWV stack before the finish floor goes down, order a knock-out or twist-in test cap version instead, or plug the line separately.
7) How many screws hold an Oatey 43501 offset flange down and is that enough for a wood subfloor?
Six screw holes, across six mounting locations. An offset flange carries a side load a straight flange does not, since the toilet is not sitting directly over the pipe, so all six should be driven into solid material. On a wood subfloor that means catching the sheathing, and blocking under it if the hole is oversized.
8) Should I use an offset closet flange or move the drain line?
Use the offset when the toilet has to sit a short distance away from the waste pipe, typically a rough-in that missed by an inch or a joist you cannot cut. The 43501 buys 1.42 in. and no floor demolition. Beyond that distance, or if you need to shift the fixture in two directions, cutting in and relocating the closet bend is the honest fix, because forcing an offset past its range leaves the horn off the flange opening.
9) How much does the Oatey 43501 closet flange weigh for a parts order?
1.1 lb each. Light enough that a property manager stocking a few for turnovers is not paying freight weight on them, and each unit ships as a single flange, model 43501.
