OATEY 43521 – Frequently Asked Questions

1) Does the Oatey 43521 come with a test cap or knockout?
No. The 43521 is the version WITHOUT a test cap, so the drain is open once it is installed. If you still need to pressure or water test the DWV system before setting the toilet, order the test-cap version of the flange instead, or plug the line separately.
2) Will the 43521 toilet flange sit flush with my finished floor?
Yes. The flange is built to sit flush on the floor rather than proud of it, which is what you want under a standard wax ring. Because it fits over 4 in. pipe, cut the stub-up so the flange body lands level with the finished floor surface, not the subfloor.
3) Can I rotate the flange after gluing to line up the closet bolts?
The metal ring rotates independently of the PVC body, so you can spin it to land the closet bolts square to the wall and the screw holes on solid framing. Glue the body first, then set the ring where you need it.
4) Will the closet bolts fall through the slots on this flange when I set the toilet?
No. The metal ring on the 43521 uses patented bolt slot shelves that hold the bolt head captive so it cannot drop through while you are lowering the bowl. That is the main reason to pick the metal-ring version over an all-plastic ring when you are working alone.
5) How many floor screw holes does the Oatey 43521 have?
Six screw holes around the metal ring, spaced to work with the common toilet mounting patterns and to give you a chance at catching subfloor or joist in more than one direction. Combined with the rotating ring, that usually gets you two solid anchors plus the closet bolts.
6) How much does the Oatey 4 in. PVC closet flange weigh for shipping or a bulk order?
Each 43521 flange weighs about 0.833 lb with a volume of 0.074, which matters if you are pulling a pallet quantity for a multi-family rough-in rather than buying one.
