It's a zurn, or at least the grate says zurn on it. I can feel a little flapper with my finger, so I think it is a backflow preventer. I think it is somehow inserted in the floor drain as the second pic seems to be of the same type drain but with the bfp removed. I reefed on it a bit, but it didn't budge. Is there a trick or do I just get rough with it?
No announcement yet.
Anyone know how to remove this floor drain backflow preventer?
