What Happens When My P Trap Won't Go On?

What happens here

Begin by examining the existing plumbing setup under the vanity sink. Identify the tailpiece extending from the sink drain, the water supply valves, and the wall drain outlet. Attempt to connect a standard 1.25-inch P-trap to the tailpiece. The video demonstrates that the 1.25-inch P-trap does not thread or fit over the tailpiece, highlighting an unusual manufacturing tolerance or design. This is noted as a 'first-time fail' for this type of drain.

Goal: The presenter identifies a common problem where a standard 1.25-inch P-trap does not properly fit the tailpiece of a vanity sink drain, which is an unexpected issue for a laboratory drain.

[Applause] all right so this is what we're looking at this is the bottom of a vanity sink okay sinks up here this is the tail piece that comes down you got the valves back there and you've got the inch and a half drain outlet that goes into the wall well connecting a p-trap up to this sometimes you use an inch and a quarter or sometimes use an inch and a half but check this out this inch and a quarter actually will not go up there and so i've actually i've never seen that especially on a lavatory drain right on a kitchen drain yes on a laboratory no i've always been able to put an inch and a quarter on there and you just can't you literally cannot put it there so i don't know if it actually is this style of trap this particular p-trap or it is something else it's i think that it's this i think that it's not a hundred percent brand name and that is what the issue is they actually just didn't make this to a spec that this trap will fit so with the inch and a quarter not fitting we're going to bump this up to inch and a half you can see there's all kinds of play right
