I removed the P trap and pipe from the old kitchen and tried to reuse it for the new kitchen remodeling:
However, it's leaking water at the connection from the white pipe to the metal P trap:
I even used a new washer. What I realized is that I can only push the white pipe into the P trap for like 1/2 in. But when I tighten the nut, the plastic pipe is stil quite loose. If I pull it out by hand, I still can separate it.
My questions are:
Is this installation done correctly? Anything missing?
Did I use the wrong washer or wrong pipe? This is just 1/2" right?
Maybe the whole thing is bad. Should I replace the entire P trap and pipe set for the new remodel?
I played around with the same setup at Home Depot and it's very tight when I tighten the nuts. I mean I could not just yank out the pipe easily.
