I am trying to install a tub in my basement on a concrete slab. I already have a drain pipe sticking out of the concrete about 9 inches. Looks like concrete was filled around it at a later time because not smooth like rest of slab. Is there a way for me to tell if a P trap is already been installed under the concrete other then breaking up the concrete to see. The pipe is currently sealed at the top.

I would love to not have to break up the concrete if I don't have. Any suggestions to seeing if there is a p trap already installed?

Thanks

Matt
