After talking with Daniel. He showed me the small hole in the ceiling an the bottom of the steps. I felt up in to the hole an found that is the bottom of the trap for the shower. I went up into the master bath an found cracked caulk around the shower base. I then checked the drain an found nothing that looked out of the normal. I ran the shower for about 5 min an there was no leak every thing was dry. I filled the shower pan up then pilled the plug an still no leak. Daniel did say that it only leaked once an hasn’t done it since. I questioned him some more an found that the night it leaked his wife/girlfriend was rinsing down the shower with everything I have put together I think it may be water getting around the shower pan an leaking thru that way. I have given estimates to replace the old shower an valve and a few others estimates.
