Hopefully someone can help me here. I am in a newer home (3 years old), and have just found out that the upstairs bathtub drain pipe leaks. It is the 4" PVC pipe that I noticed water leaking out of after draining the bath water of our newborn (and happened to go into the basement (unfinished thankfully!). It is a very small trickle, but obviously something that has to be dealt with. I am wondering if there is a way to find the leak without making a bunch of cuts in the bulkheads and walls (which is probably the only way to find it).
A little insight would be great!
Thanks a ton
