Water leak from 2 floor bathroom
We have a full bathroom . It is on the 2nd floor.Full tub, sink and toilet. We had to turn water off to it due to a major leak. Between the floors are the pipes to the tub , sink and toilet. <I think> On day my step son was sitting under the leak, before we knew we had one. The wall and part of the ceiling fell on him. At once we turn off all water to there. But Now how to fix it. Only can get to a few pipes from down stairs where we lost the wall. The rest of the pipes are between the floors and Maybe part of our bed room closet. With out taking out tub , sink and floor out of the 2nd floor bathroom, How can we fit this leak?
