I just bought a mobile home and learned that the recently updated bathtub does drains under the trailer instead of into the sewer line. There is also no water coming out of the bathroom sink, but the toilet works fine. What could be the issue and how would I go about fixing it?

I have already checked to make sure the water is turned on for the sink and have been told that I may need to reroute the pipes to attach to the sewer line.

It just drains onto the ground?

So I assume no home inspection was done, right? You may have recourse in court since this remodel was done outside of code and is totally illegal and unhealthy. Did you use a lawyer at closing?
