Friends, my daughter is in need of a plumber or someone who knows plumbing well enough to help resolve some leaking pipes in her shower and sink. This is in a mobile home, and she's just been through a major overhaul of her tub and sink due to another leak which created a nightmare of mold and weakened supports. If anyone can lend a hand, it would be much appreciated... please note, we're trying to do this on the cheap, because money became scarce after doing all the repairs from the leaking tub. :(
