My house has mold in the bathroom and it seems to got in all the pipes in the house. my wife is 5 months pregnant and just drunk water out the faucet.

While mold can be...: particularly dangerous to an unborn child or infant, it's unhealthy for everyone in your home. Drinking bottled (or at least boiled) wateris a good idea, but note that mold spores usually enter the body thru breathing. Your entire plumbing system needs to be inspected, treated, re-plumbed--whatever it takes to clean it up. If you're renting, it's your landlord's responsible. Don't delay!
