I think a plumber can help you... i had water coming from inside my walls before because whoever built my previous house had used two metals that corroded each other...have you turned your water off??
Omg i know!!! Not to scare you but mine cost $1100.00!! Does the estimate cost go toward repair cost?? What a mess!!! You cant go without water that long!! Is it all in the bathroom? If there is carpet, pull up the carpet to saw damage and mold underneath dynamoo!! It really sounds like it may be in the walls somehow, but i am no plumber!!! I was able to hear water dripping thru the wall!!
