I need a good investigative PLUMBER! Just got my 2nd $89 water bill---crazy--Metro says my meter is working fine. So must have leak on "my side" of the line.Of course! I can't find any sign of leak or hear anything. I need someone who is a genius at finding hidden leaks. I simply can't keep paying these crazy bills. Until a year ago, my bills averaged about $20/mo. Nothing has changed. Other than my bill saying I'm using triple and quadruple the amount of water I've always used. HELP---I need someone who can find this mystery!
