I have an empty property in foreclosure in the city of Miami with average water bills for the last 5 years of about $50 which i could manage. All of a sudden without leaks or remodeling i got a $2000 followed by $ 6000. I went to the city several times and followed their instructions to test the facility; I was never told I needed a city certified plumber. A plumber inspected the property in and out over a period of several months and never found any problem. I requested a court day and lost because my witness was not a city certified plumber. A $ 8500 lien was placed on the property. The city cut off the water in my 4 other tenant occupied properties in Miami with water payments up to date until i pay the 8500 lien. Tenants are now facing hygienic and health problems. Is it legal ?
