I have a three basin basement sink that is cast iron and cement. It is very heavy maybe 800 lbs or more.I am not sure. The stand it was on has deteriorated. How do I get this out of the basement intack. I would like to use it in the back yard for flowers or vegetables. Any ideas on how to do this? solutions? I tried to insert an image but could not. The sink is six feet by two feet, each section is two feet. HELP!!!!
