never tried this before, want to install stainless steel sink, but, cant get the old metal rimmed sink out ( my husband put that in a few years ago). tried to loosen metal rim with a putty knife thinking caulk was stuck like glue (it is white, so I am assuming he used caulk)- but no luck - looked on the internet, no luck, only read i was lucky the sink didn't drop on my sons head who is trying to help me get that sink with the sprayer i have my heart set on. (I don't remember his dad using any 2 x 4 to keep the porcelain sink from dropping into the cabinet - saw that on the internet also) - So reconnected the water lines and drain pipe back to the old sink- and walked the new sink back to the barn - any words of wisdom?
