So every year...usually twice a year...THIS HAPPENS!
I was told I could not use Drano(but I have..didn't work). I was told they won't replace the
elbow join under the sink(cause I'm pretty sure since this room has been an art room for the past 20+ years..it has some gunk in it that will NEVER come out). I don't put anything down it that is questionable..but have to pay the price(cause Lord only knows when they'll come and "fix" it??!?) Any tips? Ideas? Money to have it all replaced??? :) ha ha
