Here's a question for the plumbers. I have had a similar problem with my floor drain downstairs for the past almost 8 yrs. It does get worse and more sluggish at times and that is when I call out a plumber. This past guy that was here explained that he believes my drain is broken where the drain line meets the stack. Of course then he explained how a fix would include busting up the concrete and replacing or relining. Honestly I feel as though he was trying to get more out of me by suggesting this. Now it is my understanding that the main drain can lead to a drywell which may explain why he thought it could be a break. Any advice? I was also told by this plumber that absolutely nothing but water should go down the drain... no plumbing chemicals etc. that they are all responsible for break down of drain pipes over time.
