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.

Hi kkellerrurse and welcome to The Plumbing Page at AskMeHelpDesk.com. You're re responding to a 8 year old dead thread so I gave you one of your own. Are you on city sewer or a septic tank?
If the future please check the date before you post. Thanks.
Before I started to break up the slab I'd get a Sewer-Cam and see what's down there.

I was also told by this plumber that absolutely nothing but water should go down the drain... no plumbing chemicals etc I am non fan of putting harsh chemicals in your drainage system, Besides, they only work in TV ads. However they won't eat up your pipes and what else would you put down a floor drain besides water?
You can snake the FD and clear it but I'd still like you to Sewer-Cam the drain line.
Good luck, Tom

I am pretty much with Tom on this but have a few questions. Why is the floor drain so active, what's draining into it? Did he rod it or did he use a camera?
