Any help with the layout would be helpful. I would like to start tearing up the concrete this weekend if I can get this figured out.
I would like to put in a bathroom in my basement and move the laundry area. The existing laundry si where the proposed shower/existing floor drain is. I have attached a pdf showing my proposed layout. I would like to connect to the main sewer line at the existing floor drain. I have gotten quotes for just the rough plumbing from 2 plumbing contractors which I thought was high ($4000 and $2800) since I was removing and replacing the concrete in both. Both of them were going to use mechanical vents per their quote and I have believe they are acceptable per the code here (Michigan). WHat is the best way to layout the drain system and how would I vent it. The qoutes I received had 2 mech vents (I am assuming these are AAV's). The Laundry area will have a standpipe for the washer which will tie in the laundry sink drain. Does it matter which side? Any help would be appreciated.

Also, the main stack serves as the vent for the main floor bathroom. The bathroom is small so everything is within 6 ft of it. I don't believe there is any vent pipes from these fixtures, its vented through the drain lines to the main stack. I do have a secondary vent for the kitchen sink, its approx 15 away from the proposed dryer location to the right of the page.
Thanks

Hi , I'm a plumber in montreal and to try to help you, I would need a plan of your exciting area then I might be able to help you.
First the bigest connection is the toilet, all other smaller connections are before that, but your first connection should be a back water valve to prevent sewage water from returning in your house (if there's a flood)
Send me the plan at my email [email protected]
Like this I can send you a plan back
I'm sure it will cost you a lot less
