Okay after 7 years in my house I am finally re-doing my basement. It was finished but the previous owner didn't think the project out very well and he cut a lot of corners. It's taken me several months but I have completely removed everything he did.

I assumed the plumbing was roughed in but when I gutted the bathroom I found out that he jackhammered the floor and ran the plumbing himself. Anyway under the shower there was a huge hole in the slab (DAP OUT?? ), the vents ended in the wall with some sort of spring type vent, and the overall placement of the drains is not really condusive to how I want to redo the area. (BTW should the dap out be filled with gravel or something? should I leave it?)

What I am going to do is rent a jackhammer, remove what he did and complete the job correctly. I haven't removed the floor as of yet but it appears that he tied the tub/shower, toilet, sink, and wet bar sink into the floor drain in the utility room. Is this acceptable? I have not had any problems other then the wet bar sink draining slow (I have now removed the entire bar so this problem is gone).

I have a wall in the room above so I will be able to vent the new fixtures through the roof. I assume this is better then the current spring type in wall vents?

I planned on venting the sink directly up through the roof and making a loop vent for the shower that ties into the sink vent. I assume the toilet does not require a vent. Is this correct?

Anything else I should look out for?

I want to do it all myself and then have a plumber look at it before I fix the slab.

Hi Gary,

I could help you better if you would tell me what fixtures you plan on installing and in what order. Toilet , lavatory, shower or tub? And bar sink? The original rough in was roughed for a bath tub, (the dap out) but instead had a shower installed over it. You shouldn't have to vent the shower if you connect to the lavatory drain and let the lavatory wet vent it. Running the vent out to the roof is always better then mechanical vents. Please give me the details of what you're planning to unstall and I'll get back to you.
Regards, Tom

Sorry I guess my questions were a little confusing.

The wet bar is gone but I am going to bust up the floor to remove the plumbing under the slab.

The layout will be shower, toilet, tie into the floor drain and then the sink. That's why I thought I would need to have a vent off the shower and loop to the sink that will then vent to the roof.

Hi Gary,
If you were to tie the shower drain into the lavatory drain the shower would be wet vented and you wouldn't have to revent it. If that's not possible then go with the revent. Good luck, Tom

Thanks Tom,

I really appreciate all the time you spend on this board answering the hundreds of questions that you do.

It's great to have the ear of an expert.
