My basement has no bathroom and now that I have added a home theatre it is much more inconvenient to run upstairs in the middle of the film (and for some reason it always happens at a highly dramatic moment).
So I was thinking about adding a bathroom. I've worked out a layout and here's where I'm stuck.
Joining the main stack for a toilet. Presumably I have to dig a channel, lay the ABS waste pipe at a slope, tie into the main stack and then make good the concrete floor. I think I have two stacks - the one I want to use (i.e. the nearest) services a bathroom upstairs (so toilet, bath and basin all vent and drain through this stack). Is there any problem adding to this? How do I tie into it - the connections from above are a bit of a mess and I'm worried about what the pipe will look like underground - could it be metal?
To dig my channel I presume I will need to use a concrete saw to cut the outline and then jackhammer the channel. I've never done this - any tips? Anything I need to know about when making good the concrete afterwards e.g. dpm, rebar?
There is an odd floor drain in the area for the new bathroom - I've never seen or heard water flow in this drain and when I have poured water down it it drains fine but I don't know what it drains into - not my sump. Any ideas on where this would drain or how I can find out?
The stack vents through the roof and as far as I can see all the drains for the upstairs bathroom use this one vent. Can I do the same? The drain run from the basin will be about 6 feet to the stack - is this too far for venting?
