In a five year old new home I am finishing the 50x 38 basement. Rough-in plumbing for a bathroom toiet, tub, sink drain and ejection pump basin has been installed with pump 2" discharge and dry air vent pipes capped off in ceiling.
1: Toilet and tub drain locations do not fit my plan therefore I need the breakup the concrete floor and realign these drains. Will I encounter any environmental gases when I cut up the concrete.
2. I intend to do RADON short test while working the concrete. I will construct a 6 mill poly 4 wall and ceiling tent stappled and taped for concrete dust control. I layed out the outline of the main drain pipe going into the ejection basin. I marked a saw cutting grid along the location to the existing toilet drain. I intend to saw a 4" deep cross grid aligned with the pipe at the toiet drain. The cutting grid is based on 2" squares. With this grid cut I should be able to hit the center with a sledge and break out grid ( I hope).
3. I cannot use jack hammer (without emptying the china closet upstairs) What do you think of this concrete removal approach? I felt that with the concrete around the toilet removed it will allow me to locate the direction of the rest of the piping so I can repeat the cutting grid marking.
4. With sufficient concrete working area removed I can design the plumbing layout for my 34x60 multiple shower head (6) shower and 4" shower drain. Also to be installed is a dain from 48' perimeter wall pipe run to the kithenette prep/wetbar sink. This drain starts a 16" slopping 1/4" per foot to dump into the bath room behind the shower at 4"with 2 cleanout along the way each after it turns the corner.
5. The ejection pump discharge pipe passes through the basin cover 90 degree elbow to a diconnect coupling then a horizontal check valve (as stated by the pump) turns 90 degree upward to a gate valve and into the capped (removed) discharge pipe.
6. The pump vent pipe goes upward to the ceiling to join the now uncapped dry vent rough-in that goes to the roof. Can this vent pipe be joined with a 2 Tee's at the ceiling with the other vent pipes (vanity sink, utility sink, shower bathroom drain vent and wetbar sink) into the single dry vent to the roof????
