Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. Will there also be a water heater? No washing machine? Is the access to a vent pipe?
Very good. I will make a list of rules to follow to help with the design of the drain pipe system. Typing now.
You can use a studor vent on the kitchen sink. The vent on the bathroom sink will be enough to vent the bathroom. There cannot be any drain pipes in the slab less than 2" pipe. A trap arm is the pipe that feeds the fixture and has a trap. The sink trap arm will be above the slab and will be 1 1/2 pipe. This pipe can be no longer than 5' and have no more than 1 1/2" of grade. The trap arm for the tub or shower will be in the slab and 2" pipe with a 2" trap. This can be no longer than 6' with no more than 2" of grade. The trap arm for the toilet must be minimum of 3" pipe and can be no longer than 10' with no more than 3" of grade. They connect together tub and sink first then connect to the toilet branch. Use Wye fittings or combination fittings for horizontal connections. Tee fittings can only be used for vertical connections. The kitchen sink must connect downstream from the bathroom group. The trap for the toilet is in the toilet and the traps for the sinks will be installed when the sinks be installed. The only trap installed under the slab will be the tub or shower. Any penetration through the foundation must be sleeved and sealed. The drain pipe must be tested 10' above the flood level rim which means that you would cap off the piping and there would need to be a 10' pipe filled to the top. This is often done where the pipe exits the foundation then 90 degree straight up. The sewer connection is made during another inspection.
There are quite a few little details that would be easier to explain in a phone conversation if you would like to do that and take some notes. I am going to be logging off for the night soon as I am on the east coast and it is almost midnight here. If you would like to do a phone conversation tomorrow or have any questions about what has been described so far I could certainly answer those too.
The only thing I do not see on the plan is where the sewer goes out. Do you know where that will be?
I can draw something on the plans you provided once I know about where the sewer will go out.
I am having trouble finding a file sharing site. I tried Wikisend but it will not work. I made a rough diagram. Still trying to share it.
I haven't heard from you. Was the information I provided helpful?
