Hi all, I am new to this site and I hope to be able to get some help with a bathroom/laundry room reno. I Am looking to turn a spare bedroom and a bathroom into a single laundry/linen bathroom on the top floor of our house. (top floor consists of 5 bedrooms and a bathroom). We recently just bought this house that was built in 57 and many updates need to be done in plumbing/electrical. Electrical is no problem since I work in the electrical field but Plumbing is a new ballpark.

Can I get some help with some single line diagrams on piping routes and size??

I will provide pictures so you will better understand what is currently here and what I intend to do.

For now, here a paint diagram on what and where items will be located. Current have all exterior walls and ceiling exposed and have to open up the floor today. The current vent stack DO NOT go up thru attic nor thru roof, Your jaws will drop when you'll see where the current air intake for stack is to. Will post some real pictures when I remove some of the floor for laying pipes.

I need a simple line diagram on what size of pipes and how to route em for this reno. I look forward to working with you all to make this project a great success

THanks you kindly

Hi FYE:

Here is a line diagram of how I would pipe this...see image.

Understanding that you plan to remove the cast iron to the basement I would cut out the 4" cast iron and send up 3" ABS from the basement. The 3" will run up stairs, pick up the fixtures and then go out the roof 3".

I suggest pulling a 2" drain line off a 3"x2" wye BELOW THE FLOOR and run that up for the smaller fixtures. The toilet will be vented by the stack.

All vents connect to the 3" vent stack either in the walls or up in the attic..whichever you like best.

Vents pitch back toward drain at 1/4" pitch per foot (or so). Here, picture rain water flowing down the vents and falling into the waste line by gravity....make sense? All vents connect into the vent stack with inverted sanitary tee fittings.

Use dandy cleanout where you can access them in the future if needed.

Finally, I recommend using the washer drain box Speedball posted earlier...makes a real nice finish job on the drain/water. All fits iside the wall and connect to the box...see his image.

Do not forget to support the BASE OF THE STACK with an appropriate hanger...gets heavy with all these fittings!!

Let me know what you think...

Hi Mark, thanks for the nifty diagram This looks good to me and seems like I should be able to handle it with some guidance from the plumbing shop when I go get the supplies needed. Yes I will be printing this and taking with me to ensure I get the proper fittings.

Thank you again Mark, I will update this thread as I install or need additional questions asked, for there going to be more questions for sure.

I will be posting pics tomorrow of basement nightmare plumbing and what I intend to do down there as well. Was hoping to get pics and post them today but was toooo busy re-framing the walls studs to 2x6 and running all the homeruns for all the top floor electrical back to panel. You should get a good chuckle out the basement plumbing pics especially the high rise toilet
