DWV Layout Bath & Laundry


I am moving a bathroom and laundry room 60 feet to a new location. I will be able to slop the new 3" drain1/4" - Ft, but will have a minimum vertical distance to bring Vents vertically (45 deg or about 6 inches to the bottom of the slab. I am posting a ISO layout I hope will qualify as a circuit Vent. If not, how can I make it a circuit vent for the laundry, shower and WC.
Thanks for any help you can give me,

Laundry sink and washing machine don't use a cross or adouble sanitary T use two seperate connections

If you put the washing machine trap 6" off floor with a 24" stand pipe and the laundry sink 19" this will seperate and reduce a possible backflow situation.

I will ask what did you use to make this drawing it's really nice.

Thanks for the input Javiles, Virginia I believe is under the same code as Florida IPC. I'm not a plumber, but have studied the code a lot. I think this would qualify under circuit venting? As stated in my first posting due to the depth of the sewer trying to individually to vent the shower would be a challenge. Any input you can give me I would appreciate

I wish I could draw it out for you, I just downloaded the Sketchup 8 have to learn how to use it, you have a vertical vent with a side inlet 90 this fitting will not pass. I will try to draw it tonight. If you lay that 90 on its side run over to the washing sink area the vent over buy offsetting the stack. Structure permitting of course, now if you take that 90 and put a sanitary tee on top of it instead of that side inlet 90 you’ll be OK. Also the washing machine line must be in 3” up to the receiving tee, after the tee you can reduce your vent to 2 inch. And you’ll need a clean out at the base of that stack. And the waste arm for the shower may be too short .Circuit vent is allowed you can set a series of fixtures in place and have them circuit vented or re- vented, it’s the placement of the fittings in the ground roughs and top outs that you have to follow approved combinations.

Hi Javiles, thanks for the input I reread on the side inlet quarter bend "The inlet is permitted to be placed in a horizontal position only where the entire fitting is part of a dry vent arrangement." oops. I will have to leave the cleanout at location it's at now, it's the only place it will be accessible with 18 inches at the front and that's about the only place I can bring up 3 inches without increasing the width of some walls. The code seems to say the washer and sink can be a 2 inch horizontal drain. I am sure somewhere else in the code it says it must be ...
Thanks a lot, Norm

Not really sure where your getting the information on the code under the IPC dry vents are a no no you have a wet vents or a wet bend configuration you have 2 fixture on that line thatís considered a branch, you cannot feed a branch into that fitting,, fittings are designed with ease of flow , I understand your reading something and interpreting as you read it, but there is a lot more to these combinations than whatís in the code book. Youíre adding an extra vent at the rear of that trunk line when you can go with one. You can vent the shower sink a washer off one vent. Thatís the beauty of the wet bend you can vent a series of fixtures off one vent you also have a blind area (no clean outs) , the clean out can be placed anywhere on that vertical stack within reach .it does not need to be at the bottom, I will give you an example where I can use that side inlet 90.. in a commercial drain line picking up the grease lines, that 90 would be used as an indirect drain in to a dry vent thus wetting it, Running no more than 48 inches trapped picking a floor drain or a ice machine drain run off, and even then itís still questionable, at that point it would be up to the building official processing your drawings or the field inspector. You can run 2 inch on a washer if your connection is in the existing branch drain that is in 2 inches .new locations or installations require 3Ē. Look what you have will work fine if no inspection is required.

Javiles I meant the oops for me! I do not know what I'm doing with plumbing and I need all the help I can get. I want everything I do to meet the code and exceed it if possible. I know my inspector will definitely want it that way. I am retired electrical engineer and remodeling my house doing all of the work except the physical. Like I said, I need all the help I can get on the plumbing. I appreciate anything you can suggest I've got a lot of physical restraints I will try to post the portion of plans including the bath and laundry. I am having trouble posting images to the diy.
