    started a topic Basement Roughin, yet again.

    Basement Roughin, yet again.

    Reworking some old clogged cast iron that used to have galv above it. Tying into existing 3" CI with a hubless to ABS. Here are some pictures from both sides. Currently dry fit, not yet glued. From the main line it goes floor drain, riser, W.C., Tub, Riser. The far 3" will dry vent above where the washer attaches. The sinks on both floors will tie in with dry vents on the uphill side and all meet up in the attic (overkill). Once set this will all be bedded in sand prior to re-pouring the slab. I'll be leaving access through the wall for the bath tub connection.

    The turn along the wall will catch a washer, will be vented and tied in above as it will be too far down the wall to just wet vent. I'll be adding a clean out on this 3" riser as well. Stub to the right will be for the tub.


    First 3" riser. This will catch a utility sink and vanity on this floor and a kitchen sink and vanity on the floor above. Will add a 2" dry vent off the sinks to tie back in, in the attic.


    Floor drain to the right, will be catching condensate from a modcon heater.










    Have I done okay?

    Are you having it tested and inspected? Codes vary so your inspector should be able to keep your installation correct.

    I was wondering about that part. It will be a minimal annoyance, but I can have that line turn the corner and tie into the first or mid wall 3" riser, leaving the end wall riser to function only as a dry vent. Good?
    The exception is for a bathroom sink fixture only. Nothing else would be able to drain there.

    Looking for education and understanding here. Wet venting means whichever pipe is functioning to provide vent air also has a fixture draining to it upstream. When a fixture runs to a main on horizontal run where is it considered to be pulling vent air from? I was figuring on upstream of flow, yes? Nothing downstream is allowed to figure as providing vent air. So nothing upstream should feed into the vertical rise of the line providing vent for the horizontally feeding fixtures. It is allowable to have the water closet and toilet in line however?

    If one doesn't wish to wet vent the water closet and or the tub, at what point after the p-trap do you vent? In both cases there's the drain : p-trap : < 2' of run to the wye on the main : < 5' and 3' respectively to the elbow of the vented riser and 3' between the receiving wye's. Just guessing here as I'm trying to learn......... one would add a vent in between the p-trap and the wye for both, which could be tied together, and then brought up and connected to the riser above flood rim for the room as long as nothing further was draining from above. Yes?

    Did that make any sense? And no, I haven't set the concrete yet.

    I started plumbing in Ca. and had to really change my thinking after moving home to Mn. We can't use the heal outlets here at all but after it was all said and done I find this method easier than trying to stub up 2" vents all over the roof.

    Are you testing this & having it inspected?

    That's what I'm planning..... just kinda failed with the words there......

    Did you already glue that closet flange on?

    The way I understand it, the floor drain would get vent air from the first 3" riser, less than 5' away in 2". Yes? The sinks on the 3" riser will get a seperate 2" dry vents which will carry through to dry vent fixtures above which also drain to the 3" riser, all tied together in the attic before exiting the roof. The W.C. will will pull vent air from technically both 3" risers, yes? Less than 3' from one and 6' from the other in 3". The tub is the same but in 2". The second 3" will only catch one 2" line then dry vent above, tied in to dry vent lines above, tied to the other 3" riser in the attic, and then penetrating the roof.
    Good?

    Thanks breid, means a lot to me. The offset was needed to get into the new wall location which needed to be over a few inches. I've got it backfilled and just about ready for concrete..... Pictures later.
