Hi,

I'm roughing in my basement. I have a lavatory on the other side of the wall from a washing machine. Can I plumb the lavatory into the stack? Of the washing machine (the pipe the washing machine discharges to)?

Thanks.

Are you asking if you can drain the lavatory in the washers vent stack or the washer stand pipe?

Oops, I mean into the standpipe.. .

Hi,

Here's a drawing of my basement. I have nine fixtures to rough in (10 if you count the floor drain in the laundry room. The purple line headed off the edge will go to an ejector pump in a window well. I started laying it out but don't think it is too efficient. Any help would be appreciated.

Thanks!

If I could get the program you used to draw this I could draw it out how I would do it I just can't explain it in words you know I would have to show oyu on pic while I explain in words

I don't know much about this, but from the old drain systems that I have worked on, I have noticed that anytime there is a 90 degree turn (or right angle) that seems to be the place that gets clogged. Is it possible to have more of a " Y " at the intersections by connecting all three intersections at a point between lav 2 and lav 3? If you tie the two lavs together along with the floor drain at that point, it would give only one location that you might have to access at some point in the future if some object were to get caught in there. If you have a capped access or clean out of some kind to the drain at that point, it would be a lot easier to snake out any of the three lines leading to the main drain. Just a thought, and I'm curious to hear what others think.

This would lay out much better if you ran a straight line under the wall that runs North and South in the picture and then branch off with combos under their respective walls to pick up the bath with Lav 1, BT_1 and WC_1 in it and the laundry room.

Thank you. Does this make a little more sense? My fixture unit count is around 18 or 19 and I think I can do a 3" main building drain unless the code makes me go 4".. .

iamgrowler · Nov 16, 2007, 05:31 AM

That's pretty much how I would lay it all out -- A 3" drain should be more than sufficient for this portion of the plumbing, if Lav_1 is in a vanity, you should come up there with a 3" Clean Out Tee for a line clean out and then bush down the top of the C/O Tee to pick up the lav drain.

Also, if the line you are pumping this to has another water closet connected to it, then the line should be 4".

On your BT-2 how will you have access to the fixture to the back? I like the rest... Be sure to have cleanout runs in each circuit as it's cheaper NOW than later! Hope it helps...

plumberjames83 · Nov 16, 2007, 05:10 PM

The second pic is how I would run it just be sure to have vents right especially after the toilet

shavetail · Nov 16, 2007, 08:04 PM

Thank you for all the help. I've attached the latest drawing. Desgrunner got me--I had one tub blocked by another, so I switched BT-1 and WC_1 around.. .

I also hatched the north wall and two other walls that are load-bearing concrete walls, so I can't do much with them, or at least I don't want to try to stick any plumbing in them.

How far below finish floor should I stay with my 3" main line (what I'm calling the "building drain"?

All this stuff is going to run to an ejector pump in a 30-gallon basin that I'm going to stick in a window well.

LAV_1 is in a vanity so I could hide a cleanout in there.. .

Any other comments would be appreciated.

Hi I asked another question about roughing in a basement last night and its gone! Did I make someone mad or do something wrong? It was there last night, I checked after I posted it.

N0help4u · Nov 17, 2007, 06:38 AM

I noticed another post I was replying to disappeared as well. Have no idea why.

speedball1 · Nov 17, 2007, 06:41 AM

It's still there on the first page. Hey! Even if ypu pissed someone off I wouldn't allow your thread to be deleated. Did you see your answers" No? Then I'll bump it back up to the top. Regards, Tom

speedball1 · Nov 17, 2007, 06:42 AM

Bump!

shavetail · Nov 17, 2007, 06:46 AM

Tom, I put another question on though, with a new drawing. That's the one I can't find anywhere.. .

Then it didn't upload. Try again. Regards, Tom

Thank you for all the help. Here's my latest drawing. I switched around WC_1 and BT_1 so that BT_1 wasnt' boxing in BT_2 (thank you desgrunner).

How far below finish floor should I stay with my building drain (the 3" main drain)?

THis is all going to an ejector pump in a 30 gallon plastic basin in a window well.

Any comments would be much appreciated.

Thanks.
