Question washing machine question

ok, so I'm running the drain line to my new washing machine.
I know I have to put a trap and a vent on this drain.

it seems like it will be hard to fit the trap in a 16" stud spacing.
Is there something I'm missing?

also, can I use an air admittance valve here? My code does
allow air admittance valves. If I do use one, it has to be
accessible. can someone recommend a good way to locate
it so I can get at it?

thanks!

If you have enough room in front of your washer to pull it out and leave it out a few inches, you could just tuck both of these things behind the it.

If you can follow this the way I describe it;



Pass through stud with a 2-9/16" hole, hug 2" 90 through the hole turned up towards ceiling. This hole should be anywhere from 16" to 19" from the floor.


Short piece the tolerance of the fitting hubs, 2" tee, 2" X 11/2" bushing in top of this tee.

Out of front of tee, short piece to tolerance of hubs and connect trap 90 to this turned down.


Set washer box or stand pipe about the same or a little above the height of washing machine. Standpipe should be a minimum of 24 to 30 inches. Nothing less than 2" piping should be used.

Off the top of tee, run 1.5" piping as high as you can go with a female adaptor at top.

Buy a cheater vent since you said it is legal in your area and install in female adaptor.


It's a tight fit......but it will work.

Exactly how thick is this wall? If it's just a typical 2x4 stud wall, you can put everything in there except the jiffy vent. And the vent can go in the box if you're willing to improvise a little.

A picture can tell a thousand words.

By keeping the trap as close to one side of the stud, you can off set from laundry box to the p-trap using 45 degree elbows, I do this all the time, then all you have to do is drill the hole through the other stud as shown, pick up the vent and then to the drain.

Looks good. I suppose the jiffy vent could go someplace else. But he would have to have access to it.

If legally yes as long as it's 6" above the flood level rim on the laundry box.

I guess he would either have to find a tall laundry box or he could use two 45 degree elbows and bring the jiffy vent out of the box and put it up in the air like the exhaust pipe on a semi. I suppose you might say I'm 'thinking outside the box'.

wow, quite a few replies.

it is a 2 x 4 stud wall. prefer to not cut through stud if i can avoid it.

I understand the Tee and the 1 1/2" vent up. I have two questions though:

1) why do I want to use the two 45 degree bends under the laundry box? Is this required?

2) do I have to go 6" above the flood rim w/the cheater vent? for my kitchen sink, I am able to put one of these under the sink, below the flood level. I think I can get it up higher here, but just wondering.

thanks for the replies!

The two 45 elbows are not required, I use them only if your limited in space, usually the outlet on a laundry box when mounted between the two studs makes it hard to line up with the trap and in that making it impossible to to get everything in the wall. without either moving a stud and cutting a huge hole in one stud to make the trap fit.

You can always put the studor vent behind a removable panel.

Yes he can.

After you mount the box then you can see where the panel will be, the panel is a requirement I'm sure by code, do to the fact the device is mechanical and it need to be accessible, would need access to it if it went bad.
