Laundary Room Relocation

[jr7]

Hey everybody I purchased my first house and I do have some DIY experience, but plumbing knowledge is a thing I lack. I have a finished 5th bedroom in my basement that is going to be the new site of our laundary room so I can make my 1st floor half bath larger. So I found the drain behind a wall in my basement and it does not go all the way under the basement floor. If you look at the picture, what are some recommendations for how to plumb the standpipe and p trap for the washing machine? I'm not exactly sure what I can do (that is to code) to tap into that drain. THANKS A TON EVERYBODY.

What rooms and plumbing fixtures are directly above this, by floor?

More info is needed to figure this out.

Can you provide an image with a sketch of the layout of the home, marking where this pipe is, where you want the laundry to be, and where known existing plumbing is?

Is the drain in the photo the main drain line for the house?
Does it exit via an exterior wall?
Where do you want to put the washing machine in relation to this pipe?

 

[jr7]

This is the main drain line exiting the home. This room is directly below the 1st floor bathroom which also held the washer and dryer. The pipe going off to the right is the drain for the bathroom that is located in 1st floor. It runs horizontal about 30 or so inches off the basement floor then makes a 90 degree turn up into the bathroom. All the drainage for that bathroom is tied into that drain line. This main drain line is located in the closet of that finished basement room, and the plan was to do away with the closet and put the washer and dryer right there. Basically directly in front of that drain. I was planning on leaving that main drain line and standpipe exposed I case I need to get to it again in the future. Directly above that main drain line in the ceiling is also the copper hot and cold water pipes. Also yes that main drain line does exit the exterior block wall of basement. Do u need further info?

I don't think you will have a problem but frodo will be along, he will tell you exactly how.
Welcome to the site and congrats on the first house.

Do u need further info?

If I understand this correctly, the diagonal branch of the wye just above the clean-out plug, 45's to vertical and is the main drain for the bathroom and fixtures above?

What is the height to the center of the plug above the floor?

 

[jr7]

that wye goes horizontal about 10 ft then makes a 90 degree turn up into bathroom. Also above the main drain is the kitchen too. The center of the plug on the main drain line for the house is about 26-1/2".

A washing machine can pump up to a certain height above the floor; not sure if it differs for different machines. So you should just need to figure out a safe height above the main drain, and use an anti-siphon valve for the drain connection. If you will be adding a slop sink to the room, you will need a separate pump for that drain.

 

[jr7]

My machine is very new and says it can pump up to 96". If I'm putting an anti siphon in it do I need a p trap? Also do I just tap right into that plug with the square in it? What other materials would I need for the drain. The copper water lines I know how to do, just not the washer drain. I do not want to add a sink in the room.

 

[Snoonyb]

This portion was clipped from this msg;"Yes you are correct about the drain that's goes to the right being for the upstairs bathroom.

Also a wye is by definition a 45 degree fitting and would need a 45 to change its direction to either horizontal or vertical, so this, "that wye goes horizontal about 10 ft then makes a 90 degree turn up into bathroom," is confusing.

 

[Snoonyb]

Another question.

Is there an evacuation sump and pump somewhere else in the basement, in the event of an overflow?

 

[jr7]

I see what your saying, but yes the wye ha a 45 on it and goes horizontal before going up. So is the anti siphon my best bet, and if so how do I go about installing one? Does it require a p trap and stand pipe with an air tight connection? Or does the washer drain hose get the anti siphons valve and it gets connected straight to the main drain line? If that's the case does the drain hose need to be a certain heighth?

 

[jr7]

Yes I do have a sump pump in the basement. In theory if I can get this plumbed correctly I wouldn't need to worry. I'm still looking for the answer on how to plumb the washer drain.

In theory, correct, and then there's murphy's law.

Because of the height of the drain plug, i believe you'll be obligated to a sink.

 

[jr7]

Ok so I may need to install a sink. If I were to do that would I then just put the washer drain in the sink and leave it? Now for the sink do i just remove the plug from the main drain and reduce it to 2" and add a p trap and connect it to sink? I'm getting some different options here but not much in the how to side. 1 person said just use an anti siphon, and 1 said add a sink? I may be more lost then when I started!

I might be corrected but I think you can install another why in the main stack a trap and a stand pipe 30 or 36" what ever code is. The machine can pump that high.

So when looking at the picture where do I put the wye and do I reduce in size to a 2"? How is this done? Thanks...

 

[nealtw]

You might just change out the "Y" for a double that has 2" on one side. You would like to have to remove more pipe and add that back to have room for the last joint made a rubber joiner.

[jr7]

So basically take out the "y" that it already has and replace it with a double "y" and 1 outlet in it needs to be 2" reconnect the existing plumbing and plumb in the trap and stand pipe? Can a trap be that high up? If I did it like that it seems it would be 3 feet off the ground or so? Am I in the same page as u r?

 

[nealtw]

You do understand I am not a plumber but yes you are on the same page. Your stand pipe will be up there but you said your machine will pump 96 inches or you could put the machine on one of those fancy drawer boxes.
Take your picture with you when you go shopping, if they can't help you sort it out try a different store.
