My washer & dryer is in the middle of my basement & I would like to move it to the other side of the house the only problem is it would be 14 feet from the main stack & vent.. Is this OK or what would I have to do to plumb it in (do I have to vent through the roof )

Thanks for your time
Rob

Hi Rob:

Easy enough to move the piping over but you will need to install an 1.5" vent within 3 to 5 feet of the 2" PTRAP and standpipe for the washing machine.

The new vent can run back and connect into the existing vent at the old washing machine.

Be sure to install a full size cleanout for the drain line.

Back to you...

Was the old washer drain vented?

[nortonalberta]

Thanks Mark that is very helpful.
Will I need to run 2" drain back to my 3" stack?

[nortonalberta]

Was the old washer drain vented?

Yes it is vented but is within 3' of the main stack

Has anyone mentioned mentioned installing a AAV?(see image) Check with your local Building Department to see if they're allowed. Good luck, Tom

Tom has given you another option for your vent. However, would recommend tieing into the existing vent if at all possible. As Mark suggested, take the vent off within five feet of the washer trap. Best to run two inch drain pipe to stack if possible and use 1 1/2 vent. Please let us know if this is all do-able. As it will make for an up to date, problem free install.

Dad and Mark are correct. I much prefer a natural vent to a mechanical one. If at all possible revent backto the old vent. To9m

Thanks all
I took a couple of pictures but can't figure out how to upload them... Thought it might be easier to explain with photos of my basement.
Thanks

Thanks speedball1... If this works you'll see 2 pics..
One is the washer & dryer close to stack & the other is where the washer & dryer is to go (where the drywall is leaning against the wall)14' away from stack

Hi Rob...

I'd cut a sanitary tee fitting into the pipe and run the piping over to the new washing machine. Install a 2" drain line with 1/4" pitch to the foot. Start your drain at lowest height possible and then pitch up from there. Hang the pipe every 4 feet to prevent any bellies from developing in the pipe over time.

At the corner where you make the change of direction with the drain pipe over to the washing machine you'll want to install a 2" long sweep elbow and a full size cleanout.

If allowed, as Tom pointed out, you could install a mechanical vent (called an AAV or air admittance valve) or you could install an 1.5" vent line and run it back to connect into the old vent as I mentioned. Either way works fine, except that the mechanical vent will save time and money!! You just need to be sure it is allowed in your area. If you pipe a vent be sure to pitch the vent so that if rain water gets into the pipe it will drain back to the waste pipe by gravity.

The standpipe from the Ptrap should be about 30" tall... see image. The image says between 18-36" standpipe....30" is ideal!

Thanks so much Mark the picture says a thousand words.Now can I run my vent along the wall just above the drain(back to the 3" main).I also forgot to mention that just below the floor joists I have a toilet,bath tub,bath sink,&kitchen sink draining into the main. If I cut into the main down low will I have any problems with gasses upstairs?

Thanks again

Rob

You can run the vent along the wall no problem... hanging it as you go at 1 hanger per 3 or four feet of pipe. Pitch the vent pipe so rain water that gets in the vent from the roof will drain away from the vent stack and toward the washer drain.

You mentioned the toilet sink and bath... we kind of figured that was what the big pipe was picking up... ;)

You will have no issues with plumbing above as long as you vent the washing machine as presented here.

Thanks again Mark.Please bare with me as I am not a plumber nor do I claim to be,it's just that we are doing a complete reno on our house & I am trying to do everything myself making sure everything is done right.
So from what I understand... pith a 2" drain line from the washer to the 3" main,, then pitch a 1 1/2" vent from stack back to the washer(so the pitch on the drain would be opposite the pitch on the vent??)Aslo in the first pic you can see a 3" pipe & a 1 1/2" pipe beside it....Would the 1 1/2" pipe be a dry vent? If so should I vent into the 1 1/2"?

Thanks Again

I bet Marks going to say "it works for me". Cheers, Tom

Thanks Tom
Do you think the 1 1/2" pipe to the left of the 3" stack in the first pic is a dry vent?I can see the 3" pipe come out my roof but no 1 1/2",would it ty into the 3" in the waall somewhere ?

Thanks

Hi Rob:

As Tom mentioned... you are all set with the piping as you drew it up.

In terms of the 1.5" vent pipe at the existing washer you can be sure that it connects into the 3" pipe at a minimum of 42-48" above the first floor. Here, the vent from the washer needs to connect above all the fixtures upstairs for it to be a vent for the washer in the basement.

When you connect into the existing vent be sure to invert your sanitary tee fitting so it is upside down... allows rain water to flow by gravity toward the washer drain. Turn a sanitary tee upsdie down... you'll see what I mean!

Your turn...

Ok thanks I understand.
I did forget to mention one more thing though... the drain for the washer is actually in the between the washer & dryer... Just to be clear should I vent into the 1 1/2" pipe?Also I have 2x4 frost wall,,can I run the drain & vent through the wall(typical 2x4 wall with concrete foundation wall behind)

Thanks
Rob

Hi Rob here again;
I don't know if I am over thinking things or simply not getting how this whole thing works.....I have attached another pic of the 1 1/2" vent( it's actually a 2" coming out of the concrete then reduced to 1 1/2 with a wye or sanitary T )The vent & stack seem to be done by the builder but somebody else roughed in a sink drain to the vent...Is this ok? I thought a dry vent was for venting only....then again why would there be a cleanout there.Seens how my washer drain is in the wall about 3' away i asume that the plumbing was run under the concrete into the main,so does the washer vent through the 3" as well as drain into the 3".

Very confused
Please help me understand

Thanks
Rob

I'm betting there is another drain and vent in the wall. Can you post a pic of the actuall washer drain after opening up the wall. This will tell us much.
