 Washer drain to the toilet drain?

Subject: Can I hook up my washer drain to the toilet drain

Hi all! We have a house that has its washer drain into the bathtub drain. It has been working fine but when the washer spews out its used water, it comes out with so much force that it fills the bathtub a little through the drain hole.

We would like to fix this outflow issue while keeping the location of the washer and its inflow hookups the same. One thought is connecting the washer outflow to the toilet drain.

Could you please share your thoughts on doing this or another better solution? Thank you in advance!

Your plan does NOT show the washer discharging into the tub/shower branch drain.

Your plan shows it discharging into the 3" branch 'header' which is the proper way.

If actually piped as per plan you should NOT have an issue.

Thank you for your response! The plans were made before the washer was installed on the top/2nd level. Sorry I did not disclose that as they do not appear that accurate. In reality only has a single sink, toilet, and bathtub drain, which is also used by the washer currently.

Would it actually be possible and preferrable to drain it into the only vent stack of the home instead?
