Washing machine plumbing? (1 Viewer)

[mooker82]

Our washer and dryer were previously in the kitchen. I installed french doors and am moving the washer and dryer to the new laundry area about 8 feet away in a closet. I have the hot and cold lines ran which are pex. My question is with the drain pipe and venting.

I planned to copy the p trap and standpipe dimensions exactly since I know they are up to code. The previous set up went from the p trap then dropped 90 degrees through the floor, exited out of the floor at a 45 degree angle, made a small run and straight into the drain line. There was no vent pipe exiting through the roof. This drain line is tied into the kitchen sink which is vented. Is this correct? Can I just run a new section of drain pipe straight into the line like it was previously?

It is in a straight line from the old set up but the pipe will be about 7 feet longer total. The drop will still be 1/4 per foot.

The setup looks like this minus the vent.

You'll need a vent for code and proper drain. Will it work without it. Most likely, but expect gurgling.

Is there any way you can tie the new vent, into the kitchen sink vent in the attic? You might just have to drill a hole in your roof and put down a flashing

We were able to get it done. Given the location a roof vent would not work. We used a Studor valve to vent. I know some people do not like them but it was the best option.

Those things have a tendency to fail...keep an eye for it.

If it fails, will more than likely get an overflow situation.
