Front-loading Washer Drain


I want to move my front loading washing machine, but have a question about the drain. The manual says to drain it into a standing drain pipe. However, can that pipe then run horizontally with 1/4" or 1/8" slope to connect to the main drain? Or will the pressure cause the water to backup? I'm not sure how hard a front-load washer pumps the waste water. Perhaps if I put in a 4" drain, it won't matter? Any thoughts?

Thanks!
Chris

Washer drains are to be vertical. They also require a trap. Newer codes are requiring 2" drains instead of the traditional 1-1/2" since newer washers have faster and more powerful pumps. Aside from any Code violation, I think this would cause you problems with drainage.

Do you mean that washer drains have to run directly into a main stack? (With the trap in place, of course.) Looks like I may be breaking out the jackhammer

Not saying "directly" into the main stack, just that they require a trap, the same as any other fixture.

So can I put in a vertical standing pipe, with a trap, and then from the trap run a horizontal pipe with 1/4" per lin foot of slope to my main stack? I'd have to cover about 10' of distance. Or would this be a code violation?

Not sure what your local codes are, but it would work where I have worked and lived.

That would really be a violation. Using 2" pipe from a trap can only run horv for eight feet.


Max distance from a trap on a horz run

1 1/4 = 5 ft
1 1/2 = 6 ft
2 = 8 ft

That is uniform plumbing code 2006

Plumber101, thanks for the input. This is why I stated about local codes.

It should also be vented.

Are you saying that the horizontal can only run a total of 8 feet or that 8 feet is the maximum trap to vent distance? Just curious. Where I'm from, you can run the horizontal as far as you need to as long as a vent is within 8' (for 2") of your trap.

With more than 8 feet horizontal distance, the water won't flow fast enough down the drain pipe for the gallons per minute output from the washing machine, even with venting.

There are probably some figures for fatter drain pipes or greater slope for the "horizontal" run allowing for a greater distance from the machine to the main drain, although I don't know what they are.

Thanks for all the help -- after some consideration, we're going to enlarge the basement bathroom, and put the washer/dryer in there as well...Simplifies the plumbing issue!

And that just ain't true...

The reason you can not run a horz drain from a traped fixture more than eight feet to a vent or verticle drain is the water in the trap weir could be removed leaving a void in the trap so that sewer gas can escape.

Now your statement could be true if the main drain is not sized correctly for the total nimber of DFU's to drain into the 2" pipe
