Moving laundry to the basement

I need some help with my newest project. I want to move my laundry room from main floor to the basement (need to make the bathroom larger). The house used to be on a septic tank, but has been converted to city sewer. The main drain pipes go out the basement wall instead of the floor. The pipes are 3" and the center of the pipe is 57" off the unfinished basement floor. I will be building walls around this, but will not finish this room. My question is - how can I hook up the drain pipe? Will I need to build a platform to raise the washer? Any help is greatly appreciated!

Just following the thread good luck. I'm looking at doing a similar project.


If I could only remember to THINK about what I was doing before I did it.

The mouth of the washing machine drain riser has to be at least 18 inches above where its trap ties into the house drain line and (not relevant here) above the level where water would overflow out of the washer itself if the water got stuck on. It's a minimum of 2 inches in diameter so I think that makes the mouth 19 inches above the center of the drain pipe. So 57 plus 19 is 76 inches above the floor.

The existing washing machine drain hose must be able to reach it and fit down in loosely. No splicing on an extension hose.

A platform for the washing machine is possible.

If this is too high, you will have to install a sewage holding tank and pump.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

I wouldn't suggest trying to elevate the washing machine. Use a pump system instead as AllanJ mentioned. Something like the Liberty 404

If you plan to eventually put additional fixtures, i.e. a toilet, etc. in the basement then you'll need a larger pump and basin installed under the slab. Something like this:
