I'm going to redo my laundry area in the basement. I have a good washer and dryer I'm going to stack. Right now they're sitting on either side of a horrid plastic utility sink that, any time to bump it, shakes the copper supply lines. So I plan to get a new laundry sink and plumb it in with some pex.

Does anyone have any good ideas on a nice looking way to setup the pluming for the washing machine? I like the outlet boxes you can get, but these are made for being in a wall. I only have a concrete wall behind the washer. I'd also like to drain the washer in a better way than dumping it in the sink.

Are there any good ways examples of nice unfinished basement approaches to organizing the washing machine plumbing?

Thanks

Bernabeu, what is the reason to revent the washing machine drain? I thought in this case both are stack vented and with modern day low water consumption machine bring standard why would a revent be necessary unless the distance along that arm exceeds the max 8' for a 2" pipe at 1/4" per foot?

sum, there is another fixture draining into that 2 inch stack.
it is entering the stack above the washing machine so there has to be a vent for the lower fixture.

+ regardless of MINIMUM code allowances INDIVIDUAL FIXTURE VENTS are good, if not best, practice +

+++++ low water consumption maybe, BUT, extremely high discharge GPM (rate) +++++


labor for a DIYer is a non issue, so a few bucks for some extra pipe and fittings

I like to see the vent there but it's not really needed ( as long as the two branches are within 10" of each other).Another thing I (and most inspectors)like to see now is right up to and including the stand pipe full size 2".Like bernabeu said....the new machines dump everything they have in a few short seconds.

Hi bernabeu,

Thanks for the photos. Below are some photos of the sad situation I'd like to remedy.

A couple of questions: Where should the vent lead? I'm not too eager to cut into my main drain/vent going upstairs. Also, how about arresting water hammer. I thought about putting one on either supply before splitting them to the sink and washer.

You are currently unvented.

OP,

Based on the (new) photos:

You presently have an UNVENTED 'S' trap.

Your only 'practical solution' is to install an Automatic Air Vent (Studor vent) at the top of the 'down pipe'.

else; a serious plumbing project involving walls and stacks

You probably should merely upgrade the existing utility sink to a 'prettier' one as the HE washer almost requires the 'drain reservoir'.

There are 'drop in' utility sinks for installation into a cabinet of your choice (similar installation to a kitchen sink), resulting in a 'vanity look'.




AFTERTHOUGHT: Juuuuust maaaybe (if you have an older home on a hill) the washer drain goes to a 'drywell' since it is merely 'greywater' - just AAV the drain and use a cabinet
