Team MARSH,

I'm installing a new RO/DI system and would like to route the wastewater into a washing machine wall drain in an adjacent utility room. I plan to remove/repair/replace sheetrock as needed...:oops:

Does anyone have knowledge of specialized fittings or other ideas that would help make my installation neat, tidy, and Wife-approved?!?

Thanks in advance for sharing your installation examples and/or thoughts.:unsure:

Happy reefing,
RobbyeD

Try one of these, and then drop the tubbing into the washing machine drain.

I couldn't imagine why you were messing with sheetrock, then I re-read and see you are in an adjacent room to the laundry room.
I think I'd use an outlet gang box and select a switch cover that was just large enough, then mount it at the same height as your outlets on the display side wall, and snake it up the cavity to the drain box. In my mind, no matter what you use, it will look like a tube in the wall, but if it is consistent with other wall penetrations / outlets, then it can blend in.

I just shoved mine into the drain and zip tied the ro/di to the washer hose.

At my old place I ran it outside to water the back yard's grass which was nice. The hose connectors would break at times, but at least the water was being used.
Literally the same as what I did. My unit is in the garage mounted on the wall and the other side of the wall is the laundry room. I drilled holes in the drywall and ran tubing through the wall.

During the summer months I have a very long tube that connects to the waste water part of the unit and I run it out to my yard to water the grass.

That's exactly what I do with mine. Shove it in and zip tie to the washer cold water line. ;)

Right now....I'm looking for a good PVC or ABS 2-way water splitter valve for the cold water line. I need one on my new build. The last build I used a high quality brass splitter, but I got thinking....that's probably not a good idea...no telling what might try to sneak past my filters.

Pic heavy....sorry.

My last one was like this....I wonder if it would create issues down the road?

I’ve been using a brass one for maybe seven years now. Never had an issue.

Me either. I just ordered another one. It's solid brass. 5,000 good reviews. Very good O-rings.

I found a pretty decent 2-way splitter on Amazon:

I know you said you chose brass. IMO its no big deal. The majority of homes built - PRE - Pex (mine included) use copper for water lines so.....

Use blank outlet plates, drill holes, and mount quick connect bulkheads. That allows you to easily switch around tubing if you’d like. Here’s the one I use going into my laundry room from the garage. I just fed the tubing and didn’t use the quick connect, but the idea is the same and it looks much cleaner. Plus, you can just make a larger hole behind it to make routing tubes better while the face plate looks cleaner.

We mounted our rodi in a small utility closet in our laundry room. We drilled a hole through the drywall and into some storage cupboards above our w/d connections and dropped the lines down behind a wall mount we made using distressed wood. We tapped into the supply line to feed the rodi and used the same route to then feed the waste line right into our washing machine waste line. In the Spring/Summer we do a quick connect to the rodi waste line and capture the water for use in watering the garden and washing the vehicles.

Suggest you change the configuration of your system so that you don't have horizontal DI stages. They should be mounted vertically, with bottom-> up flow through each. They should be packed tightly so there is no free/empty space in the cartridge.
