RO system setup on washer/dryer line

[DOJOLOACH]

So, does anyone have bad experiences with hooking up their RO through the washer and dryer connections?

I ask because im moving to a brand new 3rd floor apartment and dont want excessivebackpressure on my internal piping and cause a burst. 

 

Ive had a faucet hose break on mebecause of this

I have a spiltter directly off of the cold spigot. One side to the washer , other to the rodi. Have ran that setup for 10 years with zero issues.

Excellent. I was originally planning to buy a manifold of sorts but your idea is better since i only need cold water anyways

That's how I do it. Bonus is you can ran the waste into the washer and wash your clothes. Saves water.

!!! Thanks Jrill I hadn't thought of that either. Maybe my clothes will be softer now too lol

I have done the same without any issues. Make sure you have adequate water pressure otherwise a booster pump may be worthwhile!

I have mine on washer's cold water and waste doing down the drain.  So far no problems

@Jrill how do you make sure not to flood your laundry room, will the washer cutoff water flow at any point?

@DOJOLOACH you will want a float valve of some kind to shut off your RO system flow when your water storage container gets full, otherwise you'll just have to keep a close watch on it, and that's when most RO floods happen, we just forget to turn it off manually. As for the wastewater line, you can put it in the same drain that your washing machine uses, so there's no worry there. If the washing machine is running at the same time as you are filtering water, it will reduce the water pressure going to the RO membrane when the machine is drawing water, and reduce the RO output a tiny bit in that moment, but there's really no need to worry.

I set a timer. I also see approximately a 3 to 1 ration of waste to ro.  The bucket my ro goes into is 5 gallons with a float switch and my washer holds 15 gallons at the high level.  But still I set a timer just to make sure.

You may have missed it but we're talking about saving the waste water into the machine to use it instead of wasting it.
