Rodi setup - using washing machine line

Anyone use something like this to supply water to their rodi unit?

Brass 2-Way Restricted-Flow Water Shut-Off https://www.lowes.com/pd/Brass-2-Way...t-Off/50328303

Thinking of using something like this but worried if the washing machine which will be connected to one side will suffer restricted flow due to the restricted opening.

Should be fine. The rodi isn't pulling that much water from it, if they happen to be running simultaneously.

If anything the washing machine will probably draw from the rodi when it's on.

The restricted flow is being able to control both sides independently. Without having to shut the water completely off....not necessarily less water.

Thanks for the reply.

Not really worried about them running simultaneously but more so on whether the washing machine will be affected by not getting the pressure of water it needs through that small opening.

I’ve seen some people on YouTube using these connectors but not 100% sold.

-when the washing machine is filling you likely won’t have enough/prober psi through anything above i’d guess 60 gpd membrane.

-the washing machine doesn’t pull water, and many rodi units have one way/back flow/check valves on them

- the split hose valve pictured is notorious for cheap construction and not completely closing

-better off with a tee and two separate valves

That makes sense.

I guess a standard Y connector with a single, better shut off valve on the RODI side will work.

Which? The Y connector with the two diverter valves?

Exactly what i said..while the washing machine is filling, most of the water and pressure coming out of the spigot will be utilized by the washers greater demand.

I wasnt saying the washer will "pull" the water from the RODI literally....i mean it will rob the water pressure from the RODI, much like when someone flushes the toilet and the shower pressure drops.

But for how many hours a day do you fill your washer?? I still think it will be fine.

As for the construction of the valve itself..im sure it is cheap. Probably cheap plastic 1/4 turn ball valves inside.
