Product Questions

Hey guys,

Adding some upgrades to my 4-stage Plus RO/DI. I want to split my product line to two separate locations. If I do the split after the check valve (included in the *Plus system) would I need to add any more of these? Maybe one for redundancy?

Thanks!
Randy

Hey Randy,
Sorry but the image doesn't seem to want to cooperate. That said though, no extra check valves should be necessary as long as its split after the check valve . The included check valve on our units is in the membrane housing so you couldn't split before it if you tried. As far as running to multiple locations, its as simple as a tee. I would recommend adding an inline ball valve to each side of the tee so that you can manually control which one is filling if you desire (otherwise it will just favor the path of least resistance). Another option would be to use a 3 way valve, though personally I prefer the two single inline valves as not only is it a bit cheaper last time I checked but you also have the option to leave both open, so in theory it would fill the first container, when the float goes up be forced to go the second container, and when that float goes up be done. With the 3 way ball valve you would have to manually switch from one container to the next. Just my two cents worth :-)

Will this work for CO2 line for Calcium RX.
Question by: John H on Jun 14, 2016, 5:34 PM
This will work perfectly with the Vertex Calcium. Feel free to let us know if you have any further questions!

would this work on 1/4 inch airline tubing?
Question by: Matt on Aug 24, 2015, 1:30 AM
Great question!
You will need to use a Mur-Lok Stem Adapter to convert the Murlok fitting to a barb where the airline could slide over. I have attached a link below.

Would this work on an ATO line to prevent it from siphoning into the sump? I tried a generic check valve for RO system, but it requires too much PSI to work.
Question by: Lon Varscsak on Nov 25, 2021, 4:23 AM
Yes, this will work, the biggest challenge will be connecting your soft tubing as it is meant for rigid RO tubing.
Answer by: Matt Lucero (BRS Staff) on Nov 27, 2021, 6:29 PM
If the output connection on the RO housing is the Mur-lok Elbow Check Valve (your product SKU: 200801), then this inline check valve would not be necessary to allow for the auto-shutoff valve (your product SKU: 200011) to function correctly, yes?
Question by: Joshua Nelson on May 3, 2016, 5:12 PM
Correct,
The check valve is already built into our units and this separate check valve is not required for our auto shut offs to work on our units.
