Noob RODI plumbing question

I recently purchased an RODI system that I have been using on a slop sink with a hose adapter. Now that I'm starting to make a lot of water, I think I'd like to clean up the plumbing on it a bit. I've already figured out how I am going to plumb my waste water better (putting a Y in it with a couple ball valves, so I can either pump waste into a bucket for watering plants/hot tub, or run down the drain) but I have a question on the best way to plumb the input.

I want to put an adapter on that installs under the sink inline after the shut off valve on the cold water. I then want to run some of the tubing that came with the unit up closer to the RODI unit, and add another ball valve closer to the unit, so I don't have to get under the sink to turn it on and off.

Now, my (very Noob) question is: would the tubing be able to handle the pressure of always being connected to the watersource but turned off with a valve before it gets to my actual RODI filter? I don't know much about this, and I'd rather ask and look dumb then assume it'd work and have a flooded basement! :-[

 

I think it would be okay if the valve was a high quality valve, not one made of plastic but of metal or something. Im no expert but I think i would give it a try.

 

This is exactly how I have mine plumbed. I have a "tee" between the hard line and the flex line on my sink, Then it runs to a ball valve before the RO/DI. Works great. Shouldn't cause any problems for you.

 

Perfect! Thanks! =)

 

My valves are all John Guest plastic ball valves, a couple bucks at the hardware store. There is no need for heavy duty valves, it's only city water pressure.

 

Good to know, i have had any experience with using ball valves on my ro/di system so i wasnt sure. thanks

 

I should mention that john guest and murlock (both plastic quick connect fittings) are quality fittings, I wouldn't trust a dollar store valve (if there is such a thing lol).

 

Ya, I think I am going to be buying them from BRS and was planning on those two brands

 

You can get the valves and fittings you need in name brands at Lowes, Home Depot or any hardware store right on the shelf.
I would use a feed water adapter valve which installs next to the wall valve then as you say, run some tubing and place a valve closer to the unit.

Myself I used the cold water line that feeds my washing machine which is next to my laundry sink and installed a brass garden hose wye with built in ball valves, about $8 for a very good heavy duty one at HD or Lowes. The hose thread adapter then screws on to one side of that wye.

 

I didn't even think of that. It would be pretty easy to install something similar I think. I'll have to take a good look at it tonight and see what I can figure out. I think I already have everything I'd need to do that already!
