RODI Hookup in garage

So I am moving into my very first house a week from tomorrow. That being said I have to move my 90g tank and 30g sump there too. I want to make sure I have some spare water on hand to top off the tank with as I won't be able to save all the water.

What is the best way to hookup an RODI unit in a garage? I currently have it setuo in my laundry room in my apartment via a y connector. However in my new house the w/d hookups are in the house and I would like to keep that stuff out of the way. Is there a cold water line i can "tap"?

 

Probably the feed to the hot water heater. You also want a drain for when you forget to turn it off

 

Well I have a auto shutoff valve on my unit so once my container is full, my float valve closes which creates backpressure which shuts off the unit.

Since this is my first house, I assume the hotwater heater will have marke in/out? Also how would I hook it to it? Is it a brass fitting to where I can literally put a tap on it?

 

There are a number of ways that hot water heaters are connected. I was lucky with mine in that it had a flexible supply hose to a shutoff valve that had a standard brass fitting on it. You can get the necessary hardware at most hardware stores in that scenario. Others have unions and still others are hard plumbed in (meaning you need to cut into the pipe to install the T). You're just going to to see what you've got and plan accordingly. Hopefully the unit has been replaced recently and has modern hardware on it that will make the job easy. Ideally it has a flex hose coming from the main supply to make fitting in an extra fitting a breeze.

 

You may also have a loop in the plumbing where a water softener is normally installed that you could tap into.

 

I have my RO/DI setup in my garage. I was able to tap into a spiget outside through my wall. I made it clean looking with a Washing Machine box installed in the wall. I ran a drain down the wall to the outside.

 

It wouldn't be my first choice, but if you have copper plumbing you can use a saddle valve. I think this is what your looking for when you say "tap into the line". The saddle valve clamps onto the copper pipe...when you screw it closed it pierces the pipe...when you screw it back open you have water...they are commonly used to hook up ice makers when a supply was not plumbed for them.
