Hi sunnyspony
I bought a Kent unit a month or so back.
Mine came with a hose adaptor for a regular garden hose, which didn't help me much.
You can install it a few different ways.
1) Order the saddle valve, small brass wet tap valve like you use on an ice maker behind your fridge. This is for a permanent installation.
2) Kent offers a faucet fitting that you can screw onto a standard kitchen or bathroom sink, first have to remove the screen and end fitting you have on them now. You can still use the faucet, and just hook up the RO unit to the barbed fitting sticking out the side when you want to make RO water. This is more of a temporary installation.
3) The garden hose adaptor is still an option too.
I got a 12 gallon plastic container to keep water RO water in. I run the unit on one of my days off, fill'er up and it lasts me a week with 4 tanks to top off.
Hope this helps out !
