Get an Ro
unit. You'll thank yourself later.
I ended up getting the 6 stage unit from filterdirect on ebay. The unit is awesome!! Gives me 100% pure water and is decently fast. You can ask them for the in-line cold water connector for no extra charge. I would also recommend getting and installing a float valve so that way you'll never risk overflowing your container bucket. Runs about $16. The entire setup, plus float valve and water TDS
meter, with shipping was under $150. A steal if you ask me!
You can just stick it under the counter. Keep an extra bigger bucket for the waste water since you can't install perm.
