I "make" my RO water in the basement in two Brute containers. I use this http://www.amazon.com/dp/B00SW32BUE along with a http://www.amazon.com/dp/B0001MII88 that is drinking water safe (not sure that really matters). I found an adapter for the pump to use the garden hose at Home Depot. I have a remote switch for the pump, so I can shut it off while I'm at the tank. I also have a valve at the tank end, as I prefer to slow the flow down while filling the tank. This setup works well for me, but I have been contemplating permanently running some pex tubing instead.
Whatever pump you get needs to have enough "head" to lift the water from your basement floor to over the edge of the aquarium, so read the specs of the pump. I wasn't sure about the internal parts of utility pumps and what metals might leach into the water (or oils), so I stuck with a fountain pump to be sure. But, I've read others using utility pumps and not having any issues. I'm sure I was being overly careful.
