I use old washing machine hookups for my
ro/
di unit. I've used BRS and currently running an aquatic life twist
ro/
di unit. It's as simple as just screwing an adapter onto the 'faucet'. You might want to get yourself a pressure gauge, as 90 psi is best for
ro/
di water creation, and a
TDS meter to go on your clean water to help gauge when its time to change out resin and filters. Both are cheap and easy to add on to any
ro/
di unit. If you're low on PSI, a booster pump is equally cheap and easy to install.
