Rate of water production depends on the model you buy (obviously), water temp, TDS in your tap water, and likely how new/old the filters are that are being used. I recommend going with no lower than a 75gpd unit. The price between the 75gpd unit and 50gpd is usually under 10 bucks....
On that note, the price difference between the 75 and 100gpd unit is also usually under 10 bucks. *Hint* *Hint*
Installation instructions will be included with most any unit. They have MANY ways to connect to every type of water line you would have in your house.

Do NOT buy a 100 GPD unit if it uses the popular Dow Filmtec membrane. Bad hint ! The 100 GPD is NOT a 98% efficient RO membrane but is in fact a 90% efficient nano filter intended for pool and spa use. The 100 GPD GE water membrane is a RO membrane but it takes 65 psi to produce that 100 GPD while a Dow Filmtec 75 GPD produces 75 GPD at 50 psi and the very same 100 GPD at 65 psi, its all in the way the advertise them.
The 8% difference in removal efficiency is a huge difference when you consider for every 2% you increase the membrane efficiency you double the life of your DI resin. Now figure out how much longer DI wil last with an 8% improvement!
A RO or RO/DI system can be portable, taking up about the same amout of room as two one gallon jugs of milk or water. You can hook it to a kitchen or bathroom faucet with an inexpensive adapter or to a hose bib type connector like a garden hose or washing machine.
They make water slowly, 75 gallons per day (3 gallons per hour) at 77 degree water temperature and 50 to 65 psi. You need to start out hours or days ahead depending on how much water you need to make so most of us use a storage container like a Rubbermaid Brute trashcan with a float valve installed so it shuts off when full.
