Reverse Osmosis System Startup

Congratulations on you new Reverse Osmosis Water System from Think Pure Water.

RO systems produce some of the purest water in the world. The least amount of water is wasted when you use the whole tank full and let it fill again from empty. Its best to simply fill water jugs and leave them in the fridge or on the counter. Taking a glass from a full tank wastes the most water.

Empty your RO tank every month. Here is why. RO membranes are generally self cleaning as waste water clears away most hardness minerals and impurities. When the tank is empty, there is no back pressure on the membrane and this allows the most effective flushing of the impurities. Taking a glass of water from a full tank never allows the membrane to clear itself. Simply emptying the tank every month greatly increases the life of the membrane.

STARTING UP your newly installed system. All RO systems produce water slowly and also produce reject water in the process. Therefore, a storage tank is necessary so plenty of pure water is always available. The first TWO full tanks MUST be discarded into the drain to clear the system of disinfectant crystals in the tank. (These are not toxic but won’t taste good)

STEP 1. When first installed, allow the 2.5 gallon tank to fill completely ….. about 1 to 2 hours. If you listen closely to the disposal drain in the sink, you can often, but not always, hear the reject water passing thru there. When the noise stops, the tank is full. You can also lift the tank to feel if it is full.
STEP 2. Open the new RO faucet and drain the tank to empty ….. about 4 to 6 minutes. A small dribble means the tank is empty. This is the new RO water being made but won’t fill the tank unless you shut off the faucet.
STEP 3. SHUT OFF THE FAUCET ….. so the tank can refill. If you don’t, the water that’s supposed to fill the tank will dribble out the faucet continuously.
STEP 4. Let the tank fill again ….. about 1 to 2 hours.
STEP 5. Open the new RO faucet and drain the tank to empty ….. about 4 to 6 minutes.
STEP 6. SHUT OFF THE FAUCET AGAIN and let the tank fill ….. about 1 to 2 hours.

This 3rd tank is now ready to enjoy.
