How much water does a Reverse Osmosis equipment discard?

Any Reverse Osmosis equipment throws water into the drain, since it is the main basis of an osmosis process. The reject/product ratio can vary from 2 to 1 (2 liters of water to the drain per 1 liter of good water produced) to 12 to 1, depending on the quality of the product, the working pressure and the characteristics of the water to be treated. Keep in mind that if the rejection is very small, then the reverse osmosis membrane saturates more quickly. In any case, the water we throw down the drain is not an economic cost, as we consume little water from the mouth (5 litres/day, we throw about 20 litres into the drain, 3 toilet cisterns). Per month it can be 1 m3. of water, which can cost €1.50. From an ecological point of view, I understand that the consumption of bottled water if the packaging is made of plastic (bottles or carafe) is more harmful to the environment.

What is the lifespan of a Reverse Osmosis membrane?

In quality equipment and well calibrated in its design, the life of the membrane is between 3 to 5 years. It is important to carry out regular maintenance, following the manufacturer's advice. Also important is the pre-filtration that the equipment incorporates: removal of suspended particles using sediment cartridges and chlorine removal using granular activated carbon cartridges or quality carbon blocks.

Water Jugs vs. Water Filters

The existing Water Jugs on the market incorporate a carbon filter along with other filter materials. Its main function is to eliminate chlorine, flavors and reduce heavy metals. A Bbagua filter (NATURAL-LIGHT, FILTER-FRESH, TAP FILTER) perform the same function as the Water Jug, but in a more user-friendly and more economical way: the duration of our cartridges is between 6 to 12 months, compared to 2 months for jugs. Jug cartridge costs range from:

My product isn't working. What to do?
  1. First of all, check:
    1. That the installation has been correct, following the instructions.
    2. That there are no water leaks in the system circuit.
    3. That electricity arrives (if the product requires it), that water reaches the product. Check that the stopcocks are open.
    4. That the water pressure is what the product requires. See instructions.
  2. If, after checking the above, the problem has not been solved, before RETURNING the product to your purchasing centre, contact the Technical Service Bbagua through the website or by phone 93 783 33 92.

No water coming out of the tap

When the equipment is new, the tank filling time is around 3-4 hours. If the problem persists, please take into account :

  1. Have your pipes well connected.
  2. That you have not tampered with the accumulator tank.
  3. That it has the right pressure.
The water in my Reverse Osmosis equipment comes out cloudy, what do I do?

If after performing 2 to 3 flushes, the problem persists, perform these operations:

  1. Empty 3 more reservoirs.
  2. Fill a glass and let it sit for 3 hours and if at the end of this time, it has disappeared, it was air.
My Reverse Osmosis equipment hasn't improved my water, it still tastes bad.

If you have this problem, do the following:

  1. Check the correct placement of the membrane, following the instructions.
  2. Check that the pipes are connected where they touch.
  3. Make sure the inlet pressure to the equipment is correct.
My water softener isn't working, what do I do?

Perform these operations before calling  the SAT:

  1. Make sure you have the meter cable and the By Pass keys plugged into place.
  2. Make sure you have the necessary salt for your wash cycle.
