Feeding Multiple Outlets:
Feeding the filtered water to multiple outlets is doable. The key is choosing the right RO model that fits your
house’s water pressure level. This model should fill up the tank quickly and fully. A frequently full tank will then
provide good delivery pressure to feed the multiple outlets in your house.
We suggest limiting output points to no more than 3 outlets. Total tubing distance should be within 40 ft.
horizontal and 15 ft. vertical from the RO system (more or less).
Insufficient Water Pressure – Problems with Non-Pump RO Systems:
The 3 most common problems caused by low input water pressure:
1) Tank does not fill up, get little water from tank
2) Sluggish flow at the dispensing faucet
3) RO makes water slower than the claimed GPD
If you experience these problems, Please check your input water pressure as in section 9. This will often solve
the above listed problems.
How to Test Your Water Pressure:
Get a water pressure gauge that adapts onto your sink or garden faucet (from hardware store), attach gauge
onto faucet, turn water on to FULL, then take a reading.
For some areas, water pressure is lower during the day and higher at night when less people are using water.
So to get an accurate average, take several measurements at different times of the day and average them out.
Premature Membrane Failure:
There are 4 common causes that lead to premature membrane failure:
1. Failing to replace the 3 pre-filters as frequently as needed:
If you’re on city water
: The over-depleted carbon pre-filters allow the chlorine to get through and
damage the membrane.
If you’re on private well water
: The overloaded pre-filters allow excessive sediments and particles
to get through and clog up the membrane surface.
2. Your water source may contain certain organic or chemical compounds that form a slimy film which
covers up the membrane’s surface. This will disable the membrane prematurely. In this case, adding a
UV light could help extend the membrane’s life.
3. Your water source is extremely hard. This will clog up the membrane with heavy calcification. Adding a
water softener will help greatly.
4. If the drain water flow is somehow restricted or blocked, the membrane will be damaged prematurely.
So please check to make sure the drain water is draining off unhindered.
