What do I need to install a reverse osmosis water purifier?
It is usually installed under the kitchen sink, preferably with an electrical outlet under the sink. A separate water source is not required, water is taken directly from the kitchen tap under the cold water pipe and the water pressure should ideally be around 2kg.
No less than 1 kg of flowing water pressure. The machine comes with a three-way ball valve as standard, so it is OK to connect it to the waste water drain, and it is OK to connect it to the downpipe.
How do I pump water from the water purifier?
The water purifier comes as standard with a special gooseneck tap, which is installed on the sink or counter top. Some kitchen mixers have a double tap with a dedicated 2-minute tap for purified water. The tap has a separate pure water switch, which is very convenient and eliminates the need for an additional tap for the water purifier.
What is the life span of the cartridge? How often is it replaced?
The cartridge in front of the RO membrane, also known as the pre-filter, is usually PP cotton cartridge and CTO and GAC cartridge and is recommended to be replaced once every six months.
The cartridge behind the RO membrane, also called the rear cartridge, is usually the rear activated carbon, commonly known as the T33 cartridge (or the large TT, generally the small TT, this cartridge is the smallest in volume in all cartridges) is recommended to be replaced once every 6-12 months.
We recommend that all cartridges are replaced once every six months, except for the RO membrane, in order to make it easier for you to remember.
RO membrane is recommended to be replaced once every 2-3 years. Different water quality, different water consumption, cartridge life and replacement cycle are different, the above values are for reference only.
Why is the PP cotton cartridge black when it has just been installed?
The activated carbon powder from the 2-stage cartridge will enter the 3-stage cartridge with the water, which is normal and can be ignored. The transparent filter bottle allows everyone to see this, the non-transparent bottle cannot be seen.
Why does the water start to come out black when the filter cartridge has just been replaced?
The carbon powder in the post-activated carbon cartridge will be rinsed out with the water, just rinse it out. When you buy a new machine, we test it with water before we ship it, and the black water is flushed out in advance, so it's not there.
Do all reverse osmosis water purifiers use electricity?
Most of them use electricity, very few do not. Those that use electricity are stable, those that don't are unstable and require high water pressure from the tap. Those that use electricity are mainstream, those that do not use electricity have a lot of waste water and are very wasteful of water.
Do all reverse osmosis water purifiers have waste water?
There must be, there has to be! A water purifier without waste water is not a reverse osmosis water purifier, this is determined by the basic principle, technology is more developed, reverse osmosis water purifier also has waste water.
As membrane technology advances, the proportion of waste water decreases and it is actually a simple matter to reduce waste water discharge by adjusting the waste water ratio (most machines are non-adjustable and can be replaced with a smaller flow rate waste water proportioner or waste water solenoid valve when the machine is manufactured).
But reducing the discharge of waste water comes at a cost: a. it reduces the quality of the water; b. it shortens the life of the RO membrane, which results in saving water but not money, and the RO membrane is the most expensive of all cartridges.
The same RO membrane, the same tap water, pure water and waste water ratio is 1:2.5 case, the removal rate is 96%, life is 3 years, the ratio is adjusted to 1:1 when the removal rate becomes 92%, life is less than 2 years.
In areas where the water quality is good, the wastewater discharge can be reduced and the life of the membrane is less affected.
