3 Things of Purchasing an RO System  

Water Source

The Reverse Osmosis System is fed with water that has been delivered to your property. Inorganic dissolved solids may be found in city or municipal water, which is free of chemicals and germs. Fortunately, RO systems are designed to remove such particles. On the other side, private well water may include harmful pathogens and chemicals as well as dissolved solids.

Reverse osmosis systems are only effective in removing pollutants from city and well water if the water has been previously treated.The membrane should be cleaned in order to prevent it from becoming clogged with bacteria and particles.You’ll need a UV system to disinfect the water after it leaves the storage tank if your well water has serious metal pollutants like arsenic.

Water Demand

It’s essential to think about how much water you and your family consume. According to nutritionists, the ideal daily water intake should be half a person’s weight in ounces. You should drink 80 ounces of water every day if you weigh 160 pounds. When calculating your water usage, you should take into account ice machines, refrigerators, and other appliances. A reverse osmosis system produces the amount of water consumed daily in GPD (gallons per day)

Water Pressure

With water pressure, reverse osmosis can force water through its membrane. Increasing the water pressure for reverse osmosis is required when the house water pressure is below 40 psi. You can use an RO booster pump for this. Also, make sure the tanks’ water pressure is adequate for the RO system to operate if you utilize a well water supply. When the pressure within the RO system is too low, water containing a high degree of dissolved solids can also raise the bar.

Additionally, point-of-use residential reverse osmosis systems are more convenient since you may put them where you need the filtered water. You can directly install most RO Systems under your sink. Because Whole house reverse osmosis systems require a large storage tank and booster pump before getting adequate pressure to deliver water to every point of your house, they are used less often.

Plumbing Requirements

Before purchasing a reverse osmosis system, it is critical to think about a few plumbing things. The first step is to check out the space under your kitchen sink; a reverse osmosis system takes up a lot of space due to its multiple filters and large storage tank. Therefore, items stored under your sink have to go. Fitting the reverse osmosis system beneath the sink will be difficult if you have a garbage disposal.

Tank Size

RO tanks have sizes between 3 and 14 gallons. Nonetheless, the capacity of a reverse osmosis system tank may be deceptive.  Usually, the tank capacity is less than that stated on the label since RO storage tanks have a metal bladder and a bubble of air that supplies enough force to push water through the faucet when the tap is opened.For example, a 4.5-gallon tank can contain roughly 2 to 3 gallons of water. It is critical to consider tank sizes while purchasing a RO tank system, especially if you have a large family and require more water on a daily basis.


The wastewater creation issue with the reverse osmosis water filtering technology is a major disadvantage. Standard water filters remove solid contaminants when water passes through the filter. RO systems, on the other hand, remove pollutants in liquid form as wastewater, commonly known as brine. Conventional RO systems create a substantial quantity of brine, around 3 to 25 gallons per gallon of clean water, so only purchase ones with low wastewater to pure water ratios.
