The Benefits of Using a Pressurized Storage Tank for Your Reverse Osmosis System
Introduction
When it comes to reverse osmosis (RO) systems, having a pressurized storage tank is essential. In this article, we will discuss the importance of a pressurized storage tank for a reverse osmosis system and how it works. We will also address common misconceptions about the tank's capacity and provide a step-by-step guide on how to properly pressurize a reverse osmosis tank.
What is a pressurized storage tank?
A pressurized storage tank is a crucial component of a reverse osmosis system. It is designed to store and provide a steady stream of Water on-demand. The tank is completely encapsulated on the inside and features a pressurized air bladder. It is coated with a food-grade polypropylene and butyl treatment to ensure the water's purity.
Why is a pressurized storage tank necessary for a reverse osmosis system?
Reverse osmosis systems tend to have a slower water production rate. The pressurized storage tank compensates for this by providing immediate pressure to the RO faucet. This ensures that when You turn on the faucet, you have a continuous flow of water without the need to wait for the pressure to build up.
How does a pressurized storage tank work?
The pressurized storage tank operates by utilizing the pressure from the bladder and air inside the tank. As the tank fills with water, the bladder fills with air, allowing the tank to store water under pressure. It is important to note that the tank's capacity is affected by the presence of the bladder and air inside, resulting in a lower actual water holding capacity than the maximum stated capacity.
Tank capacity and misconceptions
One common misconception about pressurized storage tanks is the belief that they can hold the full stated capacity of water. In reality, due to the presence of the bladder and air, the tank will only hold a portion of that capacity. For example, a four-gallon storage tank may only hold around two and a half gallons of actual water.
Importance of pressurizing the reverse osmosis tank
Pressurizing your reverse osmosis storage tank is vital for maintaining the performance and water flow of your system. If the tank is not properly pressurized, you may experience issues such as low water pressure, reduced water volume, and slow flow from the faucet.
Issues with an improperly pressurized tank
If you Notice any of the aforementioned issues, the first step is to test the tank to determine if it is full of water. You can do this by lifting the tank and assessing its weight. If it feels heavy or if you can hear water moving inside, it is likely that pressurizing the tank is the problem. On the other HAND, if the tank feels light or empty, the issue may be with the filters or membrane that need replacement.
Steps to pressurize a reverse osmosis tank
To pressurize a reverse osmosis tank, follow these steps:
- Turn off the water supply to the system using the cold water feed valve.
- Turn on the RO faucet to empty the pressure tank. Initially, there will be a strong flow, but it will reduce to a Trickle once the tank is empty.
- Keep the faucet on trickle mode while checking the pressure and pressurizing the storage tank.
- Check the pressure of the tank when empty. The internal bladder should have a minimum pressure of 7 psi and a maximum of 10 psi.
- Use a low-pressure gauge to check the tank's pressure. Avoid using car tire pressure gauges as they may not accurately measure the tank's pressure.
- If the pressure is below 7 psi, add air pressure to the tank using a bicycle Pump or hand pump.
- If the pressure is above 10 psi, release some air pressure from the tank using a sharp object, such as a pen, to depress the valve stem.
- Once the recommended pressure is achieved, shut off the reverse osmosis tap and turn the water supply back on to the pressurized storage tank.
- The tank will refill within one to two hours, depending on the water pressure and whether a booster pump is present.
Checking the air pressure of the storage tank
To check the air pressure of the storage tank, remove the cap covering the valve stem or pressure valve. Use a low-pressure gauge to measure the pressure. Ensure that the pressure falls within the range of 7 to 10 psi. Regularly check the tank's pressure to maintain optimal performance.
Maintaining the pressure of the tank
To maintain the pressure of the tank, periodically check the tank's pressure and adjust it if needed. If the pressure falls below 7 psi, add air pressure to the tank. If the pressure exceeds 10 psi, release some air pressure. Regular maintenance of the tank will ensure its optimal functionality and longevity.
Conclusion
A pressurized storage tank is a vital component of a reverse osmosis system, providing the necessary pressure for a steady flow of water. Ensuring the tank is properly pressurized maximizes the system's performance and prevents issues such as low water pressure. By following the steps outlined in this article, you can maintain the pressure of your reverse osmosis tank and enjoy clean and refreshing drinking water. Remember to regularly check the tank's pressure and address any issues promptly for optimal results.
