Familiarizing yourself with the functioning of your reverse osmosis system is important for its proper long-term operation and maintenance.
Among all the things you should pay attention to, you need to understand how your RO tank valve works.
Let’s find out!
Key Takeaways
First of all, how do you know if your RO tank valve is open or closed?
The valve of your RO tank should have a top that rotates 90 degrees to the left or right. The cap will usually have directional indicators for opening and closing the valve. So to check if the valve is open or closed, simply look at the indicators and see what way the cap is pointing.
In case there are no indicators:
During normal operation of your reverse osmosis system, your valve should always be open. The only case where you should close it is when you’re performing maintenance on the system. Even then, not all maintenance procedures require a closed tank valve.
The storage tank of your reverse osmosis system allows you to always have filtered water ready for dispensing without having to wait.
Mechanically, the tank is relatively simple. It’s a large chamber split into two parts. One part holds water, while the other holds air. The water part is connected to the RO system with an input and output valve. Once it starts filling up, this creates a pressure difference which then allows the water to be dispensed without the use of any pumps.
The valve of your storage tank is a simple mechanism for controlling its flow. Turning it switches it between an open and closed state, allowing you to temporarily shut off your system for maintenance.
