A water storage tank holds clean water from your reverse osmosis system until a demand for water is initiated in the house or business. Water is pumped into the tank from the water source, like a well or a reverse osmosis system. The tank accumulates water until it is full.
How does a pressure tank work?
Pressure tanks use compressed air to create water pressure within the tank. A pressure tank is constructed with an air chamber or bladder and comes with a pressure pre-charge. As the tank fills up with water, the weight of the water will begin to compress the air.
What is a well pressure tank?
Well pressure tanks also help maintain consistent water pressure throughout your house. These are hydropneumatic tanks, so, when you step into the shower you’re greeted with high-pressure water. The tanks air chamber compresses as water fills the storage tank and release pressurized water into your home when demanded.
How does reverse osmosis work?
Reverse osmosis storage tanks work on the same principle as well pressure tanks, but on a smaller scale. They are also hydropneumatic water storage tanks designed to provide pressurized water without the aid of a booster pump. They protect the reverse osmosis unit overall by ceasing water production when the tank capacity is full. Once the pressure tank’s psi reaches 2/3 of the water line pressure, the ASO valve will shut the system. This protects the RO membrane from being in constant use and prevents the system from perpetually sending wastewater to the drain. Reverse osmosis tanks are made of rolled steel, but internally lined with an inert material called butyl. This protects the purified water from making contact with any metallic surface.
