A reverse osmosis auto shut off valve is used to stop the flow of water through an RO system when either the pressure or flow rate reaches a predetermined level. This prevents waste of water and helps ensure that the system does not become damaged.
How does a reverse osmosis water shut off valve work?
How Reverse Osmosis Shutoff Valves Work. The two halves of the valve are separated by a piston, which keeps the permeate water on one side and the incoming tap water on the other. As long as the pressure on the tank side is less than 2/3 the pressure on the tap water side, the piston remains open and the unit continues to produce water.
What is an automatic shut-off valve?
An automatic shut-off valve is a component integrated into the water distribution system of a home. Its main purpose is to keep track of the water pressure in the plumbing system. If the valve detects an imbalance in the pressure, it will be interpreted as a problem. Should this happen, the valve will automatically cut the flow of the water off.
How do I install an auto shut off valve?
Follow these instructions to install an auto shut off valve on your RO system. First note the top and bottom of the shut off valve, the bottom has screws and the top has in/out marks. The red line exits from the last carbon block, enters the "in" on the top of the valve, exits through the "out" on the top of the valve and enters the RO membrane.
Which side of the Ro valve does the product water enter?
When the "permeate" water (the product water of the RO unit) leaves the other end of the membrane housing, it flows to one of the "tank" ports on the other side of the shutoff valve. It doesn't matter which port it enters, since the "tank" ports are interchangeable and water flows either way on this side of the valve.

How does a automatic shutoff valve work?
An automatic water shut-off valve detects water either by monitoring flows in the pipe or by detecting water on the floor. When flow is irregular or moisture is detected, the valve will shut off the water supply to your home. These can prevent a significant amount of the damage that water leaks cause.

Should RO system constantly draining?
The reverse osmosis system shuts down when tank pressure reaches 2/3 of supply line pressure and the ASO valve closes. Constant water running to the drain simply means that the ASO is not shutting off. The ASO operates if the membrane, flow restrictor, tank, and check valve are all performing properly.
Where is check valve on reverse osmosis?
Every reverse osmosis unit has a one-way valve called a check valve in the “permeate” line as it leaves the RO membrane housing. This is usually a small, inexpensive part, but it is essential to the function of the unit.
What is solenoid valve in RO?
The Solenoid Valve in the RO Unit is an Electro Mechanical Valve. This allows the Raw Water to Enter in to RO Unit when it is Only Energized with a Power Supply. When the Power Supply is Cut-Off, this Valve will not allow to flow the water. ( Normally Closed. Sales Package.
Why does reverse osmosis drain water?
A traditional reverse osmosis filtration system uses more water than it produces of RO water. To produce a gallon of purified water, multiple other gallons of water are sent down the drain as reverse osmosis waste water. This is just a fact of the purification process.

What happens if RO tank pressure is too high?
If tank pressure is too high, then water coming from the filters won't enter the RO holding tank. The ideal tank pressure is 8 psi. You can attempt to re-pressurize your RO tank with a bicycle pump, but be sure to drain all of the water in the tank first. Be aware that RO pressure tanks wear out with time.
How long should an RO system drain?
Since the Reverse Osmosis drinking water system (RO) flushes it's waste water while it is filling the tank, water running to drain during production is normal but after 3 or 4 hours of zero water usage there should be zero water running to the drain.
How much pressure should a RO tank have when full?
30-40 psiIn an empty tank, air pressure should be 7-10 psi. In a full/heavy tank, air pressure should be 30-40 psi. To be accurate, air pressure should be 2/3 of incoming water pressure. When the tank is full, and if feed water pressure to the RO system is 60 psi, then a full tank should have 40 psi.
How do I stop my reverse osmosis gurgling?
If the reverse osmosis system's flow control allows too much water to flow, it can create a constant gurgling flow of water through the P-trap. To repair this problem, replace the reverse osmosis system's flow control valve.
Can I use reverse osmosis system without tank?
The storage tank is required because RO is an inefficient process. Even with adequate water pressure feeding the system, the flow rate of filtering water is much slower than that of tap water directly from the plumbing.

How does a flowmatic shut off valve work?
In other words, tap water enters the lower right and flows out the upper right toward the membrane, while the lower left and the upper left ports handle the permeate to tank water.
Where is the check valve in a shut off system?
It is important to know that in order for the shutoff system to work, a check valve (one-way valve) must me installed in the permeate tube between the membrane and the shutoff valve. Without the check valve to contain the back pressure from the tank, the shutoff valve cannot function.
How does reverse osmosis work?
Modern undersink reverse osmosis units use a simple but effective shutoff device to turn off water production when the unit's storage tank is full. The shutoff system monitors the pressure in the storage tank and shuts off water coming into the RO membrane when tank pressure reaches approximately 2/3 of the pressure of the incoming tap water.
Where is the Payne shut off valve?
The Payne shutoff valve is clipped to the membrane housing of the unit above. The tubes on the right side carry tap water to the membrane. On the left, or "tank" side, permeate water leaves the membrane, passes through the cigar-shaped check valve, and enters one of the shutoff valve's "tank" ports. It leaves via the other tank port and flows to the tee, which sends it to the storage tank.
Where does water go in a RO unit?
1. After water leaves the RO unit's prefilter, it enters the "In" port of the shutoff valve, lower right in the picture. It then makes a horseshoe turn and exits the "Out" port, lower left in the picture, through which it flows to the inlet side of the RO membrane.
What is an auto shut off valve?
The auto shut-off valve and flow restrictor combination regulates the flow and use of water in the RO system, serving three very important functions - it holds the water in the RO membrane so that it is purified fully, it reduces water waste, and it prolongs system life. Due to our advanced flow restriction configuration only 4-5 gallons of brine water are made per gallon of drinking water depending on water conditions and pressure, compared to the common 8-9 gallons of brine water produced per gallon of drinking water on competitors' RO systems. The automatic shutoff consists of 2 diaphragms and a plunger. The plunger moves up or down in the housing based upon pressure differential between the incoming water pressure, and the back pressure from the reserve tank.
How does the lower diaphragm work?
The lower diaphragm pushes the plunger up allowing feed water to flow through the inlet/outlet port until the storage area pressure exceeds one half the inlet pressure . At this point, the storage area pressure on the upper diaphragm is great enough to push the plunger down stopping the flow of feed water. Flow will not start again until the storage area pressure drops because of water withdrawal at the faucet.
Do you need an automatic shut off valve for a permeate pump?
Home Master Systems with the permeate pump upgrade do not require an automatic shut off valve, as the permeate pump will function in this capacity.
How to install a shut off valve?

The "in" and "out" portions are interchangeable for the blue line.
Where does the red line exit from?
The red line exits from the last carbon block, enters the "in" on the top of the valve, exits through the "out" on the top of the valve and enters the RO membrane.
Does RO have a check valve?
Many RO systems come with the check valve built in, check to see if yours has one. It will be inside the 90 degree hose fitting (pictured above) or may be an inline check valve (pictured right). If your system doesn't have one, both types can be purchased for a few dollars.

What Is the Purpose of an Auto Shut Off Valve on a Reverse Osmosis System?
The purpose of an auto shut off valve is to prevent the reverse osmosis system from running without any water. The valve will detect when the flow rate has dropped below a certain level and will automatically turn off the system, preventing it from running dry or damaging the equipment. When using an auto shut off valve on a reverse osmosis system, it is important to ensure that the valve cannot be manually turned off by turning the pump switch off, otherwise it could cause damage to your system.
Where Does the Check Valve Go on a Reverse Osmosis System?
The check valve is located at the point where raw water enters the system. The raw water enters the system through a hose and ends up in a membrane. The membrane allows only certain types of ions to pass through it into the pressurized water, which then goes into a storage tank.
How Do I Turn Off My Reverse Osmosis?
To turn off your reverse osmosis system, you should press and hold the Off button on the remote control panel. This will shut off the system when it detects a low flow rate.
Why Is My RO System Vibrating?
If your RO system is vibrating, it means the flow rate is too low. This can be caused by a clogged filter or malfunctioning system components. If you have an RO system that’s vibrating and not producing any water, then you need to check and make sure the auto shut off valve is working properly.
Why Does My Reverse Osmosis Keep Running?
The main reason that your reverse osmosis system keeps running is because one or more of the following are happening :
