Locate the pressure valve under the blue cap on the tank.
Apec water tank air pressure.
Open the unit s tap and allow the water to run until the tank is empty.
The water reservoir can hold up to 4 4 gal.
Use an air pressure gauge to check the current air pressure.
If the cold water shut off valve can not turn off the water the main water supply to the house must be shut off for the installation.
This tank took less than 15 minutes to install and now we re experiencing full pressure and volume.
As water fills the tank air pressure should increase steadily to 35 40 psi which triggers a check valve that stops water flow into the tank.
When i checked the air pressure in the old tank water flowed from the schrader valve a sure sign that the tank s bladder had failed.
Of water at once with the rest of the storage area being occupied by the pre pressurized air bladder which helps you draw water from the tank.
The pressure in an empty tank should be eight pounds.
If you have little to no water flow it is usually the result of one of two things.
Give the water storage tank a shake to make sure that it is empty.
Close the tank s ball valve.
And i saved 150.

Steel connectors ensure leach free integrity while post cured diaphragms eliminate the possibility of odors from the tank.
This also prevents water from draining.
If the pressure in the tank is too high water will be unable to enter from the filters.
This tank comes with a free tank ball valve and a free tank stand.
Use air compressor or bicycle pump to re pressurize the 4 gallon tank to 5 psi and 7psi for the 14 gallon tank.
Either the water pressure is low or the volume of water is low.
Like we mentioned above an empty ro tank has pressure of 6 to 8 psi.
Check the pressure of the emptied tank with a low pressure tire gauge.
Point y on figure 1.
If your tank doesn t have enough pressure the valve won t work and water will keep flowing in and down the drain.
Our standard ro water tanks offer quality water storage for use with our residential reverse osmosis systems.
Another option is to use a self piercing saddle valve from apec or from a local hardware store.
If the tank still has water in it locate the air valve on the tank that is just like one on a bicycle tire and give it 6 pumps of air with a bicycle pump and let it empty.
Use a pressure gauge to check the air pressure in the tank.
A water compartment and an air compartment.
Disconnect the yellow line from the tank valve.
How reverse osmosis tanks work.
This type of problem is usually caused by a storage tank that has malfunctioned.
The air compartment is pressurized and as you open the tap the air pushes on the water and it flows out through the tap.
Ro pressure tanks have two compartments inside them.
