Ro water storage tank pressure.
Locate the pressure valve under the blue cap on the tank.
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.
Disconnect the yellow line from the tank valve.
Point y on figure 1.
Use air compressor or bicycle pump to.

Turn off the valve on the reverse osmosis system supply line.
As water is used the pressure will drop until the shut off valve disengages allowing feed water to the ro system to resume until the tank is refilled.
Drain the old tank completely thru the spigot.
Pressurized storage tanks force water out on demand while atmospheric tanks require a booster pump to supply pressure.
Turn off the feed water supply to the ro.
Reverse osmosis systems utilize pressurized tanks to store purified water until the demand for the water is initiated.
Give the water storage tank a shake to make sure that it is empty.
Reverse osmosis storage tanks also keep the ro system efficient by turning the system on and off as the tank fills with water and pressure increases.
Close the tank s ball valve.
A water storage tank holds clean water from your reverse osmosis system or other filter systems until you re ready to use it.
Turn on the reverse osmosis water faucet and let the water run until it comes to a complete stop.
If your tank doesn t have enough pressure the valve won t work and water will keep flowing in and down the drain.

Water will remain in the bladder until the faucet is opened the air pressure surrounding the bladder will force the water out of the storage tank and a directed point of use.
Use an air pressure gauge to check the current air pressure.
If your city water pressure is around 50 psi the system will shut off water production when the tank reaches a pressure of 30 or so psi.
This also prevents water from draining.
Water storage tanks exist in a vast array of sizes designs and specifica.
