REVERSE OSMOSIS TDS TEST

REVERSE OSMOSIS LOW WATER OUTPUT FROM SPIGOT

Usually when a Reverse Osmosis (RO) unit is not putting out a decent amount of water (approx 2 gallons) after filling overnight, it is usually because water in the tank is not being pushed out by the air in the tank.

 

Do not turn off any valves  under the sink as you are doing this very simple procedure:

 

To check the tank, turn the RO spigot ON and let it run until the water flow slows to a trickle. If the RO storage tank still feels heavy that means there is water remaining in the tank and it is not being pushed out properly. If the tank feels light, the low volume of water is not due to low air pressure in the tank.

 

If the tank feels heavy, LEAVE THE RO SPIGOT IN THE ON POSITION and use a bicycle tire pump (preferred method) or an air compressor to add air to the tank gradually as water is expelled out through the RO spigot…

 

The air valve is usually covered by a blue plastic cap and looks like a bicycle tire air valve when the cap is removed. If water comes out of the air valve when you take off the cap, the tank is bad…

if air goes through the tank as you add it and out of the spigot, the tank is bad…

 

 

Add air gradually until the tank feels light (10 psi MAX). DO NOT EXCEED 10psi !!! If you don’t have an air pressure gauge that will read accurately as low as 10psi, just add air gradually as water is expelled out through the RO spigot until the tank feels empty.

 

If this solves the problem, but only temporarily like a few months, then the tank is bad. If you can go a year before adding air again during the yearly filter change, then it is probably not worth replacing the tank.
