Reverse Osmosis Storage Tank Not Filling Up

The ro storage tank check the tank to see if it s full of water or not.

Reverse osmosis storage tank not filling up. Close the water supply valve. A simple tire gauge applied to the air valve under a blue cap on the side of the tank will give a close reading. It only drains water when it s filling up the tank. Wash the inside of the filter housing with warm soapy water.

Turn on your feed water line. Because the reverse osmosis filtering process takes time storage tanks are a necessary component with any ro system. You can measure air pressure via a low air. Low air pressure in ro tank.

Shut the reverse osmosis faucet off and let the tank fill up for 3 hours. The right pressure should be around 5 7 psi. Continue to enjoy your reverse osmosis system as usual. Open the faucet and drain the storage tank.

The most common reason for reverse osmosis tank not filling is due to insufficient air pressure in the storage tank. In the pnrv18 model the tank holds approximately 1 5 gallons and in the pnrv model it holds 2 1 gallons. Clogged or fouled water filters is the most common cause for a slow filling ro tank. If the air pressure in your storage tank is not around that range then water will not fill smoothly.

Turn off the feed water line to the system. Close the faucet after the tank has drained. Sometimes water will keep draining even after the tank is full causing a lot of water wastage and creating a continuous gurgling. Much like the tire on a car the rubber bladder on the inside of a reverse osmosis storage tank can lose pressure over time.

Please note that there are two valves one is the air pressure valve and the other one goes to the reverse osmosis membrane. Disconnect the red tubing at point d. For the most part reverse osmosis filters don t require much maintenance. Grab an empty bucket or container to catch the water coming out from the tubing.

Allow four hours for the tank to fill and try again. Do not remove the valve going to the membrane. 5 reasons you may have slow flow rates from your reverse osmosis system. Some of the water gets into the tank while reject water goes down the drain.

Please follow the flow rate test below. The ideal pressure for an empty tank should be between 6 to 8 psi for a 2 4 gallon tank. Put on a pair of clean rubber gloves to handle the new ro membrane. It should be 5 7 psi.

Look at pictures of installation that show feed connection and drain connection. The water pressure decreases as the tank gets near empty since the reverse osmosis filter produces water at a slow rate. With a storage tank you can quickly fill your glass pot or water bottle. Unscrew the filter housing and remove the ro membrane.

If the tank is not filling on your ro 45 or ro 90 clogged filters or components can be the factor. Check your tanks pressure with a psi gauge.
