The number one reason for low water flow from a reverse osmosis system is low air pressure in the holding tank.
( Note: Reason number two is clogged pre-filter, so check that too ).
The Problem: Low Volume and Poor Pressure
Little to No air pressure will result in very little water being pushed out of the holding tank. You will have a full and heavy holding tank, but without the air pressure, you'll never get much water out of the tank. Too much air pressure ( say over 10 psi on a small tank ) will result in good water flow but will severely limit the amount of water that can be stored in the holding tank. So, it is recommended to put 8 psi of air in your under the sink reverse osmosis holding tank. If you get water coming out of the air valve, then it is time to purchase a new holding tank.
To Check:
With all possible water drained from the holding tank, you want to get an air pressure reading of 8 PSI of air pressure. There is a "tire" valve on your holding tank somewhere ( usually the bottom ). You really should use a special low pressure air gauge. One that shows the air pressure in one pound increments starting with one pound. The average tire gauge starts at 5 or 10 lbs. psi.

Tank Replacement Questions and Answers:
Do you just hook up the tank and start using it? If not, will it come with instructions?
* Simply turn off the RO incoming water, open your RO faucet to relieve any pressure. Disconnect tubing at the Tank shut off.
* You will unscrew the shut off elbow that is on your old tank and you can re-use it on your new tank.
Just be sure to use about 3 layers of Teflon Tape on the threads of the new tank,
AND do not over tighten the elbow fitting, or you will crack it.
We sell new shut off elbows, and they should be available locally where ever plumbing supplies are sold.
The thread size on the tank is called 1/4" mpt. And the tubing size connection will be either 1/4" or 3/8" O.D. ( depends on what size your system uses, both are common ).
* Also note, the tank comes pre-charged. You should not need to add any air to it.
