Now there is no water flow?? What do i do??** A: Dear Ms. Nicole, Thank you for your business and for taking the time to contact Express Water. We look forward to assisting you with this matter. To better assist you, please check the following components to help determine the cause of no water production from the RO System: 1. Please check if the Feed Water Adapter Valve is in the open position with the red line pointing towards the tube. 2. Please check if the Leak Stop Valve has been activated, opened with the Textile Pad expanded. Should the Textile Pad expand, this will cause the Leak Stop Valve to be activated and incoming water supply to be closed off to the system and will result in no water production. The purpose of the Leak Stop Valve is to detect any leak(s) in the RO System and will shut the incoming water off preventing a small leak from becoming bigger. This will prompt you to check under the sink and be alerted of the initial leak. Please remove the expanded Textile Pad and discard as it may not be re-used, . Do NOT place a new pad until the leak is resolved. Please continue to monitor the system for the next 5-10 minutes for any leaks as the system starts to pressurize. If there is a leak, please determine the exact location of the leak and follow necessary troubleshooting steps to resolve the leak. Place a new Leak Stop Pad once all connections are secured and there are no leaks after 5-10 minutes of system startup. Please allow 2-3 hours for the Tank to fill. 3. To check if the system is working properly and producing purified water, please turn the Tank Valve into the "Closed" position pointing away from the tube. Proceed to turn the RO Faucet in the "On" position and let us know if there is any water coming out. It should be a consistent small stream or consistent drip (non-stop), depending on incoming water pressure. While the RO Faucet is on, do you hear any water going down the drain? If you do not hear any water draining, please place your hand on the black drain tube and there should be water flowing through the black tube and down the drain. If there is no flow out the black tube while the RO Faucet is on, please let us know as there may be a clog in the system. 4. Please check the Drain Line Tubing connection into the drain pipe and make sure that this tube is not restricted in any way to ensure free flow of wastewater. 5. Please lift the RO Tank and let us know if it produced a full tank of water or no water at all? If so, please check the tank pressure. We recommend emptying the water from the Tank and once it is empty, please proceed to add up to 10 psi max into the Tank. This should help increase the pressure of the water coming out of the Tank. Please do not add any more than 10 psi or you will not have any room for water storage as it will be mostly air pressure. If after doing all these tests you are still unable to find the cause of the problem, please let me know, as one of the filters might be clogging the system or maybe a misconnection somewhere in the system. We kindly ask if you could please provide the following information: Photo(s) of the system showing all the tubings and connections to have a better understanding of your set up.
