WORKING SYSTEM If your system is working you will see the following: 1) It takes approximately 3-5 hours for the tank to fill up depending on water pressure. 2) If the water tank is closed (blue tank valve switch is 90 degrees to the water tube), then the water coming out of your faucet will be almost needle stream ( or almost continuous drip of water). (remember to open up the tank switch after testing). 3) Use a TDS meter to measure the quality of the reverse osmosis water (treated) vs. tap water (untreated). Click Here For To Buy TDS meter.
NO WATER COMING OUT OF REVERSE OSMOSIS FILTER FAUCET Summary: The reverse osmosis system is a "very" simple design. To find out where the problem is, one need to follow the water flow to determine at which stage the problem exist.
Suggestion: Print out this instruction + Diagram below on paper and have it in front of you when doing diagnostics. Go through the checklist and confirm each point and write down what you see. You MUST go through each step below before calling us. This will save you time and save us time. When calling us, our technician will ask you to confirm each of the points below.
DIAGNOSTIC CHECK LIST
1. Check New Filters: You are replacing your old filters. After you inserted new filters and the system does not produce water or worst than before. Then maybe one of your new filters is defective. Disconnect at point 4b, to confirm that the water should be shooting out at very high pressure. If the pressure is slow, then one of the new filters may be defective.
2. Check Filters Plugged/Dirty: Point 2,3,4 this case, disconnect line at location 4b to confirm that the water comes out at a very strong water pressure (like a jet shooting out more than a meter). When the filter is dirty, it will reduce the incoming water pressure causing the system to fail. The tank will not fill up, the auto shut off box fail, and the water continues to drain.
3. Check Water Tank: Point 6a water tank pressure is too low, then not all the water can be pushed out of the faucet. If water tank pressure is too high, higher than incoming water pressure, then no water can get into the tank. The tank will be empty. The normal tank pressure when empty should be between 5-7 psi. The automobile pressure gauge that you use for your car tire cannot be accurately used for the tank. The air valve is on the side of the Tank and it functions are the same as the air valve on your bicycle.
4. Check Flow Restrictor: Point 5b There should be a plug (sometimes color plug) with a very small pinhole. Ensure that it is no damaged or missing.
5. Check Membrane: Usually the problem is not due to the membrane. However, ensure that you change it every 2-3 years.
6. Incoming Water Pressure: If ALL of the above is confirmed to be no problem, then your real problem is that the water pressure is too low for the system to work properly. The system works best with an incoming water pressure of 50-60 psi. If the pressure is too low, The tank will not fill up properly, the auto shut off box may fail and the water continues to run into the drain. The solution is to increase the pressure using a reverse osmosis water pump. Depending on water pressure, the tank can take 3-5 hours to fill up and for the system to shut down.
DIAGNOSTIC BY SCENARIO
1. Gradually there is no water over a time period. Almost 99% of the time it is because the filters are being clogged. Different areas can have different water quality, there can be a lot of dirt and sediment during different seasons or due to occasional nearby constructions.
Solution: Change filters
Pre-membrane filters change every 6-12 months. Membrane filter change every 2-3 years Post-filter every 1-2 years.
2. Suddenly there is no water.There is a water flow problem:
Solution: a) disconnect line at the different sections of the system to ensure water flow. b) check drain/flow restrictor to ensure that no excess water is being dumped into the drain.
3. New system but little or no water over 3 hours. If you have your own house water pump, then 99% of the time it is because the water pressure is too low.
Solution: a) Increase pump pressure to 50-60 constant water pressure. b) If you have good water pressure, then it could be the drain/flow restrictor. Usually, this is not the case with the new system. If it is damaged, then changed a new drain/flow restrictor.
4. Water in the tank, but no water or little water coming out of the faucet. What it means is that there is not sufficient air inside the tank to push water out OR the tank bag holding the water is broken. Solution: 1) Get a bicycle pump and pump air into the "side" valve of the tank. 2) When the tank is empty, it should be 5-6 psi. However, most pressure gauge measurement is not sensitive enough to give an accurate reading. 3) Pump sufficient air into the tank such that you get a good stream of water coming out of the drinking water faucet. 4) If you pump too much air into the tank, then the water will not be able to fill the tank. You must play around with it to get the right amount of air into the tank. or 5) If you see water coming out of the air valve on the side, then the tank bag is broken. In this case, you need to buy a new tank.
5. Water flows into the drain and never stops. Let the system run overnight with the faucet closed. Before opening the water filter faucet, check the drain line to confirm if water still continues to dump water into the drain. If yes, then check: a) If the tank is full but the drain water continues to run, then the Shut Off Box may be defective. b) If tank is empty, then the Drain Restrictor Line may be defective. 6. Why TDS of production water higher than the incoming source water When the system is properly installed and the lines are connected correctly. The production water should be 85-99% lower than the source water, depending on the type of system you have. The first step is to confirm that all the lines are correctly connected. Usually, the problem is due to the production line and the drain line being switched around.
How Much Water Tank Holds The tank with most of our system is 4 Gallon tank. It is generally more than a family of 4-6 needs. The actual amount of water in the tank depends on the incoming water pressure. The system stops producing water to the tank when the system pressure equals to the incoming pressure. The optimal operating pressure is 40 - 60 psi, with the higher range being the most efficient.
When Water Running Into The Drain Stops Wastewater is dump into the drain while the system is producing water good water. This is also the reason why you get such pure water from Reverse Osmosis. The wastewater will stop when the system can no longer push good water into the tank at the point where system pressure = to incoming water.
HOW TO CONNECT ALKALINE FILTER TO REVERSE OSMOSIS See Picture Below For Reference
1. See the Auto-Shutoff Valve (ASOV), that's the little square box with 4 connections. The system will be shut off by the valve when there is a balance between the Reverse Osmosis water tank and the water supply (i.e. when the water tank is full)
The diagram shows how the ASOV is hooked up to the reverse osmosis system. The Port 1 and 2 pair is on the side marked IN and OUT (known as the high flow pair). Port 4 and 3 are on the side with the 4 screws (known as the low flow pair). They must be hooked up to the correct configuration. Note port #3, it is connected to the post-filter and tank via a T-connector (or in alternate versions that do not use T-connector, it connects to the post-filter directly).
2. The mineral unit should go in-between port# 3 and that T-connector. Therefore, water flows out of port #3, into the mineral filter, out of the mineral filter, then into the post filter and/or tank.
3. To insert the mineral unit, you would remove the existing tube connecting port #3 and the T-connector. Then use a new line to connect port# 3 to the IN port on the mineral unit, and another line to connect the OUT port of the mineral unit to the T-connector. Or in the case of the 'alternate version', the OUT port of the mineral filter will connect directly to the post filter. NOTE: The physical Auto-Shutoff Box will not have #1, 2, 3, 4 labeled on its ports -- you will need to follow the physical tubes to figure which port corresponds to port #3 described above. The key is to find the post-filter and trace it back to the ASOB.
4. If a lot of water continued to flow out of the faucet when the water tank is closed:
a) Then you may have to check the drain water line. Ensure that the drain water line is connected to the correct output from the membrane housing. Also, ensure that there is a flow restrictor inside the drain water line tube.
b) If after verifying a) is correct, then you may need to check if the membrane filter is sitting correctly inside the membrane housing. If there is no membrane or if the membrane filter is not sitting properly, then you may have a bypass of water.
