Then, check if O-ring is properly in place.The o-rings may be a little too small, please stretch it out and put it back inside the groove. You may over-stretch a little sowhen it is back to the canister, it will shrink and fit just right. Then insert the cartridge to the top cap, screw the canister all theway up. MAKE SURE O-RINGS are staying in place during this process. Then use a wrench to tighten (no need to overtighten it).Little water out of faucet, tank is heavy and appears full of water, but the streamturns very weak after a few secondsIf there is no change in the supply water pressure, the problem is very likely from the tank. It could be due to low tankpressure or broken bladder. Perform the following steps first?• Shut off main water supply• Get a bucket under the tank and remove tank by disconnecting the ball valve.• Dump the water from the tank by turning it upside down (through the top stem). You may addair from the front valve to help emptying the water.• Use a gauge at the front air valve to check tank pressure. It should be within 7-10 PSI. If toolow, you can use a bicycle pump to add more pressure to the tank.• Re-connect tank to the system and turn on the water supply.Continuous drainAll RO systems create drain water. The drain water should run only when the system is making water. The ratio of drainwater to RO water is about 0.8-3:1 for our RO systems (Pumped, Side-Flow systems have lower ratio). For a regularresidential household, the waste water per day is about 3 more flushes of toilet, which is not too bad. The drain should stopafter the tank is full. Allow 3 hours for the tank to fill up. If the drain is still running, the problem might be caused by thefollowing reasons?• Faulty automatic shut-off valve (ASV, the white square valve that connects to 4 tubings),• Faulty check valve (at the pure water outlet of the membrane housing),• Faulty flow restrictor (the small tube that marks "flow 300" and connects to the drain line).• Low tank pressure.High TDS level in RO waterThe RO system should produce a TDS rejection rate of about 85-95%. Check the following first?• What is tap water TDS reading? Is there a sudden increase in tap water TDS level.• Has the RO membrane been installed? It is packed in a vacuum plastic bag and in blue color,located in the accessory box.• Possibility of reverse drain line and pure water line. Compare your tubing connection to thediagram on the manual and check. |
