Section 2: Troubleshooting Guide
Leaking from where the tubing is pushed into the quick­connect fitting
It is very likely that the tube is not fully inserted into the fitting. If you remove the tube and look inside
the elbow fitting, you will see a small black O ring. If the tube is not pushed past this O ring, no seal
will be created. To make sure you are getting the tubes pushed in past the O ring, make a ½" mark on
the end of the tube. When inserted properly, the tube will be inserted to this mark. You will get
resistance when you reach the O ring initially, but wiggle the tube and use extra pressure to get it past
the O ring. You will feel it go in further when you do so. Once the tube is in all the way, re insert the
blue clip on the elbow fitting. If this does not fix the problem, switch out the elbow fitting for one of
the extras that came with the system. Before replacing, wrap the new fitting thread 2­3 times with
Teflon tape to ensure a proper seal.
Leaking around filter housing (O­ring is too small or is not in place)
Please check to make sure all of the filter cartridges are sitting upright inside the canisters. Then,
ensure the O­ring is properly in place. The O­rings may be a little too small, please stretch it out and
put it back inside the groove. You may over­stretch a little so when it is back in the canister, it will
shrink and fit just right. Then insert the cartridge to the top cap, and screw the canister all the way up.
MAKE SURE O­RINGS are staying in place during this process. Then use a wrench to tighten (no
need to over tighten it). If the membrane housing is leaking, please make sure the O­ring is seated
correctly as shown in the manual. It should be seated on the end of the membrane housing before the
threads begin. When in the correct place, there will not be any pressure or tension on the O­ring.
Low water pressure at the RO faucet or output location
● Have you given the system enough time to fill up the tank? If you just installed the system, give
it 1.5­2 hours to fill the tank.
● What is the total distance between the tank and the output location? If it is over 15 feet or going
vertically, the pressurized tank is struggling to push out the water at an adequate pace. Shorten
the distance beetween the tank and output location, or add a delivery/demand pump to assist
with the output. Do not confuse this with a Booster Pump which is only for raising the INPUT
pressure.
● The stage 5 Post Carbon Filter is clogged and needs to be replaced.
● If you are dispensing the RO water through your refrigerator, remove the filter that is currently
installed in your fridge.
● What is the incoming water PSI to your home? If it is below 45 PSI, we recommend getting a
system with a booster pump so the reverse osmosis process can be performed correctly. If you
water pressure is below 45 PSI, there will not be enough water pressure to push the water
through the RO membrane on a continous basis.
● Incorrect air pressure in the tank. Shut off the main water supply to the system, and open the
faucet to drain the tank. After the faucet stops dripping, close the tank valve, remove the
connected yellow tube, and take the tank outside or somewhere that can get wet. Remove the
tank valve from the top of the tank, and turn it upside down to drain out any remaining water.
Then, use a standard tire pressure gauge to check the air pressure at the nozzle on the bottom
half of the tank. The air nozzle is under a screw off blue cap. If the pressure is not between 7­10
