Ensuring Against Leaks:
This section will explain how to fix any potential leak on your Reverse Osmosis System.
Threaded Fittings:

Example: Aquasafe's Elbow Adaptors
To prevent a leak on any threaded fitting that screws into the Reverse Osmosis System you simply need to employ Teflon Tape.
The Main instructions Pages Indicates the preventative measure of wrapping the threads of the Various Threaded Fittings 4-5 times with Teflon Tape.
This Preventative Measure will Ensure against any potential leaks from the various threaded fittings throughout your Reverse Osmosis System.
Adding Sufficient Teflon Tape is Key.
If you are experiencing a leak from the 1/4″ tube inserted into the various threaded fittings, you simply need to insert the tubing into the threaded fitting further. To do this you may need a small pair of pliers to assist you in gripping the tube.
If the use of pliers is needed, grab the tubing 1/2″ from where the tube inserts into the threaded fitting in order to not score the section of tube that will be inserting further into the threaded fitting. A scored section of tubing that is inserted into the threaded fitting can act as a path for water to flow, which in turn may result in a small leak.
Pre-Filter Canister Housing

Aquasafe Prefilter Canister
All Reverse Osmosis Pre-Filter Housings Are “Compression Sealed”. This means that 99% of the time any leak coming from the threads of the Pre-Filter Housing Can be easily fixed by tightening with the Systems “large Canister Wrench”.

D.I Resin Canister:

DI Resin Canister
Sometimes the DI Resin Beads can get caught up in the threads of the canister and in the DI Canister Cap. Brush away all of the DI Resin Beads from the DI Canister Housing and rinse out the lid.
Once the threads of the DI Resin Canister are free of all DI Resin Beads a leak coming from the DI Canister can be fixed by tightening the lid as much as possible. Get a cloth to help give the grip needed for tightening purposes.
If for some reason you are still having trouble with one end of the DI Resin Canister, you can apply a small amount of silicone (the non-hardening variety). The Key to this method is using a SMALL amount. Do not silicone both ends as you will need to change the resin beads in the future.
Flow Ratios Between Discharge and Recovered Purified Water:
Setting the water flow ratios is very easy but requires some explanation. Please read the instructions found below.
PLEASE NOTE: Before attempting to disconnect the tubing from any fitting, shut off the feed water supply to your system. You will also need to turn the Tank Top valve to its horizontal (OFF) position. Lastly open your faucet to neutralize the pressure inside your water filter system. This will allow you to work on your system easily and without any water mess.
In order to set the flow restriction, you will need to visually judge the flow rate of water discharging through the yellow discharge water line.
Disconnect the yellow tubing from the drain and place it into a bucket (or the like). Next, turn the dial on top of the E – Z Flush Flow Restrictor counter clockwise (Left), entirely opening the Valve. The E-Z Flush Flow Restictor is depicted in the picture below.
NOTE: To Restrict the flow of discharge water passing through the E-Z Flush Flow Restrictor turn the dial to the right. (Clockwise) To increase the flow of discharge water passing through the E-Z Flush Flow Restrictor turn the dial to the left. (Counter-Clockwise)
Now turn the source water to your system back on. PLEASE NOTE. This will allow water to flow into the yellow discharge water line that you have placed inside the bucket as noted in the step above. Now you simply need to visually judge the flow of water that is coming through the yellow discharge water line and restrict that flow by no more then 33-45%. Once you have achieved this flow restriction ratio, you may once again shut off the source water to your system.
You have now set the flow restriction of your system. You may now hook-up the system as normal. Once you are sure your system is hooked-up as normal you may turn the source water to your system back on and open the Tank Top Valve to its ON Position.
Further Points:
The restriction applied to the water passing through the E – Z Flush Flow Restrictor is directly related to how much water will be forced through the Reverse Osmosis Membrane to become the Ultra Purified Water you seek. No flow restriction equals no water being forced through the Reverse Osmosis Membrane.
The flow restriction applied should never exceed 50%. It is important for the Reverse Osmosis Membrane to be able to flush away all of the toxins and contaminants it is removing and it does this via the water that is permitted to pass through the E – Z Flush Flow Restrictor to become discharge water.
The ideal ratio between the discharge water and the purified water for most clients is a 3:1 ratio where 3 parts is discharge water and 1 part is Purified water produced. To put it another way you would get 3 gallons of discharge water to every 1 gallon of Purified water Produced.
The maximum ratio of purified water produced to discharge water produced should never exceed 45% Purified water to 55% Discharge water.
Rest easy knowing that your system is designed to be fully automatic. When the storage tank for your system is full, the Auto Shut off Valve will activate which will cease all flow of water through your system. When you take purified water from your system the Auto Shut off Valve will auto trigger the flow of water once again throughout your system until your the holding tank is again full where it will then activate to shut off the flow of water. This cycle will repeat every time you take water from your system for your convenience.
In this way, discharge water will only flow when the system is producing the purified water you desire.
Removing Tubing from any fitting on your Reverse Osmosis Water Filter System:
To remove tubing from any fitting on your system please follow the below diagram:
Please Note: Depressurize your system before removing tubing from any fitting on your system.
To Depressurize your system you simply need to turn the Reverse Osmosis Manual Shut Off Valve to its Horizontal Position, then turn your Tank Top Valve found on the water Holding Tank to the Horizontal Position and then press down on your faucet. Depressurizing your system is extremely easy and takes just seconds.
You can easily remove the tubing from any fitting on your system by removing the Blue “C” Clip which will expose the “Collet”.. Then simply push in the Collet so that it is flush with the fitting and then pull out the tubing. You can click on the diagram above to enlarge the picture.
Increasing the PSI within your Reverse Osmosis Water Filtration System:
Increasing the PSI within your Reverse Osmosis Water System will increase the production rates of the purified water you seek to a maximum production capacity of 100 GPD. If you are on city or municipal water supply then most likely you do not need to increase the water pressure as 90% of city or municipal water sources have greater then 50PSI water pressure supplying the plumbing within your home which is adequate water pressure to produce 100 GPD of ultra purified water.
There are only two reasons for needing to increase the PSI (pounds per square inch of water pressure) within your Reverse Osmosis Water Filter System.
- If you have very turbid water that is murky and full of dissolved solids you may need to Purchase a Booster pump in order to increase the water pressure throughout your system.

TDS Meter
If you have a TDS (Total Dissolved solids) reading of 700-1000+ it is advisable to purchase a Water Filtration Booster Pump. We also highly recommend TDS meters to all of our clients.
Aquasafe Booster Pump
- If you are on a well system where your water does not come from your local city or municipality, but rather from the ground, your water pressure may be below 50PSI. Its important to note that your system will produce purified water ay 40PSI but the GPD (Gallons Per Day) production capacity will not be at 100GPD and the auto shut off valve may not function correctly. The solution to this problem is to buy a booster pump or if possible to turn up the output pressure of your well systems water pump.
Information on Your Water Holding Tank:
Water being produced by a Residential Reverse Osmosis Water Filtration System happens slowly. Even with a high grade 100 GPD (Gallon Per Day) Reverse Osmosis Membrane made from FilmTech Materials, the optimum water production rate is still just over 4 Gallons Per/Hr.
People do not have the patience to wait for a cup of water to fill, hence the 3.2 Gallon Water Holding Tank. In this way the tank fills in about an hrs time and delivers a steady stream of purified water which fills a Ten oz glass in just seconds.
Leaching of heavy metals into drinking water imposes health risks. As a result, brass. lead and copper are banned from use in purified/drinking water filtration systems. All Aquasafe water storage tanks are made of high grade stainless steel in order to avoid these leaching concerns.
All Aquasafe water storage tanks are NSF approved under standard 58, and CE approved under the PED (pressure equipment directive), because of these approvals our tanks carry the appropriate markings and can be used everywhere in the world.
- Your water storage tank’s air bladder comes factory set at 7psi. The air pressure within your water storage tank is what pushes the water from inside the tank to your Aquasafe Reverse Osmosis Faucet. Do not decrease the air pressure inside your water storage tank below 7psi, noe should the pressure be increased within the water storage tank past 9psi.
- Over 2-3 years time the psi within the air bladder may decrease. This potential decrease in air pressure will lead to much slower flow rates of purified water from your Aquasafe Faucet.
- If you do ever experience slower flow rates then normal, please see our trouble shooting section for the easy to follow quick solution to increasing the air pressure within your water storage tank to its factory setting.
