FAQ’s
Does this syem lter Fluoride, Lead, Pharmaceuticals, and Arsenic?
Yes, as well as Cyanide, Phosphate, Peicides, Sodium, Cadmium, Sulfates, and many other contaminants
up to certain levels. You may need other changes to media for high levels of these subances.
What PSI do I need? What is the operating pressure?
The minimum PSI for the syem is 40 and the maximum PSI is 80. If your PSI is too low you can purchase a
Booer Pumps to aid your syem. If your PSI is too high you can purchase a Pressure Regulator to reduce
your pressure to acceptable levels. Let us walk you through these options; call us at 1-800-992-8876 or visit

Does this syem soften water?
Your RO Syem will soften water. However, hard water does reduce the lifespan of your Filters.
Does it op lling automatically when lled? Why is the drain line conantly owing?
The RO Syem does op lling automatically when tank is lled (2-3 hours). If your drain line is conantly
owing this is a sign that your incoming water pressure is too low.
Can I inall this syem in the basement? If so, will it aect the eciency of the RO Syem?
Yes, the RO Syem can be inalled in a basement. However, if you do not have adequate water pressure
you may need to purchase a Delivery Pump. Contact Express Water and we’ll help you nd your solution.
What is the discharge rate?
The typical discharge range is one to three gallons for every one gallon produced. Your water pressure,
incoming water quality, and water temperature will aect your RO Syem’s discharge rate.
Why does it take so long to ll up the tank?
The purication process takes some time on its own. However, some water takes longer to process. Your
water pressure, incoming water quality, and water temperature will all aect how quickly your RO Syem
lls the Water Storage Tank.
How often do I change Filters? Is there an indicator?
The Sediment, GAC, Carbon Block, and Deionization Filters should be changed every 6 months. The RO
Membrane and Inline Carbon Filter should be changed every one year at the same time as the second
change of the 6 month lters. There is no direct indicator for lter changes. However, if you notice a drop
in water quality before the 6 months or 1 year mark this may mean that due to your water quality you lter
has degraded. If you reach 6 months or 1 year without noticing a change in tae you should ill change
your lter at this point as they are no longer viable.
Can I add additional lters to my current syem?
Yes, each syem is fully upgradeable. Check the Upgrades and Accessories section at expresswater.com for
more information.
Can I connect this syem to a refrigerator or icemaker?
Yes, you may need an Express Water Refrigerator Kit to do so. In some cases, your situation may require a
separate tank or Delivery Pump depending on how far away your refrigerator is from the syem. Contact
Express Water and we’ll help you nd your solution.
Can I reuse discharge water?
Never consume discharge water. With proper inallation it is possible to utilize your discharge water.
Contact Express Water to speak with a qualied representative who can give you more information based
on your situation.
How long does the syem la? How long does the tank la?
With proper maintenance and average water quality an RO Syem should la 5-10 years. The water orage
tank usually las 3-5 years before we recommend replacing it.
Can I change my 50 GPD (Gallons Per Day) syem to 100 GDP? If so, how?
Yes, to do so, you will need dierent parts (such as the RO Membrane and Flow Rerictor). Contact Express
Water and we will help you arrange your upgrade.
Why are there bubbles in the water?
Bubbles in your water is a common issue, but they only aect the appearance of your water and pose no risk.
There can frequently be air trapped inside any plumbing syem, so the air may be coming from your home’s
plumbing and not the RO Syem. Trapped air happens frequently when you change a lter, when there is a
leak in your syem or plumbing, or even when there is conruction in your area. Check your syem carefully
for any leaks or unexplained moiure. You may need to carefully tilt the syem various directions then set it
back in place to help release trapped air.
Does this produce aquarium safe water?
The Deionized water is safe for appropriate aquatic life. Be sure to te your water regularly to make sure it is
safe for your aquarium.
Why do I need to ush the syem?
New lters (or lters that have experienced extended disuse) can develop carbon residue. We recommend
emptying the Water Storage Tank four times (which can take 8-12 hours) to release any extra carbon before
the water is safe to drink.
How much water can the Water Storage Tank hold?
The maximum capacity of the tank is 3.2 gallons. However, the typical tank reaches 2-2.5 gallons. Your Water
Storage Tank’s capacity depends on your incoming water pressure. Lower water pressure means the tank will
hold less water.
