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 GPD? 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?
For Alkaline Syems it is normal to have more bubbles in your water because of the higher oxygen content.
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?
Alkaline water is NOT safe for aquatic life. The PH and minerals of Alkaline water are not good aquariums,
while the water is perfectly safe for human consumption.
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.
What other lters can I add to my syem?
Express Water oers many upgrade lters including a UV Sterilizer, a Deionization Filter, an Alkaline
Mineralizer, and other options. You cannot normally use a deionization lter and alkaline lter together, but
it is possible to use them on one syem separately. Contact us if you have any queions about additional
drinking water or whole house ltration.
What if I need to produce more water?
There are a lot of solutions to this problem, it’s possible to upgrade your drinking water syem with some
specialty equipment or we can help you with other solutions. Ju contact us and we can help you nd the
solution that be ts your home.
What should I do in a boil water advisory?
As long as all of your lters are working properly you can drink water from your RO syem without boiling.
However, you should replace all of your lters after the order is lifted. While the syem will tler large amount
of harmful agents it can damage your lters and cause bacteria to grow. You should follow sanitization
inructions when replacing the lters.
