Q. ONCE MY H2RO SYSTEM IS INSTALLED, DO I HAVE TO DO ANY MAINTENANCE?

A. Yes, immediately after installation, you should:
- make sure your installer sanitized your tank. If it has not been sanitized, please do so. (See the Installation Instructions for instructions on how to do this.)
- do not drink your water immediately. Let your tank fill up and then empty it. Repeat once. This will flush out the system

One week after installation, you should test your water for Total Dissolved Solids.

Once a week after installation, you should open your tap and drain the tank completely. (To conserve water, you can store it in jugs and use it for drinking, watering your plants, etc.) This flushes the tank and allows the system to produce purer water.

Once a year, you should:
        - weigh your tank to make sure its inner bladder has not developed a leak. (See Answer to Next Question)
        - sanitize your tank. Please click here for instructions on how to do this.
        - test your water for Total Dissolved Solids.

Every 3 years, you should change your pre-filters. (See Answer to Next Question)

Every 6 years, you should change your membrane, capillary tube, and post-filter. (See Answer to Next Question)


Q. WHAT IS THE REPLACEMENT SCHEDULE FOR THE COMPONENTS OF THE H 2RO SYSTEM?

A. Because you have an Automatic Shut-Off Valve, the H2RO System will "sleep" most of the time.  The following estimates presume you have a properly functioning Automatic Shut-Off Valve:

Pre-Filters.  Unless the filters become clogged, and the water production slows down, you should change the filters every three years.  The first filter is a 5 micron sediment filter.  The second is a 1 micron carbon briquette cartridge.  Since the carbon briquette cartridge removes chlorine, failure to change it every 3 years may allow chlorine to destroy the membrane.  (Note: Only a quality carbon briquette cartridge is adequate to protect the membrane from chlorine for three full years.  A cheap one may remove chlorine for only six months.)  How to Change Pre-Filters

Membrane.  Depending upon the water it is treating, the Special Performance membrane has a average life expectancy of 6 years.  However, a membrane may go bad prior to 6 years.   One indication is a gradual reduction in water production caused by a layering of minerals and salts on the membrane surface.  Another is a gradual deterioration in the quality of water being produced.  You may notice a different taste or more white scum on the inside of a pan of water you are boiling.  This might mean the R.O. membrane is disintegrating and requires replacement.  (Note: If the water starts to taste bad, try emptying out the tank. Then taste the fresh water being produced to see if it is any better.)  Remember, keeping the tank empty will usually result in better quality water. If in doubt, contact your dealer to test your water. How to Change your Membrane

Post filter.  This should be changed when you change the membrane.

Tank.  The Amtrol tank is guaranteed for 5 years, and normally lasts about 8 years.  However, the tank contains an inner bladder which could develop a leak at any time.  The standard Amtrol tank is called a 4.4 gallon tank, although it normally holds about 3.2 gallons, depending upon your water pressure.  Its dimensions are 14" high by 9" in diameter.  If you open your faucet and empty your tank completely, the tank should weigh less than 10 pounds.  If it weighs more than 10 pounds, then it's likely that the bladder is leaking and water is in the tank outside of the bladder.  You should stop drinking the water -- because it may be contaminated -- and get a new tank.


Q. MANY COMPANIES SUGGEST THAT PEOPLE CHANGE THEIR FILTERS AND MEMBRANES EVERY SIX MONTHS. WHAT ARE THE REASONS WHY YOUR FILTERS AND MEMBRANES LAST LONGER?

A. Your water will first enter the sediment filter, which will remove the dirt, sand, etc. from your water. With average water, our customers have not had to replace this until after 3 years of use. (If you do have unusally bad water, your sediment filter will become clogged sooner than this, but you will know when this happens, because the flow will be drastically reduced. If you do decide to replace it, we will sell you the filter for $3 plus shipping -- no handling fee.)

Your water will then enter the carbon filter, which will remove the chlorine from your water. The manufacturer represents that it will process 20,000 gallons of water before it needs to be changed. (The filters sold by many of our competitors are only rated for 500 gallons.) We estimate that the average household uses 2 gallons of drinking water per day, but it takes a total of 7 gallons of water to produce 2 gallons of drinking water (5 gallons clean the surface of the membrane and go down the drain). If you take the 20,000 gallon figure and divide by the 7 gallon figure, that equals 2,857 days. If you divide 2,857 days by 365, that equals 7.8 years! (You will know when this filter stops doing its job because you will be able to taste the chlorine in your water. If you do decide to replace it, we will sell you the filter for $15 plus shipping -- no handling fee.)

Your water will then enter the FilmTec membrane, which has the highest rejection rate, is the fastest flowing, and the longest lasting. FilmTec is the "Cadillac" of all membranes made in America. It has a reputation for resistance to bacteria and chemicals, and usually lasts 2 or 3 times longer than most other brands. (Companies like Culligan include a FilmTec membrane in their R.O. systems -- though they charge you more for it than we do.) Under normal circumstances, our residential customers have not had to replace this until after 6 years of use. (You will know when the membrane stops doing its job because you will be able to taste the difference in your water. If you do decide to replace it, we will sell you the membrane for $55 plus shipping -- no handling fee.)

Your water will then enter the tank and then go to your post-filter. This removes any remaining traces of bad taste and odor. However, since it is processing pure water, it will last a long time. Our residential customers have not had to replace this for several years, but we recommend that you replace it when you change your membrane. (When you replace it, we will sell you this filter for $8 plus shipping -- no handling fee.)
