:—The one and only cause for an anode to be dissapated is DC electrical current. The higher voltage level present, the faster will be the consumption of the sacrifical anode.
Normally a water heater anode has to deal with voltages in the millivolt range. There can be external forces at work in your particular case. If there is an improperly grounded appliance that has a solid state timer or control device that is impressing a DC charge into your Plumbing loop, efforts should be made to find it. When the anode is no longer available for the corrosion process to munch on, it will shift gears and develop a taste for Copper or other metal within that system. Check your premises for battery chargers(like those used for cell phones) and rechargeable cordless phones, or other DC producing devices or appliances,
Most water heaters carry a 5-year warranty on the tank against failure. Contact the supplier for a possible adjustment. It is important to resolve this spurious voltage situation before you start to develop pin hole leaks in your copper piping.

Specifically, which contaminants does a Reverse Osmosis system remove?
A Reverse Osmosis system can treat for a variety of contaminants including:
Aluminum, Arsenic, Asbestos, Atrazine, Benzene, Chlorides, Chlorine, Copper, Cryptosporidium, Cyanide, Fluoride, Giardia, Lead, Mercury, Nitrates, Radium, Radon, Silver, Sodium, Sulfide, Trichloroethylene, and Total Trihalomethanes.

Many people have heard of reverse osmosis and know that it can be used to treat water to a high degree of purity, but their understanding of the technology ends there.

To understand reverse osmosis (called “RO” for short), it first helps to understand the natural phenomenon of osmosis. Simply put, osmosis is the flow or diffusion of a fluid–generally water–through a semi-permeable membrane.
