Bought myself an RO system that is just cannot stop leaking and draining after installed. Called him after reading the reviews. He was courteous and explained what he was doing, found out that one of the valves caused the water to drained at all time, he removed it and re-route it so the system works and works more efficient. He re-installed the system. He cleaned up after he was done. Very humble guy. Now we have working RO with no leaks. His rates are the same as any RO tech, but your money goes to supporting a Veteran.
