Mr. K. called to set up a time for his yearly filter change on his Ultroflo Reverse Osmosis system. Shae, our tech, was able change the 3 yearly filters for him. They did also notice it was time to change the membrane on the unit as well. That filter should be changed every 3 to 5 years on that system. He also tested the water and did a tune up on his water softener. Everything looked good!
