Hard Water in Pipes

Problemwater.com is here for you with the best solution to your problem water. Our heavy-duty water conditioning products have been proven on the tough well water of California’s Central Sierra Nevada foothills where we have been cleaning up problem water since 1982.

Problemwater.com is owned and managed by Joe Stern Water Conditioning, a fully operating water treatment service company located in Oakhurst, California. The area’s naturally high mineral geology often results in excessive amounts of unwanted problem water minerals such as iron, manganese and hydrogen sulfide gas.

Joe Stern, owner and founder of the company, has had years of experience installing and servicing water treatment equipment in the surrounding Mariposa and Madera Counties. The very high percentage of private wells in these two counties combined with our high mineral geology have provided us with an excellent opportunity to see just exactly which filters work best on various types and amounts of iron, manganese, hardness, hydrogen sulfide gas and other problems.
