Works great reducing calcium build-up!

We live in an area with very hard water. This filter system has reduced our work keeping faucets and black granite counter tops buy 95%! You will not regret buying this system.

Whole House

Great service, good product. Running well water through whole house. Water looks and tastes great. We change filters about every 6 months even though house flow is unaffected.
