Hard water used for bathing dries skin and leaves hair looking limp. Roto-Rooter installs and services water softeners, which alleviate the damaging qualities of hard water.

Salt-free water softeners
Dual-tank water softeners
Magnetic water softeners
Reverse osmosis water softeners
Shower head water softeners
San Antonio’s water supply comes from the Edwards Aquifer, the Vista Ridge pipeline, and reservoirs. Local water meets state and federal safety standards but may contain trace amounts of nitrate, disinfection byproducts, and carcinogenic PFAS. A water filtration system helps ensure your home or business has the best possible water quality.

Paul was timely and very professional. He is someone who impressed us by his strong sense of responsibility. We want to make him our 'go-to' plumber.
Linda Y.Very professional Technican
Brian M.The technician arrived on time and quickly assessed what was needed to stop the water leak. The repair was made and work was completed in one hour. Another ... plumber had told me that the area the leak was in would need to be excavated which was incorrect. He recommended another plumber which could not be on site for three days which was no help at all since we had no running water. Next time I won't bother with them I will just call Roto-Rooter.
