Water Treatment & Pump System Services

Failing well pumps, stubborn water quality issues, systems that were installed wrong and never worked right — our service team has seen it all, and we bring more than 125 years of hands-on regional experience to every job.

What We Service

What each service covers

Water Pump & Pump System Service

A pump system that underperforms or fails entirely can disrupt everything from household water supply to agricultural irrigation and industrial process operations. Our technicians service a wide range of pump types and configurations, including:

Submersible and jet well pumps
Pressure tanks and control systems
Sump pumps and sump pit systems
Water pressure booster systems
Irrigation and agricultural pump systems
Sewage and wastewater pump systems
Water storage pump configurations

We diagnose the root cause rather than replacing parts at random. Accurate diagnosis saves time and money, and it produces repairs that last.

Filtration, Softening, Purification & Disinfection

Water quality problems take many forms. Hard water scales your pipes and shortens the life of water-using appliances. Iron, sulfur, and sediment affect taste, odor, and clarity. Bacteria and other biological contaminants require disinfection systems that are properly sized and maintained. Our service team handles:

Water softener service, resin replacement, and system recalibration
Filtration media replacement and housing maintenance
Reverse osmosis membrane service and system sanitization
UV disinfection system inspection and lamp replacement
Chlorination and chemical feed system maintenance
Whole-house and point-of-use system troubleshooting

Whether a system was installed by Rock City Machine Company or another provider, we can offer advice and evaluate its condition and restore proper performance.

Two Different Demands

Residential water systems and industrial water systems share the same basic principles but differ significantly in scale, complexity, and the consequences of downtime. A homeowner dealing with low water pressure faces an inconvenience. A manufacturing facility or agricultural operation dealing with the same issue faces production loss.

Rock City Machine Company's service team is experienced in both environments. We understand the regulatory considerations that apply to industrial water systems, the capacity demands of commercial operations, and the practical priorities of a homeowner who simply needs reliable water at the tap. That range of experience makes our technicians sharper diagnosticians.
