Well Services in Ontario

Well Pump Repair

When your well pump fails, every hour without water is a crisis. Our experienced technicians diagnose and repair pump problems quickly, carrying common parts on our trucks for same-day repairs whenever possible. We service all pump types including submersible, jet, and booster pumps.

Pump Replacement

If your pump is beyond repair or has reached end of life (typically 8-15 years), we provide complete pump replacement services. We'll recommend the right pump for your well depth and water needs, install it professionally, and ensure your system is running perfectly.

Pressure Tank Service

Waterlogged or failed pressure tanks cause pump short-cycling and inconsistent water pressure. We diagnose pressure tank problems, adjust air pressure, and replace tanks when needed. Quality bladder tanks last 10-15 years with proper care.

Electrical Troubleshooting

Many well problems are electrical—failed pressure switches, burned capacitors, or bad control boxes. Our technicians systematically troubleshoot electrical issues, often resolving problems the same day with parts from our service trucks.

Water Testing

Know what's in your water. We provide water testing services for bacteria, nitrates, minerals, and other contaminants. Results help identify if treatment is needed and what type of system would work best for your water chemistry.

Well Rehabilitation

If your well is producing less water than it used to, rehabilitation can often restore production. Methods include hydrofracturing, chemical treatment, and mechanical cleaning—often at a fraction of the cost of drilling a new well.

Wells on Record

San Bernardino

County

Based on California DWR well completion reports. Ontario's average well depth is close to the San Bernardino County average of 380 feet.

With 376 wells on record, Ontario has a moderate well infrastructure. The wide depth range of 3 to 1260 feet reflects the varied terrain and geology across Ontario's landscape. Shallower wells typically tap into alluvial aquifers near drainages, while deeper wells penetrate Mojave Desert alluvial basins and Transverse Ranges crystalline rock to reach more reliable water sources.

At an average depth of 330 feet, well maintenance in Ontario is essential for protecting your investment in a 330-foot well. See detailed well depth data for Ontario →

Well Maintenance in Ontario

Regular well service in Ontario helps prevent costly emergency repairs. With local wells drilled through Mojave Desert alluvial basins and Transverse Ranges crystalline rock, we recommend annual checkups that include water level measurement, pump performance testing, pressure tank inspection, and water quality screening.

Ontario well owners should watch for signs of trouble: reduced water pressure, pump cycling frequently, discolored water, or unusual noises from the pressure tank. These often indicate issues that are much cheaper to fix early than after a complete system failure.
