Pressure system cleaned up and upgraded.

We replaced the old galvanized pressure tank and unsupported above-ground plumbing, rerouted the piping underground, added a riser for future connections, raised the pump, and repaired the cracked well casing.

The old galvanized tank relied on an air-charging system using two bleeders, a check valve, and a snifter valve. Because air gradually dissolves into the water, the system has to replenish that air as the pump cycles to maintain the proper air charge.

We upgraded the system to a captive-air pressure tank, where the water and air are separated by a heavy-duty butyl rubber diaphragm. This eliminates the old air-charging setup and provides a simpler, cleaner system with less plumbing to maintain.

This week we repaired two pumps from the same well. The 40 HP motor had failed, but we were able to reuse the existing pump and get it back in service. The pump is set on 8” Certa-Lok drop pipe with custom-made epoxy-coated Certa-Lok iron ni***es to help combat electrolysis.

The same well also has a smaller domestic pump set inside the column, allowing one system to handle both field irrigation and water for the dairy.

Irrigation Pump: 40 HP | 460 VAC | 1,300 GPM
Domestic Pump: 2 HP | 230 VAC | 45 GPM

While we were there, we found a broken hub on the 460V electrical service that was allowing rainwater into the equipment. We repaired that as well before putting everything back into service.

From the well to the pump to the electrical, Dos Palos Well Drilling can take care of the complete system.

Today we replaced a submersible well pump for the Dos Palos Cemetery District irrigation system.

The previous 7.5 HP pump had been in service since 1997—nearly 30 years of reliable operation. We installed a new 7.5 HP, 115 GPM submersible pump and tied it into the existing variable frequency drive (VFD) system, which maintains the water supply for irrigating the cemetery grounds.

We’re grateful to help keep this important community system operating reliably for years to come.
