Two Major Circulation Pump Repairs in Under an Hour

October 30, 2026

Some buildings depend on one piece of equipment more than most people realize. On a commercial water-source heat pump building in San Diego County, that piece is the water circulation pump on the mechanical pad. When it started spraying water, we got the call.

The problem: a leak on the circulation pump

The building's water circulation pump had a leak. In a water-source heat pump system, that pump keeps water moving through the whole building's HVAC loop, so it needs to be fixed quickly and correctly.

Repair one: stopping the leak

Our crew made the repair on the pump line and stopped the leak.

Repair two: new coupling, shimmed and aligned

With the leak handled, we replaced the worn rubber drive coupling between the motor and the pump. Then we shimmed the pump and aligned it. Proper alignment helps the pump and motor run smoothly and protects the new coupling.

Done in under an hour

We performed two major repairs in less than an hour, and the tenants never noticed any interruption of their HVAC service.
