1. 1

   System Inspection and Flush Prep

   We isolate the unit using the service valves, connect a descaling pump and hose kit, and prepare the citric acid solution — the safest and most effective descaling agent for copper heat exchangers.

2. 2

   Full Heat Exchanger Descale

   We circulate the descaling solution through the heat exchanger for thirty to forty-five minutes, dissolving mineral deposits from the internal passages and restoring full heat-transfer capacity.

3. 3

   Filter, Sensor, and Combustion Check

   We clean the inlet filter screen, test the flow sensor response, inspect gas burner performance or electric element resistance, and examine venting components for blockage or deterioration.

4. 4

   Final Test and Condition Report

   We run the unit through several heating cycles, verify outlet temperature accuracy, clear any stored fault codes, and provide a written report noting anything that warrants attention before the next annual service.

Annual maintenance is where most plumbing companies cut corners because it is not glamorous work — but it is where Moreno Valley Plumbing Pros earns long-term customer loyalty. We treat the descaling process with the same rigor as a repair call, document every finding in writing, and give you an honest condition assessment rather than manufacturing urgency. Upfront, no-surprise pricing applies to every maintenance visit, and our base on Alessandro Blvd means fast arrival across all Moreno Valley ZIP codes.
