Field-record purpose

Primary and Backup Sump System Upgrade: what the project record must preserve

The sump record compares basin inflow, pump performance, switch separation, check valves, discharge, freeze protection, power reliability, battery or water-powered backup, alarms, finished-area exposure, maintenance, and a simulated safe test. This page describes Sandison's documentation method and the evidence expected for this class of work. It does not identify a customer, publish a private address, or claim that every listed step occurred at one property unless an approved image and caption state that connection explicitly. Scope, access, code, equipment, and outcome remain tied to the actual work order.

Verification standard

The completion record distinguishes the approved work from the conditions left open

Useful proof can include meter change, pressure readings, isolated fixture behavior, moisture mapping, photographs of the exposed defect, and verification that the repaired section holds under normal operation. Water failures can involve water heating, treatment, drainage, sump protection, electrical equipment, finished surfaces, public utilities, or restoration, so the confirmed leak and the resulting damage are documented separately. A useful closeout identifies the original complaint, confirmed condition, authorized work, concealed or excluded items, photographs or readings, startup or flow checks, permit or inspection status where applicable, maintenance instructions, and any follow-up assigned to Sandison, the owner, a utility, restoration contractor, manufacturer, or another licensed discipline.
