Assess a fountain pump, nozzle or VFD fault against the exact mechanical and electrical baseline. HJ coordinates the appointed hydraulic and electrical parties, checks supported control and protection, approves the correction and records the agreed water-effect and fault-response tests; drive settings are not a substitute for pump diagnosis.
Conceptual planning path — not an as-built drawing or project photograph.
Tell us the fault and your location. Diagnostic attendance, repairs, parts and any travel charges are confirmed with you before work.

It sits in Fountain & Multimedia Service under Water Feature. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.
Pump/nozzle/VFD models and approved settings, symptom and level/flow observations, pipework, protection/interlocks, isolation authority and specialist test scope.

Pump/nozzle/VFD models and approved settings, symptom and level/flow observations, pipework, protection/interlocks, isolation authority and specialist test scope.
Confirm the supported pump/control, lighting and audio interfaces against the agreed hydraulic design and cue map. Assign hydraulic, water-treatment, electrical and public-space duties to the responsible parties; show commands cannot replace plant protection.
Rehearse only approved water effects, lighting and audio cues with the relevant specialists. Verify stop, unavailable-subsystem and recovery behaviour in the safe work window, without bypassing water-level, electrical or other approved protective functions.
Record equipment IDs, approved settings and cue/file versions, subsystem owners, witnessed operating and protection results, operator procedure and unresolved faults. Source-file access, treatment, parts and public-safety duties remain explicit.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Regulated or multi-discipline work proceeds only after site assessment and confirmation of the competent, qualified or appointed persons, approvals, safe isolation and responsibility required for that scope.
Installed platform, authorised ownership, parts compatibility and serviceability are checked before any repair or restoration outcome is proposed.
See related systems, how HJ installs them, and support for equipment you already have.
Use the answers as a planning boundary; site conditions and written scope remain decisive.
No. The hydraulic party must assess water level, pipework, nozzle and pump condition against the supported operating limits. Electrical and drive changes require authorised competent personnel; preserve protection and verify the approved correction.
