Fix Wall Fountain Water Flow

I have a wall-mounted commercial water fountain that has suddenly stopped delivering any water. The pump still kicks in from time to time, so I suspect the problem sits somewhere between an aging pump, clogged tubing, or a faulty sensor/solenoid, but I need a professional diagnosis rather than guesswork.

Your task is to get the unit back to a steady, reliable flow and confirm that all electrical and plumbing components are operating safely. Please bring whatever you normally use for on-site pump testing, line flushing, and electrical checks; access to the unit’s power and water supply is straightforward.

Deliverables I need from you once the visit is complete:
• Root-cause report outlining what failed and why
• Replacement or repair of the faulty part(s)
• Proof-of-function: continuous, splash-free flow for at least 30 minutes
• Short list of preventive maintenance tips for our staff

If you’ve dealt with intermittent pumps and blocked fountain lines before, you should find this a quick win. Let me know your earliest availability and any parts you might want me to pre-order so we can wrap this up in one visit.
