Water ATM Maintenance Checklist: Daily, Weekly and Monthly
Quick answer: A water ATM needs a short daily routine (clean and sanitise the nozzle and drip tray, check the water tastes right and the TDS is normal), weekly checks (flow accuracy, payment system, leaks), and monthly service (UV lamp and quartz sleeve, filters, storage tank). Replace the UV lamp about once a year even if it still lights.
Key facts
- Daily: nozzle, drip tray, TDS and taste
- Weekly: dispense 20 litres into a measure to check accuracy
- Monthly: UV sleeve, filters, tank
- A UV lamp loses strength before it stops lighting: replace yearly
