Know which kind of service you need
A tank flush and a tankless descale are different procedures. Look up the model and follow its service guidance. The best time to plan it is when an interruption will be easy to manage.
Factor in water quality and service history
Minerals can accumulate over time, especially where water is hard. Tell the technician when the equipment was last serviced and whether the water has changed color, the tank has begun making noise, or hot water output has dropped.
Book based on the equipment’s condition
If the heater has gone years without maintenance or shows signs of corrosion or leakage, have its condition assessed before assuming a flush is the right fix. For an active leak or no hot water, call for help.
