Water Softener Installation in Belfast: Frequently Asked Questions
Do I need a water softener?
If you live in a hard water area (above 200mg/l calcium carbonate), a water softener can prevent limescale buildup in your boiler, pipes, and appliances. Most of South East England, East Anglia, and the Midlands have hard or very hard water.
How much salt does a water softener use?
A typical household of 4 people uses around 1 block or 10kg of salt per month, costing approximately £5-£8. Salt-free conditioners use no consumables but are generally considered less effective.
Will a water softener affect my drinking water?
Softened water contains a small amount of sodium. Most plumbers will install a separate hard water drinking tap at the kitchen sink. This is recommended by most water softener manufacturers and some water companies.
How long does installation take?
A standard installation takes 2-4 hours. More complex installations involving pipework rerouting or fitting in tight spaces may take a full day.
