What size water softener do I need in LA6?
For a typical 4-person home at 51 ppm, a 24,000 grain softener is a sensible size. It would regenerate roughly every 52.5 days. Larger households or higher daily use need a bigger unit. These figures are conservative estimates.
How much does it cost to run a water softener in LA6?
At 51 ppm, expect to use about 10 kg of salt a year, costing roughly £3–£5/year. Water is soft to moderate, so limescale and soap costs are low and a softener rarely pays back.
