Range across supply zones: 59–113 mg/L.
Morley is supplied by Yorkshire Water, whose supply comes from a mix of upland reservoirs, rivers and boreholes; the company says water in the west comes off the moors while the east relies mostly on boreholes and groundwater. Reported hardness is 85.9 mg/L CaCO₃, ranging from 58.9 to 113.3 mg/L between supply zones. The supply here blends softer reservoir water with harder borehole or river water; at this level scale forms steadily on heating elements and taps; a dishwasher salt setting and occasional descaling are sensible.
UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).

Is tap water in Morley safe to drink?
Hardness is not a health issue; it is about limescale, taste and appliances. Mains water must meet national drinking-water standards. UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).
How many grains per gallon is Morley water?
5 gpg, equal to 4.8 °dH, 8.6 °fH or 86 mg/L calcium carbonate.
What dishwasher salt setting should I use in Morley?
For 86 mg/L (4.8 °dH) check your manufacturer's table: level 2–3.
Do I need a water softener in Morley?
Not essential; a scale inhibitor protects the heater cheaply.
