The tank is as full as the score. The specks are the minerals that make water hard.

What to do about it

Hard water: compare softener quotes

At 282 mg/L a softener is the only thing that stops limescale. Filters do not soften water.

It pays for itself in most homes at this hardness, through a boiler that stays efficient and appliances that last.

This is the water that furs up kettles

Very hard on the UK scale. It is fine to drink. It is hard on boilers, showers, skin and anything that heats water, and a jug or tap filter will not change that.

Your river is the Went from Source to Hoyle Mill Stream, rated poor

The Environment Agency rated the Went from Source to Hoyle Mill Stream as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by fish, water plants and algae and dissolved oxygen. It fails the chemical test, as every river, estuary and stretch of coast in England does, because of long-lasting pollutants such as mercury, PFOS (a forever chemical) and old flame retardants.

Who supplies water in WF7?

WF7 (Wakefield) is supplied by Yorkshire Water. You can view their full profile and compliance data on our supplier page.

Is WF7 water hard or soft?

Water in WF7 (Wakefield) has a hardness of 282 mg/L CaCO3, which is classified as very hard. Hard water can cause limescale buildup. A water softener or filter jug may help.

Should I use a water filter in WF7?

With 1 contaminant above recommended levels in WF7, a water filter could help. A reverse osmosis or activated carbon filter is recommended for PFAS removal. See our filter recommendations for your area.

Are there PFAS forever chemicals in WF7 water?

The tap-water tests we hold for WF7 do not include a PFAS result. Environment Agency monitoring found PFAS in 31 river and groundwater samples from 2 sites within 10 km of WF7, the highest being PFOA at 0.0081 µg/L about 8.4 km away. These are environmental samples, not tests of tap water. The UK currently has no legal limit for PFAS in drinking water; the Drinking Water Inspectorate uses a 0.1 µg/L guideline for individual compounds. Reverse osmosis filters can reduce PFAS levels.

How clean is the river near WF7?

The Environment Agency rated the Went from Source to Hoyle Mill Stream as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by fish, water plants and algae and dissolved oxygen. It fails the chemical test, as every river, estuary and stretch of coast in England does, because of long-lasting pollutants such as mercury, PFOS (a forever chemical) and old flame retardants. This is a rating of the river, not of tap water in WF7, which is treated before it reaches homes.
