Water in Bristol
- Bristol has hard water, drawn substantially from Mendip limestone sources, typically in the 200 to 300 mg/l CaCO₃ range.
- This surprises people who assume the whole South West is soft. Devon and Cornwall are soft; Bristol is not, and the boundary is sharp. A recommendation that suits Exeter may be entirely wrong here.
- Water supply in the Bristol area is split between Bristol Water and Wessex Water depending on where exactly you are, though both areas are hard.
- The city has a large and well-established independent coffee scene, which makes commercial filtration and scale protection an unusually visible local trade rather than a niche one.
- Bristol's Georgian and Victorian housing in areas like Clifton and Montpelier often has limited under-sink space and original pipework, and installers here routinely quote for the awkward job rather than the standard one.
You have hard water — scale protection is worth having.
The World Health Organization notes that water at 200 mg/l or above will produce scale, and that is where this band begins. At this level limescale is a recurring cost rather than an occasional nuisance, and many boiler manufacturers require scale protection to keep the warranty valid. A softener is worth costing out properly.
