How Hard Water Affects Your Plumbing in Norwich and Norfolk
Norfolk has some of the hardest water in England. Here's what that means for your pipes, boiler, and appliances.
How hard is Norfolk water?
Norfolk water is classified as hard to very hard — typically 200–320 mg/L calcium carbonate depending on location. This is among the highest in England. The chalky aquifer beneath Norfolk is the cause.
What hard water does to your pipes and taps
Limescale builds up inside pipe walls, reducing bore diameter and water pressure over years. Shower heads become blocked, mixer taps stiffen, and appliance valves can seize.
Scale in kettles and appliances
The white residue in kettles, shower heads, and taps is limescale. In washing machines and dishwashers, it reduces efficiency and eventually causes pump and valve failure.
What you can do
A whole-house water softener is the most comprehensive solution. Magnetic scale inhibitors on the heating system feed pipe are a lower-cost alternative. We fit both — ask at your next service appointment.
Our recommendation
For properties in hard water areas, we recommend descaling shower heads and taps annually, fitting a magnetic system filter, and considering a whole-house softener if limescale is causing repeated blockages.
