Hard Water in Peterborough

Peterborough sits in a hard water area due to the chalk and limestone geology of Cambridgeshire. This means the water contains high levels of calcium and magnesium minerals.

Effects on Your Plumbing

Hard water causes limescale build-up in pipes, boilers, and appliances. Over time this reduces efficiency, increases energy costs, and shortens the lifespan of your appliances. An annual boiler service helps catch limescale build-up before it becomes a problem.

Signs of Hard Water

Look for white chalky deposits on taps and showerheads, difficulty lathering soap, dry skin and hair, and kettle limescale. These are all indicators of hard water.

Solutions

Water softeners are the most effective solution. We install and maintain water softeners throughout Peterborough as part of our plumbing installation service. Alternatively, regular descaling of appliances and using limescale inhibitors can help manage the effects. Get in touch to discuss the right solution for your home.
