Hard Water Map

Choose your taps wisely. Think about the water quality in your area, and ask your installer for advice on which materials are best suited. Above all, go for quality. By investing in well-made taps and showers you’ll have a much easier job of keeping them pristine for years to come.

This water hardness map is a guide only. To confirm your water hardness please visit your local water authority website.

why is hard water a problem?

Hard water itself isn't necessarily a problem. In history people enjoyed the healing effects of it. For example, the mineral-rich springs in Bath are famous for those healing properties.

However, hard water can have other unwanted side-effects, especially on your taps and showers. If hard water is heated past or left to stand, the dissolved minerals in it solidify as the moisture evaporates. These solidified minerals are called limescale. Limescale will often cover taps and build up in shower heads and it can be difficult to remove.

According to water-guide.org.uk that in an average 4 person household generates up to 70kg of limescale in a single year. That is a lot of limescale to try to keep in control!

What can you do yourself to help keep the limescale at bay and your Bristan taps and showers in tip top working condition?

tips and hints for limescale free taps and showers

Cleaning taps with a microfibre cloth
The best way is prevention - make tap cleaning part of your routine. By regularly giving your taps a quick wipe with water and a microfibre cloth you’ll maintain an everyday shine, and stop any major stains from settling in.
Cleaning taps with toothbrushes
Don't throw away your old toothbrush, relegate it to cleaning duty. You may find that highly stylised taps and showers mean a collection of hard to reach nooks and crannies, but by using a toothbrush you can get into even the smallest spaces and ensure a complete clean.
Cleaning taps and showers with lemon juice
Sometimes, natural remedies are still the best solution. If you don’t fancy the idea of chemicals in your bathroom, lemon juice is a fantastic way of shifting stubborn limescale. Simply soak cotton wool in the juice and apply to the affected areas – check back in an hour and with a little rubbing you’ll find that the residue comes away easily.
