Experiencing mould and slime discoloured Water?

Discoloured water is normally short lived and can often be cleared by allowing the first incoming cold water tap to run for five minutes.

Discoloured Water: Mould and slime

Black mould or slime (also known as biofilms) is associated with tap fittings which can be removed by cleaning (both inside and outside) with a small brush (such as an old toothbrush) dipped in a mild solution of bleach. Flush the tap after cleaning to remove any bleach.

Kitchen surfaces and tiles can be wiped with a household cleaner or mild bleach solution that will kill the bacteria and fungi. It’s our experience that use of a sponge rather than a scouring pad gives best results. Always remember to check that the cleaning solution you use is suitable for the surface you will be using it on.

Biofilms can occur on any surface that regularly comes into contact with water. They’re often found in the following areas around the home:

  1. On the inside of taps (especially where the tap has a mesh-style-like insert to prevent splashing)
  2. In and around washing machine powder drawers and door seals
  3. Around the base of taps and tap fittings
  4. In drains/plugholes, in and around toilet cisterns
  5. In shower heads and on shower curtains and doors
  6. On tiles around the bathroom area and kitchen sink area

What are biofilms?

The appearance of slime in and around taps, or the staining of tiles and surfaces in kitchens and bathrooms is often due to the growth of microscopic organisms such as bacteria and fungi. Collectively, these growths are called biofilms.
Bacteria and fungi are naturally present in air, food and water and can attach themselves to damp surfaces, where they can multiply to produce a visible jelly-like growth, slime or stain in various colours (black, grey and pink).
Although not nice to look at, biofilms are considered to be a nuisance rather than a risk to health. It’s not possible to completely and permanently remove biofilms, however, it’s possible to stop them growing.

What can be done to reduce biofilms?

The bacteria and fungi that live in biofilms need water and nutrients to survive and grow. The best way to prevent growth is to improve ventilation so kitchen and bathrooms can dry quickly. It’s also important to reduce the food sources available to biofilms. These may include shampoos, soaps and general kitchen food. Keeping the areas clean and free from potential food sources will restrict growth.

Certain plumbing materials can also promote growth of biofilms, for example rubber washers in taps and some flexible hoses connected to washing machines and dishwashers. If you suspect these to be the cause of biofilms, get advice from a qualified plumbers merchant and replace them with an approved product.

If any taps where biofilm has been noticed are fed from a header tank, it’s worth investigating to check that it’s clean and correctly sealed. Biofilms attach and grow quicker on rough surfaces such as limescale. Limescale can be removed using a brush and a variety of cleaning products.

The use of water filters and softeners can also encourage biofilm growth, especially if they aren’t maintained and serviced according to the manufacturers’ instructions.
