  • Rainwater harvesting system

    Rainwater harvesting system

    close
    A rain water harvesting system collects rain water from your roof, and a grey water reuse system collects water from sinks and baths. This water is saved in a storage tank and can be used for flushing toilets and outside taps. It is vital that these plumbing systems are kept completely separate from your drinking water supply.

  • Water heating solar panels

    Water heating solar panels

    close
    Water heating solar panels can be used to heat water. These systems are pressurised using a filling loop when they are installed. Make sure these connections are always removed to prevent backflow into your drinking water. A suitable check valve should also be installed.
  • Water storage tank

    Water storage tank

    close
    Water tanks should be covered to stop anything falling into them. This could include dirt or debris from the roof and even small animals or birds. It’s also important to make sure tanks are lagged to prevent any problems in winter.

  • Hot and cold pipes

    Hot and cold pipes

    close

    You may notice that your drinking water is sometimes cloudy, or feels warm when you first run the tap. This can be caused by cold water being heated from pipes running close together.

    For further information you can read our handy factsheets:

    Cloudy water
  • Toilet Cistern

    Toilet Cistern

    close

    Toilet cisterns need an air gap between the discharge point and the overflow. This will ensure that water from the cistern cannot get back into your drinking water.

    From time to time check that there is no water coming out of your toilet overflow. Faulty overflows let water into the toilet pan constantly. This can waste thousand of litres of water a year and cost you money.

  • Nickel

    Nickel

    close

    Some lower quality chrome plated taps and fittings have a higher Nickel content. Nickel can leach into the water, which can cause a rash or irritate the skin. When buying new taps or fittings always make sure they are approved.

     

  • Shower hoses

    Shower hoses

    close
    Make sure your shower hose can never reach the toilet bowl. If the hose is long, there should be a clip in place to make sure this can’t happen. If you need a separate shower hose near the toilet, this should always be fed from a tank.
  • Mould in shower

    Mould in shower

    close
    Mould comes from airborne spores and can appear in damp, warm environments such as in bathrooms. It is often black and slimy, but can also be red or orange.

  • Boiler

    Boiler

    close

    Your hot and cold water should never mix as the heating circuit that feeds your radiators contains unpleasant chemicals.

    When filling or re-pressurising your hot water system a temporary filling loop is used. This should always be removed afterwards, to prevent any backflow. A double check valve should also be fitted on the cold water side.

  • Lead solder

    Lead solder

    close
    Lead can be picked up from lead based soldered pipe joints, which was typically used to join copper pipes together. The use of lead solder in water systems was banned in 1987, but it’s still present in many homes. It’s not a legal requirement to remove any lead solder that was used before 1987, but it shouldn’t be used in any new plumbing work.

  • Softener

    Softener

    close

    Water softeners can add salt to your water supply, so make sure you have a non-softened tap for drinking and cooking.

    Faulty softeners can release orange resin beds into your water, so it’s important to keep them maintained and serviced regularly.

  • Lead pipes

    Lead pipes

    close
    If you live in a house built before 1970 you may have lead pipework.  This can be harmful particularly if you are pregnant or have young children.  Only cook or drink with fresh cold water from the kitchen tap – run the tap for a few minutes before use until you feel the temperature drop. If you run off any water from your taps, don’t waste it. Collect it and use it for watering houseplants or in the garden. If you think you have lead pipes, call us for more information or a free lead test on 0345 070 3445.
