My gadget has stopped working

Product Specific Questions
Save-a-flush
I have a toilet with a push-button, should I fit a save-a-flush?

No, we don’t recommend fitting the save-a-flush in dual-flush toilets. They are usually already flushing with an efficient volume and the save-a-flush can damage the valve mechanism in the cistern.

I have a slim-line toilet, should I fit a save-a-flush?

No, we don’t recommend fitting the save-a-flush in slim-line toilets. They are usually already flushing with an efficient volume.

How do I fit the save-a-flush?

Installing a save-a-flush into your old single flush toilet can save one litre per flush - that’s 8,760 litres per year for a family of four and up to £18 off your metered water bill.

  • Remove your toilet cistern lid.
  • Press the save-a-flush to free any trapped air that might be in the bag.
  • Flush the toilet and quickly hook the bag on the toilet cistern furthest away from all floats or flappers with the bang inside the system.
  • Replace the toilet cistern lid. Allow six hours for the save-a-flush to expand then check the mechanism and overflow are not obstructed by the bag.
How long will the save-a-flush last?

It should last for five years but we recommend checking it for signs of wear-and-tear after three years.

How long does it take for the save-a-flush to swell up when I put it in the cistern?

It usually takes up to six hours for the save-a-flush to swell up completely so check again later.

How much water will the save-a-flush save?

It will save 1.2 litres of water per flush.

Tap inserts
What kind of taps are the inserts suitable for?

The tap inserts are suitable for taps with round, threaded outlets that are 22mm or 24mm in diameter. They are not suitable for all models of taps.

What is the blue/grey plastic tool for?

The plastic tool included with the tap inserts is to help you unscrew the nozzle on the outlet of your wash basin taps.

How should I look after my tap inserts?

We recommend the tap inserts are cleaned regularly to prevent the build-up of limescale.

How do I fit the tap inserts?

Your tap insert will save one litre of water per minute. By reducing the time you run the cold tap by two minutes per day you could save 4,380 litres of water a year, or £36 per year for a family of four on a meter.

  • Place the supplied blue tool around the nozzle where the water comes out and check it fits snugly. It’s made of plastic so it won’t scratch your tap.
  • Twist anti-clockwise, until the housing unscrews. Make sure you don’t force it.
  • Remove the nozzle and carefully remove the seal (a thick rubber ring) – then put it to one side, as you’ll need it later.
  • Remove the original insert from inside the nozzle, you will need to decide which adaptor ring you’ll need – you have two black and two grey adaptors.
  • Feel with your fingers inside the tap nozzle – if it’s smooth use the black adaptor.
  • If the nozzle is too small for either adaptor you won’t need one – simply insert the aerator on its own.
  • Insert the aerator into the adaptor, if it doesn’t fit or falls out, the adaptor is the wrong way around.
  • Insert both into the tap nozzle – with the white cap facing upwards and the grey mesh facing downwards.
  • Put the rubber seal back into its original position and then screw the tap nozzle back on, using your fingers.
Kitchen swivel tap

The swivel tap is suitable for mixer taps with round, threaded outlets that are 22mm female or 24mm male in diameter. They are not suitable for all models of taps.

  • Screw the swivel tap onto your tap and tighten by hand.
Water saving showerhead
How do I know whether I need a water-saving showerhead?

If your shower already has a low flow rate you probably won’t need a water-saving showerhead. To find out, use a measuring jug and a stop watch to measure how much water is used by your shower in a five second period. If it is more than 700ml then you could save water by fitting the water-saving showerhead.

What kind of showers is the showerhead suitable for?

The showerhead can be used on power showers, pumped showers and gravity-fed showers with a good flow rate. They cannot be used on electric, fixed-head or multi-jet showers.

How will the showerhead help save water?

The flow rate through the showerhead is capped at six litres per minute. Some power showers can use up to 20 litres a minute – less efficient than having a bath. Of course the amount of water you use is also very dependant on how long you spend in the shower.

We recommend that four minutes should be enough – order your free shower timer to help remind you.

Are there any other benefits with saving water in the shower?

Yes, by saving on hot water you may also save money on your energy bills as you won’t be paying to heat as much water.

Will I still get a good shower with a water-saving showerhead?

Fitting a water-saving showerhead does not mean you will get inferior showers. The showerhead is designed to save on your water and energy bills while not compromising on the invigorating and relaxing feel of a powerful shower.

Will the showerhead fit my existing shower hose?

It should fit all existing hand-held shower hoses by their 0.5 inch standard thread connection.

I want to install a water-saving showerhead to my power shower. If the showerhead restricts the flow of water from the shower unit will there be any pressure build up?

No, the showerhead is fitted with a flow control regulator which allows normal, but restricted, flow between 1-3 bar and regulates the flow by a diaphragm as pressure is increased. It will not cause pressure build up. It is designed not to.
