There are savings to be made if you have one of the old toilets. Of 45 million toilets in UK about 7 million are the old 13 litre type.

However for the majority have much smaller capacity.

Even if you had a 13 litre toilet and saved the claimed 6 litres every time, you would save say 1p to 1.5p a flush. With older toilets due to their design you often need a full flush to get rid of solids.

On modern toilets your savings are minimal.

Not the best internet advert I have seen!!!!!

Its not a cistern displacement device that save x number of litres per flush. it stops the water as soon as you take your hand off handle.

cistern displacement device dont work that well as you can never do a full flush.

No I appreciate that it is not something like a 'hippo'- I have read the website.

I am just disputing how much it will save, not the principle of saving water by using the device.

I am very happy with it. I did not know the number of people with this type of old toilets was so low. I dont know any one with the new modern toilets.. maybe most of the modern toilets are business.

I am installing every thing in my house to save money when the pay back is less then one year or less. I look in to solar hot water and solar power and wind power on the side of the house but the pay back is 15-20 year

I laid a 500ml plastic drink bottle in the floor of the cistern. Just removed the label and filled to the brim with cold water. I didn't bother to work out how much it will save, but it cost nothing and it is a tiny saving every flush. Makes no difference to the effectiveness. I might try standing a couple of 250ml bottles in a corner, saving 1 litre per flush in all.

Before I had a meter I had replaced my manky old taps with lever types; this makes it a doddle to turn the water on and off briefly while cleaning my teeth, and must have saved a fortune already in the two years since the meter was installed.

My downstairs neighbour asked for a meter at the same time but it was not possible, as the pipe feeds my supply; she did get a compensatory reduction in her annual bill, but it's still rather higher than mine.
