Hippo the Water Saver is the simple, proven and low cost water saving device to help conserve water in household toilet cisterns. Every time a toilet is flushed the Hippo saves approximately 3 litres of water.

Hippos installed in the average home provide a saving on your metered bills of approximately £20 per annum, with a pay back on your initial investment within 8 - 12 weeks. When the toilet is flushed, the water confined within the Hippo is the volume saved.
The Hippo also has a small hole which acts as a relief valve allowing slow circulation of water to prevent stagnation and evaporation.

Will it fit my cistern?
If your toilet was installed before 1991 it will be 9 litres in volume, or more. This type of toilet will work well with a Hippo fitted and will reduce the flush volume by up to 3litres.

If your toilet was installed between 1992 to 2001, it will be 7.5 litres in volume. This type of toilet will also work well with a Hippo fitted and will reduce the flush volume by up to 2.5 litres.

If your toilet was installed after 2001, it will be 6 litres in volume (the current standard) and it should not be reduced further with any type of device whatsoever.

Are Hippo's effective in the home?

Each Hippo will save on average 3 litres of water (appoximately 33% of the cistern volume) every time a toilet is flushed. Independent research has shown Hippo will provide a 10-15% saving on total water use.

Are Hippo's effective in the workplace?

33% of your precious water supply is unnecessarily flushed down the toilet. In the workplace each employee uses the toilet about 3 times each day and over a working year this amounts to 6000 litres (6 cubic metres) of water.

What are the financial benefits?

Whether Hippo's are being bought for your home or for your workplace, the pay back period on your initial investment is between 8 - 12 weeks. Thereafter you will enjoy a regular cost saving on your bills. Hippo's installed in the average home provide a saving on your metered bills of approximately £20 per annum. In the workplace the typical cost saving will be £3 per employee/annum - that's a £3000 saving if you have 1000 employees!!

Can I put Hippo's into my cisterns?

Yes - but its more effective in older cisterns which use 9 to 12 litres per flush. Cisterns made after 1993 are designed to use less water, although Hippo is known to be highly effective in these smaller volume cisterns also. Hippo's can be adjusted in seconds to suit small volume cisterns or any cistern with an already poor flush performance.

How long will my Hippo last?

Indefinitely - Hippo's are manufactured from Polyethylene and when immersed in the confines of the toilet cistern, they are designed to last a lifetime.

Do Hippo's have a track record?

Since 1997 over 10 million Hippo's have been sold with a combined daily water saving equivalent to 22 Olympic size swimming pools!
