Small Flush, Big Impact:

3-Litre Movement for a Thriving Planet!

– Guaranteed Savings – Made in the UK – Fast Delivery


See how much you can save!

An average flush takes about SIX litres of fresh water and shockingly, toilets account for 30% of all water consumption in a typical UK household. (Source: Waterwise).

But with the Flush and Save Toilet Valve, this volume can be reduced – significantly.

That’s because this water-saving valve can cut the water consumption of a modern, dual-flush toilet by 50% (even more for toilets made pre-2001). So instead of needing six litres per flush, you’ll only need three. And when your toilet uses 50% less water, your water bill will reduce too.

Benefits of Flush and Save Toilet Valve

Easy to install

The valve is so quick and easy to install, even a DIY enthusiast could do it.

No maintenance

No regular upkeep is required. In addition, the valve has a lifespan of 25+ years

Save more water

The Flush and Save valve CAN save water in any aged toilet – even modern dual-flush cisterns. Plus, the valve saves THREE litres per flush (not just one) – and the water savings are even greater for pre-2001 toilets.

Ensure your toilet flushes clean – every time!

When you reduce the flush volume, it’s not uncommon for a toilet to NOT flush clean. In turn, you need to flush again (and so use MORE water, not less). This does not happen when you fit a Flush and Save valve. That’s because the patented one-way, non-return valve opens so waste can leave, then immediately shuts to prevent the backflow of effluent into the toilet.

Avoid backflow

With a reduced flushing force, there’s a greater risk that toilet waste may not move far enough down the waste pipe. In turn, this presents a backflow risk (especially when water levels become unusually high). This does not happen with the Flush and Save valve. That’s because the non-return valve keeps any effluent safely in the waste and away from property.

About Flush and Save Toilet Valve

Mark Jones is the inventor of the brand new Flush and Save Toilet Valve.

These water-saving valves are designed to save water and save you money, whilst helping to save the planet at the same time.

On discovering that the average amount of water used to flush a toilet is six litres, Mark couldn’t help but think that this is an unnecessary amount: we’re literally throwing money down the toilet! He decided to see if there was a way that he could make my flush more economical – could he save water and save money at the same time?

Mark initially tested what would happen when simply reducing the amount of water used to flush a toilet from the normal six litres down to three litres. The results weren’t great: the toilet flush was not as effective and waste would be left in the toilet after flushing.

Next, he tested a reduced flush again, this time after fitting the Flush and Save valve to his toilets. This time, the results were totally unexpected.

Having fitted the valve to all three toilets in my house, Mark calculated the amount of water used by monitoring the number of times toilets were flushed. The toilets have flushed a total of 18 times in 24 hours. With a six litre flush, this would mean a total of 108 litres of water was used over a 24 hour period in his house from flushing toilets alone. Having fitted the Flush and Save valve, Mark was able to save water – 54 litres to be precise – thereby reducing the costs associated with flushing my toilet by 50%. In addition, the Flush and Save valve provided a much cleaner, more controlled flush, leaving no trace of waste in the toilet – no different to a six-litre flush! Using the Flush and Save valve is not only a great way to save water and save money but also to conserve energy.

Just think – every time you flush your toilet you are flushing clean drinking water away!

It is estimated that in the USA, for instance, $5 billion dollars worth of clean drinking water per year is used flushing toilets. This story is repeated worldwide, but by using the Flush and Save valve, the energy, water and money can be put to far better use to help our planet.


Please follow the 7 simple steps below to install your Flush and Save Toilet Valve.


Remove the toilet pan, this can be done by a competent DIY enthusiast or by your local plumber. Further information on how to do this is widely available on the internet.


Remove the toilet pan connector from the back of your toilet, (the toilet pan connector is approximately 4in. in diameter, white in colour with a black rubber sealing ring)


Remove the black rubber sealing ring from the existing pan connector or your new pan connector.


Remove the Flush & Save valve from its packaging and push it onto the pan connector. On the lid of the valve you will find the word ‘top,’ this is to be fitted to the pan connector so the lid opens in an upwards fashion to allow full discharge when the toilet is flushed. Always ensure the lid opens upwards when using a horizontal pan connecter.


When fitting to a vertical pan connector ensure the lid will open working with the flow of any bends.


Re-fit the toilet as you would normally, the Flush & Save water-saving valve will seal all pipes just like a standard non protected pan connector.


The final step is to adjust the amount of water your toilet uses each time it flushes. This is quite a straightforward process and information on how to do this will be supplied with the product.

Frequently Asked Questions

Below are the most common questions asked about the Flush & Save Water device.

How does this valve save me money?

Fitting the flush and save will allow you to reduce the water needed to flush your toilet.

Where does the valve fit?

The valve fits onto a 110mm toilet pan connector on a P-trap toilet and inserts into a 110mm pipe located on the floor of an S-trap toilet.

Has the Watersave valve been tested?

Yes, the valve has been WRAS tested Trace and volume tests were carried out that the toilet flushes more uniformly and cleaner flushing 2.5 to 3 litres of water.

What is the difference between a P-trap toilet and an S-trap toilet?

A P-trap toilet will discharge waste out of the back of a toilet and an S-trap toilet will discharge through the bottom of the toilet through the floor.

What would happen if toilet waste was to get into the pin and spring, could this cause damage to the valve?

The design of the valve and the position that the valve is fitted makes it impossible for waste to get into the components so this will never happen.

How many litres of water can I save on each flush?

The standard flush in new toilets is 6 litres but older toilets can be as much as 13 litres. On the new standard toilet fitting the flush and save will be a saving of 3 litres. Fitting to a toilet that flushes at 13 litres will save a massive 10 litres of water.

I see the flush and save has a metal pin and spring - can this rust?

The pin and spring are made from marine stainless steel – the same steel used in the salty sea. It is guaranteed never to rust.

Will the flush and save water saving device cause a blockage?

No, the flush and save valve has been tested in backflow situations by a British government test agency and passed all tests.

What are the benefits of fitting the valve?

The valve will save on increasing water costs, it is environmentally friendly because reducing the amount of sewage sent back to treatment plants means sewage can be delt with a lot easier which reduces the need to flush sewage into our sea and costal lines and rivers.

What size does the flush and save valve come in?

The flush and save valve comes in 4 inches or 110mm and will fit all toilet pan connectors.

What is the life span of the flush and save valve?

The valve has been tested and shown to have a lifespan of in excess of 30 years.

Will the valve cause any blockage?

The valves have been scientifically tested against blockage and passed all tests and no restriction or blockage was caused by fitting the valve.

What if I have a dual flush toilet?

Duel flush toilets are meant to reduce the flush but small confusing buttons make them hard to use and are often flushed at the full amount of 6 litres .

The valves have metal parts on them, what happens if they rust?

The valves are fitted with a pin and spring which are made from marine grade 316 stainless steel, this material is used in the sea and it is not possible for this material to corrode.

How do I know how much water is being flushed and that I am actually saving water?

When the Watersave valve is fitted you will also receive fitting instructions on how to reduce the amount of water in your toilet cistern, all toilet cisterns have a 6 litre mark inside them , by reducing the amount of water by half means you can only ever flush 2.5 to 3 litres of water.

What would happen if the spring breaks?

The spring is scientifically made and has been tested to flush over 20 million flushes and re-tested scientifically with no strain on the spring which is why we give a lifetime guarantee with the product.

If you reduce the amount of water then how can waste be flushed away?

This is a problem for dual flush toilets, reducing the water sometimes means you have to flush 2 or 3 times to clear the toilet, by fitting a Watersave valve, you can reduce the flush by half and the waste is taken away the first time, this is because it causes a scientific reaction mixing air water and gives a toilet a more uniform flush while the air cleans the toilet mixed with water.

How does the flush and save valve work?

Under normal conditions when you reduce the number of litres used to flush a toilet the waste will not travel very far and has the tendency to backflow into the toilet. By fitting the flush and save valve the backflow problem is eliminated leaving you with a clean fresh toilet after every flush.

Is it a legal requirement to use the valve?

It is not a legal requirement to fit a valve but it is a legal requirement to reduce water usage where possible and it is the responsibility of all to protect the water for generations to come.
