The Acqua Brevetti MiniDUE ½″ Liquid Water Softener is a compact volumetric proportional mechanical dosing pump water softening system designed to fit onto ½″' (15mm copper or speedfit) pipes. The system simply fits onto the rising main pipe or any pipe supplying a particular device, such as a boiler.

The MiniDUE adds the precise dosage of AcquaSIL 2/15® Liquid to water. AcquaSIL is a 100% safe, food grade polyphosphate used specifically for the treatment of drinking water.  MiniDUE provides limescale prevention and corrosion prevention within the systems such as boilers, heaters, showers, taps, radiators, coffee machines, all plumbing fixtures and so on.

The MineDUE is a great alternative to a water softener due to it being very easy to install and to maintain as replacing the pouches is very simple and quick. The system takes up very little space compared to a traditional softener as well and the cost of maintenance is lower too.

The MiniDue is an eco-friendly alternative to a water softener as no water is wasted; as softeners uses thousands of litres every month to regenerate the resin - there is no need with this innovative and space saving device. It also uses no electricity and overall the system is a great innovation in the water treatment industry.

How Does MiniDUE Work

MiniDUE is a self-priming mechanical volumetric pump that is operated by a turbine which in turn transmits the movement to a special cam shaft that enables the liquid to rise from the refil pouch to the injection valve, where it is injected a small amount of AcquaSIL 2/15®  Liquid into the water as it passes through the pipe. The liquid comes in pouches (sold in 250gram and 1000gram variants) that clip onto the system, which makes changing them very easy. The system comes with a remote installation kit, a 250gram refill, an installation manual and a warranty form.

MiniDUE is available as standard with ½″ Male connections.and can be installed on a horizontal or vertical pipe by simply adjusting the orientation of the connection block. For whole house protection you can use our larger refill pouch of 1000gram which provides up to 44 cubic meters of dosage (44,000 litres) from a single pouch.

Because MiniDUE uses a liquid solution we guarantee a sludge free operation. MiniDUE is fully compliant with European Approval EU 98/83/CE for use with drinking water. and is approved by the Italian water quality approval board under DM, no. 174, 06.04.04. The Use of AcquaSIL and specifically the use of Polyphosphates is covered by the standard UNI 8065, part 5.4.1 which indicates the use of polyphosphates for the treatment of scale deposits and corrosion.

FREQUENTLY ASKED QUESTIONS:

What is the advantage of MiniDUE?
MiniDUE is a patented device which exclusively uses a liquid 100% food grade polyphosphate designed to prevent limescale and also over time provide a de-scaling action for already encrusted surfaces.Because MiniDUE uses a liquid it 100% guarantees no sludge build up or clogging often found when using granules or powder. MiniDUE is very compact and requires no power supply. MiniDUE uses vacuum packed refill pouches which use a simple twist bayonet style fitting. Our largest refill pouch of 1000gram will provide up to 42 cubic meters of dosage, typically up to 1 years supply in a typical household.

Do I need a separate (non-treated) drinking supply?
No. this is only required when a water softener is installed which use salts. Or if other dosing systems are installed which cannot guarantee the dosage amount. MiniDUE provides 100% accurate, metered dosage of food grade polyphosphate liquid solution with is 100% safe for drinkable water

What is AcquaSIL?
AcquaSIL is our liquid polyphosphate anti limescale solution used exclusively in the MiniDUE to prevent limescale and corrosion. It is a 100% food grade liquid solution which allows a guaranteed metered dosage and delivers 100% drinkable water whilst stopping limescale build up. Polyphosphates have for years been one of the only trusted ways in which to treat and prevent limescale build up. In fact Polyphosphate is often found in many foods currently available.

What does AcquaSIL do to the water?
AcquaSIL , when released in an accurate measured dosage into the water effectively coats the mineral ions preventing them from forming on surfaces and allowing them to travel through the system. The systems has no effect of the soap effect of the water, like a salt based system does.

Will MiniDUE protect my boiler?
MiniDUE has been designed to be installed on the mains water feed directly into the boiler to provide 100% protection against limescale build up. MiniDUE also provides corrosion protection within the central heating boiler. As MiniDUE exclusively uses a liquid to provide protection, MiniDUE guarantees that no sludge or residue build up will occur thus ensuring your boiler operates at maximum efficiency. The Minidue is designed to work with water temperature of 60-65°C so is suitable for use with any domestic boiler system including Megaflow. The liquid loses its efficacy above stored water temperatures of 65°C.

Is AcquaSIL safe?
Yes. AcquaSIL and polyphosphates are classed as a ‘food grade’ additive which conform to European Standards EN1208 and World Health Organisation standards as a safe additive to drinking water.

Does it smell?
No. AcquaSIL is odourless.

Can I taste AcquaSIL?
No. AcquaSIL is a tasteless liquid.

Will it discolour my clothes?
No. AcquaSIL will not affect fabrics or finished surfaces.

When does the easy fit refill pouch need to be replaced?
When the vacuum packed easy fit refill pouch is empty, simply untwist the old used pouch and twist on a new pouch. There is no need to isolate the water supply and because we use disposable refill pouches there is no need to come into contact with any of the AcquaSIL liquid. Our refill pouches are designed to be replaced easily by you with minimum fuss. MiniDUE uses a patented system for 100% accurate and metered dose of the AcquaSIL liquid. The amount of AcquaSIL that enters the system is 100% guaranteed regardless of the volume or flow rate of the water. MiniDUE guarantees no over dose or under dose of the liquid due to the proportionate method of dosage. It’s easier than changing a light bulb. Each starter pack comes complete a 250gram refill pouch which typically will treat up to 11000 litres of water. We also offer a 1000gram pouch which will typically treat up to 44000 litres of water.

Does MiniDUE need maintenance?
Depending on the refill pouch used, a 1000gr refill pouch will typically last 12 months in an average household. MiniDUE requires no other maintenance.

Does heat affect the MiniDUE?
No. MiniDUE and the AcquaSIL is un affected by higher ambient temperature and has in fact been designed so the unit can if required be installed within the boiler casing where space permits.

Do I need a professional plumber to install MiniDUE?
Fitting the MiniDUE does require a basic competency level of plumbing skills and equipment. However, we would always recommend using a professional plumber.

Where can I buy MiniDUE and the easy fit vacuum packed refill pouches?
MiniDUE is available through all good independent plumbers merchants or direct from ourselves.

    Spent a long time looking at water softeners..expensive when you add in cost of unit, salt, electricity and extra water used daily so this was such a great alternative and I am so pleased with it..so easy to fit and change bags. Just finished first bag which came with unit and very economical, think the new 1000 bag will last a year for £30!! Nothing to complain about very happy with the reduction of timescale around the house.Thank you

    This is really neat and a great alternative to bulky salt based softeners. It took my plumber some effort to put it in but it takes up a tiny space beneath the sink.
    I've only had it a few weeks but have noticed that my shower screen is clear and my kettle isn't furring up. It doesn't take away all the limescale but cleaning taps and the sink is much, much easier and my house doesn't stink of vinegar (which I was using to clean these) now - a quick wipe and the limescale has gone. We live in a very hard water area and I was being driven mad by the constant white sheen over everything. The bag of liquid also seems to last a long time - the little one included with the device is still quite full and we use a lot of water. Overall, very pleased with the result and the convenience for the price. Glad I took the plunge.

    Simple to fit and seems to be working Ok. It is a bit difficult to say more, as I have noticed only a small change in the volume of the bag of softener.
    My only downer is the very high cost of the unit.

    Installed as specified by my plumber, have been running with it for about 4 months and have noticed very little, if any, difference in my water hardness. The lime scale is still a problem in my bathroom and that was the only reason to get this product. I have just swapped to a larger pack so will keep monitoring but as of yet not convinced this works as claimed/advertised.

    My plumber fitted this in no time at all and I'm delighted with the results! We ripped out our old softener as it was around 10 years old and are now pleased that there is no waste water or heavy salt bags to contend with. Great advice and service from Mark in the office. I would highly recommend the product and the service and will be back for some liquid in 6 months or so! Many thanks, Lindsay Black.

    Really impressed with this little wonder. Living in a very hard water area we were sick of the unsightly limescale build up on our showers and taps. We'd almost given up on softening as being too expensive and also too bulky to fit in our kitchen.

    The MiniDUE has been a God send. It's tiny and was so easy to fit in our small under sink cupboard.

    I'll admit that it's size and cost did make us wonder whether it could perform as well as bigger, more costly systems. However, it was so affordable it was easy to justify just giving it a try.

    Thankfully we haven't been disappointed. We've been running it for a month now and so far we've seen no build up of limescale on our taps and showers.

    Fabulous little device, really pleased with it!

    After having a salt softener for several years, I searched for a non salt alternative and found Osmio. They gave me very good advice and service and recommended the liquid doser system, which to be honest I was very reluctant about at first but now its been installed and used for 2 months, I have to say I am absolutely delighted with the results. There is no build of of limescale and the system takes up very little space and the best thing is that the liquid bags are so small which is a huge relief from the 25kg bags we had before. I have also saved money and I would have n hesitation to recommend this product and Osmio for their advice, service and support. Many thanks, Brian Gibbons.
