Test the quality of your water with our comprehensive test
Thanks to our Combined Test Kit, you can perform thorough water testing, get an insight into the quality of your drinking water and find out if it is safe to drink. Taking the sample is simple: a test kit with clear, step-by-step instructions is provided, allowing you to take the sample yourself and save both time and money. The quality of your water will then be analysed in an accredited laboratory using the latest scientific methods, and compared to the maximum values set out in the Water Supply Regulations.
The Combined Test is ideal if you want to know whether you can drink and cook with your water with confidence. To run additional testing for bacterial contamination, we recommend our Premium Test Kit.
Test your tap water - now foolproof thanks to our most popular test kit
There can be various reasons for testing your tap water. Our Combined Test is a combination of our Basic, Heavy Metals and Baby tests. You can be certain that your water doesn't contain any heavy metals, harmful salts or minerals, and is safe to drink for you and your family.
Customised advice - even after the analysis
You can conveniently retrieve your test results online after around seven days using your personal access code. But even after receiving your results, our trained IVARIO team will happily advise you on the phone or by email, because we believe that an individual interpretation of your drinking water analysis is an absolute priority.
The Combined Test is a popular, tried-and-tested IVARIO test and contains the following individual tests:
Heavy Metals Test
Baby Test (especially for water used in baby formula and consumed by pregnant women)
Tip: in addition to the Combined Test, we recommend warm water testing for legionella. Click here for more information on legionella testing.
Our Combined Test includes an analysis of your water for the following substances and values:
Lead absorption is a fundamental health concern. Due to the gradual nature of the process (constant and in low quantities), it often goes unnoticed, however lead leaves traces in the human body which are stored in the bones. Young women, pregnant women or small children need the most protection because lead absorption can affect development. In adults too, even the lowest quantities of lead can give rise to a range of health problems. A common culprit is lead piping in the home. Landlords are obligated to replace lead pipes, which have been banned since the 1970s.
Diseases have emerged that can be traced back to copper in drinking water. Therefore, water which is contaminated with copper should not be consumed by adults, infants or children. The long-term ingestion of copper through drinking water can result in considerable health problems and a risk of copper poisoning. Beware of the use of copper pipes in your house.
Excessive iron absorption has a harmful effect on humans. Other undesirable consequences include discoloration and cloudiness. An increased concentration of iron is also responsible for an unpleasant taste in the water and often leads to technical problems in the house.
Nickel can enter our drinking water through chrome-plated fittings. Nickel does not only pose a health threat to those allergic to it, but regular inhalation of water containing high levels of nickel can lead to lung cancer and tumours.
If you occasionally suffer from stomach aches and vomiting, cadmium ingestion may be to blame. In large quantities, cadmium in drinking water can also cause kidney damage and painful altered bone formation. The initial physical symptoms are vomiting, stomach aches and cramps, and long-term ingestion may lead to substantial organ damage.
Calcium naturally occurs in all water. Together with magnesium, it is crucial for water hardness because it stabilises the pH value of the water. Calcium has a positive effect on bone formation. Indeed, studies on cardiovascular health show that in regions with comparatively high levels of calcium in the water, the risk of heart disease is lower. Nevertheless, increased water hardness is accompanied by higher levels of limescale, which is not ideal, particularly for household appliances.
The total hardness of tap water is considered to be the total amount of the minerals calcium and magnesium that is released into the water. The higher the calcium and magnesium content, the harder the water. The level of hardness is measured in mg per litre. Drinking water with low levels of hardness has comparatively less flavour. Well water and tap water with high levels of hardness have health benefits thanks to the high mineral content. However, this can also lead to a faster rate of scaling in household appliances like washing machines, dishwashers or coffee machines.
Magnesium is present in all water and is one of the natural components of groundwater. The quantity of magnesium in drinking water in the UK is not high enough to have a positive effect on the body, particularly on the muscles. It is not detrimental to our health, but does contribute to water hardness along with calcium.
Electrical conductivity is an important indicator of the purity of drinking water due to the fact that pure water is inherently non-conductive.
The pH value indicates if the drinking water is acidic, neutral or alkaline. If it is acidic or alkaline, further testing is needed as this may point to contamination. Moreover, if water is acidic or alkaline, pipes may be damaged, harmful legionella can multiply and various skin diseases may arise.
Nitrite can cause cancerous diseases and is harmful for the liver and genetic makeup. Infants react particularly sensitively to nitrite in their first months of life. Ingesting nitrite can cause the red blood cells to mutate. This mutation can then lead to a lack of oxygen, because nitrite significantly impairs the transport of oxygen. A lack of oxygen can result in suffocation.
A high intake of nitrate and nitrite poses a huge health risk to humans. A condition known as methaemoglobinaemia may occur. With stomach viruses, there is a risk of nitrate being converted into nitrite.
Infants react particularly sensitively to sodium because their kidneys are not yet fully formed. An increased intake of sodium, for example through drinking water, adversely affects a child's gut flora. Even for adults, an increased intake of sodium can lead to high blood pressure or any of the cardiovascular diseases resulting from this.
An increased intake of sulphate has a laxative effect and can cause diarrhoea and vomiting. Infants and toddlers react particularly sensitively to suphate because their kidneys are not fully formed and so the excess sulphate cannot be properly excreted.

Do you need even more assurance? Test your water for legionella too!
For total protection in your household, legionella testing is essential. The legionella test is a warm water test and is carried out differently. Find more information on the legionella test here.
Also included in IVARIO's product line are the Pharmaceutical Test and Pesticide Test. Test your water for these specific contaminants.
