Filter replacement
How often should the filters in our system be replaced?
Filter replacement is recommended every 9–12 months. This period may be longer or shorter depending on how heavily the appliance is used. The annual filter set consists of the sediment, pre-carbon and alkaline/post-carbon filters.
The membrane filter, which serves as the main filter, is replaced on average every 3–4 years depending on frequency of use, and is considered separately from the annual filter set. However, membrane replacement is also priced so as not to create an extra cost burden for the user.
How will I know when to replace the filters?
The LED light on the Rainwater water purification system's tap makes it easy to keep track of when your filters need replacing. If the light is blue, your filters and your water are healthy; if it is red, you will know it is time to replace the filters.
Can I replace the filters easily?
You can replace the filters in a very short time. Simply press the button on the filter head, turn the filter and pull it out. When fitting your new filter, turn it again to seat it in its housing. You can replace all 3 filters in as little as 10–15 seconds.

When I search online, many different companies appear as Rainwater service. How can I tell which one is your service?

Warranty
What does the warranty cover?
The product guarantees that the appliance will supply healthy water for 10 years (2+8), provided the filters are replaced regularly by authorised service providers. Free service is provided for any problems you may have with the system's connection equipment.
Do all appliances have the same warranty period?
The warranty period for water purifier categories is 2+8 years, while for accessories such as mixer taps it is 2 years.
Are filters covered by the warranty?
No. Filters, which are classed as consumables, are not covered by the warranty. Like vehicle filters, air purifier filters and vacuum cleaner filters, they are renewed at regular intervals for a fee. Replacing the filters regularly maintains water quality.
Is user error covered by the warranty?
The conditions under which the warranty is valid are set out in the relevant sections of the product's user manual and warranty certificate. Unfortunately, free maintenance/repair cannot be provided for use contrary to these conditions.
Can I extend my appliance's warranty?
We do not currently offer an extended warranty.
What should I do when my appliance's warranty expires?
Rainwater will provide all types of service for products throughout their lifetime.
What do I need to do to start my appliance's warranty?
You can register your appliance by calling our support line on 444 0 420.
Water purifiers
Studies say that mains water in cities is clean. Why should I worry?
Water spends a certain amount of time between leaving the dam and reaching your home. During this time it can pick up unwanted additions. Odours and sediment can get mixed in. A Rainwater system provides extremely effective protection against this contamination.
Isn't mains water clean enough before it reaches a Rainwater water purifier?
That really depends on what you consider “enough”. It is true that water quality is good in many places. But your water may still carry various contaminants that are harmful to you and that you cannot smell or taste. Rainwater removes them and brings your water to the right, excellent level it should be.
How many filters does the system have? What is inside the filters? Are they natural? What do they do?
- 5-micron sediment filter: removes all visible dirt, rust and sand particles.
- Carbon block filter: removes 99% of chlorine and organic chemicals. It removes taste, odour and colour. By filtering the water down to 1 micron before the membrane, it increases the membrane's capacity and extends its life.
- UF membrane filter: carries out the microbiological and chemical purification of the water. It is a semi-permeable membrane filter with pores one ten-millionth of a millimetre in size. It filters water at molecular level, removing germs, bacteria, heavy metals, hardness-causing minerals and all harmful substances in the water. It makes the water healthy, soft and mineral-balanced.
- Alkaline pH ceramic filter: removes foreign substances, making the water much purer, higher-quality, healthier and more functional.
Why should I choose a stainless steel tank?
Partly due to global warming, the need to store water has become unavoidable all over the world, but it can only benefit people when done in a healthy way. The main factors that degrade water quality in tanks include harmful chemicals leaching into the water from materials in contact with it, light transmission, and pores on the surfaces in contact with the water.
The Rainwater purification system's water tank is made of stainless steel and complies with food storage standards. It is extremely resistant to corrosion and rust, and long-lasting.
Why is it important for a purification system to have certification and a water analysis report?
There are hundreds of filtration appliances on sale in Türkiye and around the world. Does the water purification system you will use at home offer guarantees of quality and health? Buying a good-quality filtration appliance only comes with international certificates and a warranty. The Rainwater water purification system carries the assurance of international Water Quality Association, NSF, FDA and CE certifications and is covered by a 10-year company warranty. Water analysis reports, in turn, should be an assurance for your health. The Rainwater water purification system has been tested in the laboratories of Hıfzıssıhha, İTÜ, ODTÜ, the Ministry of Food and Agriculture, TÜBİTAK and Düzen Norwest, and guarantees water that complies with the TS 266 standard for water intended for drinking and domestic use.
How much sodium is in water purified by Rainwater?
Thanks to Rainwater's patented system, very, very little. In any case, every litre of water purified by Rainwater contains less sodium than a slice of white bread. If your doctor recommends a low-sodium diet, Rainwater's reverse osmosis drinking water appliance reduces the total amount of sodium to almost zero and fully meets the requirements of that diet.
Before you buy
I would like to try the product before buying it. Do you send trial products?
You can try our products by visiting Rainwater demo points. For details of our demo points, you can contact our customer services or find them on rainwater.com.tr.
Will my worktop be damaged during installation? Is there an alternative to having 2 taps? Will my existing water dispenser become redundant?
When installing a water purifier, our service technicians work very carefully and carry out the installation without damaging your sink.
However, we also have alternatives for customers who do not want a connection made to their sink. We have what we call 3-way taps, fittings that let you use mains water (hot and cold) and purified water as you wish.
Integration with our hot and cold water dispensers, or with the existing water dispenser or fridge you use at home, is possible. But of course, wouldn't it be more practical to live with a sink that lets you move freely when rinsing fruit and vegetables or drawing water for tea and coffee, with water much cleaner than from a 19-litre water bottle (damacana)?
Does the product take up a lot of space?
Getting something good is never effortless. Of course it will take up some space, but certainly not as much as the space packaged water takes up in your kitchen. With our customers especially in mind, we have ensured ergonomic use with models whose filters and tank are separate. The filters measure 8.5 cm deep, 34.5 cm high and 29 cm wide, and can be placed under the plinth or in an unused cupboard under the worktop. The tank holds 8 litres, is made of stainless steel and measures 30 cm high and 26.5 cm wide. We have never had a customer with problems over where to install it.
How long does it take for the product to pay for itself?
Every family has a bottled water expense, but packaged water is used only as drinking water. With a water purifier in your kitchen, however, you will do everything (tea, coffee, cooking, washing fruit and vegetables, and so on) with this clean water, which would otherwise require at least 1 bottle of packaged water a day. That is very costly and unhealthy. As a result, water purifiers pay for themselves in 10–12 months. We should think of a water purifier as a piggy bank. Health is the best investment.
Do you offer a discount if I buy more than one appliance?
Unfortunately, we do not currently offer discounts on purchases of more than one appliance.
My product's warranty has expired and I want to buy a new one. Do you offer a discount?
You can buy a new Rainwater model at a discount to replace an old model whose warranty has expired. Discount rates are updated regularly. To confirm that your appliance is in a model group that is no longer supported and to get a discount coupon, you can call our support line on 444 0 420.
What do I need to do with my appliances if I move house?
You can take your Rainwater with you when you move. Your maintenance certificate will be valid for life, worldwide. Rainwater's international dealers will provide installation and maintenance support wherever you are.
