L'pure water washing equipment In my opinion, this is one of the best technologies of recent years. Furthermore, I have a feeling that several other inventions based on the pure water principle will follow. This tutorial presents everything you need to do for the preventative maintenance of pure water washing equipment. If you think we've missed anything, please let us know.
First, know your equipment

Garden hose

- First, connect the garden hose to the building's outdoor tap, then connect the other end to the connector. IN

100 foot hose 8 or 10mm diameter - Next, connect the filter hose to the connector OUT, as well as to the brush connectors.
- Finally, connect the brush to the outlet hoses (between 2 and 4 water outlets on the brush)

How to assemble thepure water washing equipment
You must use it correctly and ensure your employees know how to operate it properly. It's also essential to prepare it correctly before starting work. Otherwise, you could damage the resin and filter, or even break the equipment. Let's begin by reviewing the correct assembly. Here is the basic equipment for the EcoCart, manufactured by Hydrosphere Innovation. When you receive your equipment, you will need to install the filter at the top and the resin in the bottom tube.
Filtered
You will need to change the filter approximately once a month, or more often if you work with hard water (See the definition at the bottom of this tutorial). As it needs to be replaced very regularly, I suggest you keep a new one in your vehicle.
Resin
In general, you will change the resin at least once or twice during your window washing season. However, this also depends on the conditions in which you use your equipment. Indeed, the poorer the water quality, the more often you will need to change the resin. Is your resin changing color? Is your equipment leaving white streaks, or no longer cleaning as it should? Then it's very likely time to change the resin.
The end of the window washing season
At the end of your washing season, remove the filter and resin, then empty the water from the containers. You will then restart the equipment at the beginning of spring, when your schedule fills up with appointments.
Here are the results of minerals on different surfaces
As you can see, environmental dirt causes whitish stains, rust, and other grime. If these surfaces are never cleaned, the problem will worsen, eventually destroying them completely (through holes and decay). Furthermore, the dirt can increase if you live near highways or factories that pollute the environment.

THE TDS dissolved solids reader

TDS stands for «total dissolved solids.» Water naturally contains mineral salts. On the one hand, magnesium, potassium, calcium, and sodium are positively charged. On the other hand, bicarbonates, carbonates, nitrates, and sulfates are negatively charged.
What happens when the TDS level is high? The higher it is, the faster the resin wears down, and the more likely it is to allow minerals to pass through. However, it is precisely by removing these minerals that the pure water washing equipment makes the glass sparkling clean. This is why you must check the water quality at the equipment's outlet using a TDS meter. The result should be as close to 0 as possible.
Preventive maintenance of your pure water washing equipment

The rings
You will find several tightening rings on the handle. I suggest you check that the bushings are properly tightened on the handle. It's just a screw that can be tightened by hand.
However, the rings can sometimes break if the handle is left on the ground or from repeated handling. You can buy them individually or in sets.
The garden hose
A complete garden equipment kit usually doesn't include a garden hose. I suggest you choose a kink-resistant hose. It will cost a little more, but it will also last longer. Also, check that it isn't punctured. If it is, replace it.
The filtered water hose
If your hose is dried out, it may need to be replaced.
Washing brushes
There are several types of brushes. Here are some of their specific features.
The one that comes with the EcoCart pure water washing equipment, the Hydrosphere Innovation brush with rounded tip and equipped with 4 jets 
Hydrosphere Innovation hybrid brushis made of nylon. The outer part is soft, exposed nylon thread, the black threads, inside the brush you will also find stiffer, shorter nylon threads (the white ones). These are also found on both ends of the brush, giving you even more flexibility.
There Hydrosphère Innovation hybrid boar bristle brush is one of the best in my opinion. It is not harsh at all, but its mechanical action is greater. You will appreciate it on vehicle coatings or other shiny surfaces.
Another stiffer brush is the Streamline Hi-Lo Radius brush from the same manufacturer. Its special feature is that it has up to 6 jets and is more rigid.
STREAMLINE Brush 25 or 35 cm 10 or 14 in RadiusOf course, there are plenty of other brushes available, I have chosen to include the most popular ones in this product range, Hydrosphere Innovation.

You might also need a slightly more abrasive attachment for more problematic areas, The set abrasive pad adapter will be appreciated at this level
Brush maintenance
Cleaning brushes isn't very difficult. Simply rinse them to remove any trapped dirt. If your brush has picked up something sticky, like tar, use a mild degreaser (dish soap). Then rinse thoroughly.
THE manometer, pressure and pump

THE manometer This gauge indicates the pressure of the filtration system. This pressure can depend, among other things, on the water pressure in your city. Indeed, some cities have very low water pressure. In this case, you could solve the problem by adding a pump.
Transportation and storage of equipment.
During the winter, you cannot use the equipment outdoors below 5 degrees Celsius. However, you can use it without any problem for washing indoors, provided there are no electrical hazards nearby.

Hard water is water rich in dissolved salts, especially calcium and magnesium. Conversely, water low in calcium and magnesium is called soft water. Contrary to popular belief, hard water is not bad for your health. In fact, its mineral content depends on the rocks the water has passed through.
Water hardness is measured in French degrees (°f). Water is considered soft between 0 and 18 °f, semi-hard between 18 and 30 °f, and hard above 30 °f. Furthermore, the whitish limescale deposit that appears when water is heated is a sign of hardness. (Source : Le Figaro)
