Aquastop - what is it in a washing machine? How does the hose work?

Every washing machine is a potential source of leaks. But modern manufacturers have come up with a solution to this problem. The solution is the "Aquastop for washing machines." What is it? This device is designed to protect your apartment and your neighbors from unexpected problems like flooding.

Information about the Aquastop system

Aquastop is a device that can protect your premises from flooding that may occur due to any damage to the washing machine hose.

Reasons for washing machine leaks

The so-called inlet hose The washing structure can be damaged for a variety of reasons:

• may burst;
• the possibility of being cut by sharp corners or any objects;
• may even be damaged by your pets.

Also, don’t discount the possibility of a hose breaking off, as you are not insured against such a problem either. It costs nothing for a washing machine to flood you, a small crack in the fitting of the tube that leads to your machine would be enough for her.

Any problem will cost you a lot of time and money, which you will have to spend on repairing your own apartment and, in the worst cases, your neighbor's apartment.

Operating principle of aquastop

Aquastop is a valve with a special spring. This spring is instantly activated by the pressure drop in the tube.

For example, if the Aquastop system in your washing machine detects an unexpected leak, the water supply to your washing machine is immediately shut off. In this case, you don't even need to worry about opening or closing the valve that supplies water to the machine's inlet hose.

One of the main features of this system is a fairly thick water supply hose, which can withstand up to 70 bar, while the most basic standard water supply can only withstand 10 bar. This hose is where the familiar electromagnetic valve, which is also located in the washing machine itself.

The solenoid valve is also called a safety valve. Its normal position is closed.

Manufacturers have carefully designed the entire system. The inlet hose itself is not watertight, so water drains into a special tray. The tray contains a sensitive element that instantly closes all the valve contacts, closing the hose and thus stopping the water supply.

The Aquastop system can also shut off the water supply to the washing machine if the detergent (powder) dosage is too high or incorrectly calculated—this is another distinctive feature. This is because the foam that forms when the so-called lower tank is overfilled will leak out and overflow. These machines often have water pumping functions, but these will only be activated if the operating valve (or the emergency valve) fails to perform its function in this situation.

Types of Aquastop for washing machines

The very first Aquastop system was invented by the manufacturer Bosch back in the nineties and equipped all of its washing machines with this system.

Since then, a large number of different and varied types of valves have appeared, each with its own advantages and disadvantages:

1. The so-called instantaneous water shutoff system is capable of shutting off the water supply to the machine through the hose in one second—this is a UDI type. Externally, this element is unremarkable, resembling a standard threaded hose; it can also be attached separately. All the interesting parts are located inside the element. For this aquastop to work, it requires a sudden drop in pressure in the hose, but it won't stop small water leaks.
2. A washing machine will cost more than a standard automatic washing machine due to its pre-installed AquaStop system. These systems can be simple, typically connected to the bottom and automatically shutting off as soon as water leaves the drum, or with an automatically activated valve (located at the beginning of the water intake and equipped with an automatic system, meaning it's controlled by an electric motor) that pre-assesses any changes in the water flow. The latter types can even detect leaks in the inlet hose itself. Some HydroStop systems can be activated and controlled via radio waves (at the manufacturer's discretion).
3. One of the latest developments is the Aquastop powder system. This system uses a special hose that connects one end to the washing machine and the other to the water supply. This system is considered disposable, absorbing water using an absorbent. This is due to the double hose with empty walls—when a leak occurs, all the action occurs in that space. Thus, the leak will be fixed, and the valve will shut off the water supply. However, this option isn't particularly reliable in terms of protection; it's more likely to protect you from a few leaks.

How to install Aquastop yourself

If you purchased a washing machine without Aquastop, you can install it yourself. We'll walk you through the process step by step:

• First, you need to disconnect the washing machine from the electricity and water supply;
• Next, you need to disconnect the hose that supplies water to the structure (At the same time, you can check it and, if necessary, replace the rubber seals (shown as rings), as well as clean and flush it. filters rough cleaning);
• The sensor itself must be installed on the water supply tap and must be turned clockwise, which is important;
• Then we connect the inlet hose to the aquastop system;
• Before completing the installation, make sure everything is in good working order and secure. You can do this by slowly running water through the inlet hose. This will allow you to identify any problems and fix them.

Additional flood prevention measures

There are other ways to prevent leaks besides installing special devices in your washing machine:

• For installation of supply lines to the technological device water pipes Various materials can be used. Generally, these are metal-plastic or polypropylene, but copper and zinc-coated metal pipes are also available. The latter option has the shortest service life (up to 30 years). As for metal-plastic, it's best used only for pressure-testing models. Polypropylene has proven itself, but such pipes cannot withstand severe mechanical failure. Experts recommend avoiding aluminum faucets and fittings. High system pressure is sufficient to cause such small components to burst, which could lead to potential leaks.
• There is an option to lay a bed in your bathroom floor made of special waterproofing materialThis method will protect you and your downstairs neighbors from leaks. If done correctly and efficiently, the water will drain into the sewer system on its own. The only drawback to this method is the floor level, which will rise during installation.
• The correct and finally confident decision will be shutting off all riser valves at a time when all the owners are not at home. This is necessary in cases when your drain hose The washing machine hose is already damaged, and if water leaks through any cracks in the hose, there's a high risk of flooding at the most unexpected moment. This recommendation comes with every washing machine, but many modern consumers are so confident in the functionality of their appliance that they simply don't read the safety precautions in the manual.

The Aquastop system for washing machines is a significant breakthrough in the field of accessories for washing machines.

If you purchased a washing machine already pre-equipped aquastop system, then you don't have to worry too much about your machine breaking down and leaking, because with such a system in the washing machine design, the risk of huge financial losses gradually decreases to zero.
