Any automatic machine must be connected to the water supply system of a house or apartment: for this, a special inlet hose for a washing machine is used. A tap must be installed between it and the system in order to quickly shut off the flow of water in emergencies or for carrying out preventive maintenance. Sometimes it becomes necessary to replace a hose that has become unusable due to a broken shell, a leak, a broken fastening nut or other important part. You have to buy a new water supply hose, and here various surprises await the user. To purchase a truly reliable product, you need to know its types, as well as the approximate cost.
How to install aquastop correctly?
You can install it yourself. To do this you need to do the following:
- Disconnect the washing machine from the power supply and water supply.
- Disconnect the hose required for water supply from the washing machine. ...
- Install the sensor on the water supply tap. ...

Here is a brief description of all the connection diagrams that we are going to introduce the reader to:
| Image | Description |
| The water tap is installed between the cams (eccentrics) and the corners or water sockets under the faucet in the bathroom. For hot water, a chrome extension is mounted, the same length as the faucet. The advantage of the scheme is the convenient and accessible location of the tap, the disadvantage is that the mixer extends 8-10 cm from the wall. |
| The tap is screwed into the thread on the rigid cold water supply in front of the flexible hose, which is responsible for connecting the on-board faucet or toilet flush cistern. The union nut of the flexible connection is connected to the external thread of the faucet. Advantages: the tap solves the problem of sealing a flexible connection with an uneven edge of a steel thread; The connection node is in most cases hidden from the view of the visitor to the room and does not spoil its design. Disadvantage: inconvenient access to the tap |
| The connection is made with clamps to a smooth steel pipe at any convenient water supply point in the apartment or even directly to the riser to the valve at the entrance to the apartment. Advantage: arbitrary location of the tap, not tied to a threaded connection. Disadvantage: violation of the integrity of the water supply system. After turning off the washing machine, the clamps will remain on the pipes. |
Examples of using
In theory, everything sounds simple, let’s look at successful and “working” examples in practice.
Three-way valve from Fornara
This faucet is made in Italy. It belongs to the category of tees, so it has three threads: for a washing machine, water supply and plumbing. The product is made of quite high quality and lasts a long time.
Croatian tees
Such three-way ball valves are made of brass and coated with chrome plating. They have standard thread sizes and three outlets. The product works for at least 20 years.
Decorative corner tap Rubinetta
This mini-model, designed specifically for washing machines, will look good as a corner valve. The tap is miniature, straight through, with high-quality chrome plated.
Angle tap ITAP
This ball angle valve has the same thread on both sides - an external half-inch thread. Used to connect any plumbing fixtures. not just washing machines. Made of brass, nickel plated.
Method 3: connecting to a direct section of water supply
The last scenario is inserting a tap into a straight section of water supply.
Materials
Required:
- Clamp with internal thread size 1/2 inch (DN 15);
Brass clamps for inserting into steel water pipes
- Ball valve with male-female threads;
Ball valve with external and internal threads
- Adapter from DN 15 thread to DN 20 thread.
Captain Obvious suggests: the adapter must have two external threads. One is screwed into the ball valve, and the union nut of the inlet hose is screwed onto the second.
Brass Pipe Thread Adapter
- Sealing material for threads.
Installation
- Turn off the cold water;
- We drill a hole with a diameter of 8-10 mm in the HVS liner;
- We clean the surface of the pipe around the hole from paint and rust;
- Install and tighten the clamp;
Tip: if the clamp does not include a rubber gasket, cut it from an old car inner tube.
- We sequentially install the ball valve and adapter, tightening the threaded connections;
- We connect the machine with the inlet hose;
- We check connections under pressure.
A special case
What to do if for some reason you cannot turn off the water (the valve on the supply line is faulty, the tap needs to be embedded in the riser, etc.)? This scenario differs from the scenario described above only in the sequence of actions and a specific tool.
- Mount a clamp on the pipe that has been cleaned of paint and rust and install a ball valve on it;
To clean the pipe, it is most convenient to use a drill with a wire brush.
- Open the faucet and drill the pipe directly through its valve;
- As soon as the wall of the supply or riser is drilled, remove the drill and turn off the tap. Further actions are no different from those described above.
Scheme of tapping into a water supply system under pressure
Important: in this case, you can drill the pipe only with a hand tool - a hand drill or a brace. A water-filled electric drill combined with a puddle on the floor will turn into a type of portable electric chair.
For work under pressure, use only hand tools

The role of the pipe in the washing machine
The pipe, like any other part in the washing machine, plays an important role in its normal functioning. Thanks to the filler pipe, water and household chemicals intended for washing enter the machine. The machine has a drain pipe that is responsible for draining the water. In cases with newer models, additional pipes are installed, which are designed to remove foam and steam. In order for the washing machine to work without interruptions, each pipe must be installed correctly and securely.
Sometimes the cause of a washing machine breakdown is a broken pipe, which can be eliminated by replacing it. But in order to increase its functioning time, preventive measures should be taken. The pipes should be cleaned periodically, just like the garbage filter, since long-term use can cause plaque to form inside it.
Installation required
Most consumers, when purchasing parts for installing a washing machine, often ask themselves why not just connect the hose directly to the water supply. What is the purpose of the crane? Of course, there is always the option to refuse to use this part, but then be mentally prepared to compensate your neighbors for losses.
For people who have already encountered such an unpleasant phenomenon as water hammer
in water supply pipes, it makes no sense to describe its consequences. This is a fairly common problem, when it occurs, the seams of metal and metal-plastic communications are completely torn. Now think about what will happen in the same situation with a soft one, which is directly connected to the water supply pipes. In a couple of seconds it will not be able to hold back the water and will rupture completely, and after a few minutes several floors of the apartment building will be flooded.
That is why it is impossible to do without a special overlapping device. An installed tap will make using the washing machine safe and convenient: plumbers recommend turning off the water after completing each wash.
Hose device
The water supply device has a simple design: the base is a polyvinyl chloride tube, which is reinforced with reinforced thread and nylon braid. The product can withstand pressure drops in the water supply system and has decent tensile strength.
There are special fittings on both ends of the device for connection to the plumbing system. The fittings are secured with plastic nuts, the length of the hose varies between 1-5 meters. If the machine is installed at a distance from the water supply system, then the connecting device is purchased in the longest possible length.
Expert advice! When connecting, do not put in much effort or use tools: do everything with your hands. Remember that fittings and nuts are made of plastic and can be easily broken.
For reliability and elimination of leaks, you can use a special tape to seal the connections. If the filling device is faulty, there is no need to repair it. Buy a new one of better quality, this will protect yourself from troubles.
Selection options
When choosing a model, pay special attention to the following aspects:
- The material
from which the faucet was made. The modern market is able to offer models made of brass or silumin. Experts do not recommend giving preference to a brass product, since silumin taps wear out quickly. - Diagram of the
water shut-off mechanism. In faucets, the most common are ball and multi-turn systems. In terms of efficiency and durability, the ball type is best. - External characteristics
of the valve. This part is designed to control the water pressure and completely shut it off. It is very important to choose a valve that is convenient for you. They may differ in size, shape and the force required to close the tap. In the event of an accident, every second will count, which is why it is so important that the surface of the valve is not slippery and fits comfortably in the hand.
Kinds
Types of inlet hoses:
- With fixed length. They are a pipe from 1 to 5 meters in length;
- In the bay. The length reaches 10 meters;
- Telescopic. Thanks to the corrugated wave, the length can be increased by stretching;
- With Aqua-stop system. A system to avoid leaks.
Method 2: connection before the flexible connection
This connection option is even simpler than the previous one. What does it need?
Materials
This:
- Faucet for washing machine . All requirements are the same as when installing it under a bathroom faucet, with the exception of the collar after the external thread: in this case it is not needed;
- Rewinding for threaded connections;
Easy to use and durable winding - Tangit Unilok thread
- Gasket for the union nut of the flexible hose or a new hose with the same length as the old one.
Reference: the trouble-free service life of flexible hoses in stainless steel braiding does not exceed 5 years. If the service life of the hoses is approaching five years, do not be lazy to replace them with new ones, without waiting for a break and flooding of the apartment.
The average service life of such eyeliner is 5 years. During this time, the rubber core loses its elasticity, so after dismantling and reinstallation the hose often leaks
Installation
Connecting the water supply to the washing machine is carried out in the following order:
- Turn off the cold water and make sure that it stops flowing to the site of the upcoming work;
- Unscrew the union nut of the flexible connection;
- Wind the thread underneath;
- Install a three-way valve;
- Replace the gasket under the union nut of the flexible hose or the entire hose;
- Connect the flexible connection and inlet hose of the washing machine;
- Turn on the water and check all pressure connections;
- Wash it.
Possible malfunctions and their elimination
The dishwasher's aqua-stop should work quickly. The first sign that the system has worked is the absence of water when the device is turned on. Many dishwasher models display an error that indicates there is no connection to a water source. If it is missing, then you should do the following procedure:
- The water supply is cut off.
- The hose is unscrewed.
- You should look inside the hose, there should be a valve located there.
- When the valve is pressed tightly against the nut, there is no gap. This moment indicates that the valve has actuated.
In some cases, there is no water supply due to a malfunction. It can be solved in several ways, which are selected depending on the design features of the system. Possible malfunctions are as follows:
- The appearance of corrosion due to the use of non-corrosion-resistant material in the manufacture of the product. It causes decreased valve patency and other problems.
- Displacement of the spring or electromagnetic element is associated with poor quality of valve manufacturing.
- The appearance of defects due to mechanical stress. In some cases, an impact can cause a change in the shape of the main element, the appearance of a crack or a dent. All this causes a decrease in the efficiency and reliability of the device.
Not all possible malfunctions can be eliminated; in some cases, the entire product must be replaced. Repair recommendations are as follows:
- The hose is being dismantled.
- The condition of the valve is viewed.
- Using a screwdriver, you can adjust the position of the spring element.
In the event of a malfunction, it is recommended to replace the entire hose. The use of high-quality products ensures high safety of the premises from leakage. When purchasing a dishwasher, you should pay attention to which Aquastop system it comes with. If it is of a mechanical type, then the reliability of the leakage protection system will be low.
Sewerage
Water drainage can be arranged:
- In a rented apartment - in the sink or bathtub. The plumbing fixture will be unsuitable for use for its intended purpose for no more than an hour and a half a day. As a bonus, you will receive a guaranteed absence of sewer blockages: hot water with powder perfectly washes away fat from the walls of sewer pipes, which is the main cause of blockages;
Not easy, but very simple: the drain is directed into the kitchen sink
- If you have a plastic prefabricated sewer comb installed in your apartment (intra-apartment sewerage distribution) - into the tee installed in its gap. Preferably - oblique, with a drain directed in the direction of movement of the drains. In this case, a volley discharge of water (for example, from a bathtub) and its simultaneous drainage by a washing machine will not lead to overflowing of the pipes;
Connecting the drain to the oblique tee
- Owners of cast iron sewers should take a closer look at siphons for sinks with an outlet for connecting the drain hose.
Connecting the drain to the siphon
The general rule is that the connection of the drain hose to the sewer must be sealed. Sealing is carried out with standard rubber cuffs or any available material (adhesive tape, polyethylene foam, etc.). Through leaky connections, fumes from sewer drains and risers will enter your apartment, and they will not smell like roses.
Sealing the connection between the drain and the sewer with a rubber cuff
Why does it leak: common causes of leaks
The most common problem that causes a leak is a weak connection to the pipe or washer; cases of simple aging and wear of the rubber gasket are not uncommon. The only correct solution is to replace this gasket.

Another possible reason could be that the hose is not in the correct position: it may be twisted or kinked. Place the hose in a natural position.
