The HWA 4400 INOX Plus automatic water system from T.I.P. The top performance data are particularly impressive. For this reason, it also deserves second place in our comparison - even though it apparently does not integrate a pre-filter or a non-return valve.

Purchase criteria
Delivery rate
The most important criterion is the maximum delivery rate. The following applies: The more consumers you want to connect and the greater the height difference that the pump has to deal with during operation, the higher the value should be. Example: If you want to couple four or more consumers to the domestic water system, you need a device with a delivery rate of at least 3,000 liters per hour. With a eye you should also look at the engine power - it affects the flow rate.
Delivery head
Especially when the height difference to be managed by the pump is relatively large, the motor output should be as high as possible so that the delivery rate also remains in a good range. Basically, of course, you have to make sure that the delivery height of the water machine specified by the manufacturer is sufficient for your needs. In this context, it is advisable to also read customer reviews in order to get a practical impression of whether the manufacturer's information is correct or a little exaggerated.
Suction lift
The suction head - not to be confused with the delivery head - is another important point. It indicates the depth from which the automatic domestic water system can pump the water. Usually the value is seven or eight meters. However, there are also machines with a lower or higher suction height. You just have to know what you need and it is usually very easy to choose.
pump
The pump acts as the heart (piece) of the water dispenser. A lot is demanded of it, after all, it should be as powerful as possible on the one hand, but also, of course, be energy-efficient on the other. Find out what type of pump it is in each case and what properties the variant has. There are machines with a single or multi-stage pump. A multi-stage pump is more durable and at the same time quieter, but because of these advantages it is logically more expensive.
mobility
If you do not want to place your new automatic domestic water system in a permanent place in the house or garden, but every now and then want to use different places, the device should bring a certain mobility, so ´compact, handy and not excessive being heavy. Pay attention to the rubberized feet for a safe stand and an ergonomic handle for comfortable transport.
Weather resistance
What about the weather resistance of the water dispenser? If he is to spend the whole year outdoors, a high degree of protection is essential for stable water tightness. In addition, for versions with a digital display, a user-friendly designed display is important, which you can still read easily even in intense sun.
Additional functions
Pre-filter: A pre-filter on the automatic domestic water system catches coarse dirt particles and ensures trouble-free operation. If it is not part of the scope of delivery, you can retrofit it.
Dry run protection: If you want to transport collected rainwater, there is no way around buying a water dispenser with dry run protection. Otherwise the pump would continue to run even if the Rain barrel or the cistern would be empty, which could damage the device.
check valve: A check valve on the suction connection makes a major contribution to keeping the suction line tight. It ensures that the domestic or drinking water only flows in the desired direction and not (also) back.

frequently asked Questions
What is a water dispenser?
A water machine, often also called a domestic water machine, is a special pump that transports service or drinking water from a well or a cistern from A to B. Once the device is permanently connected to consumers, it switches itself on as soon as there is a need for water, for example when you turn on the tap.
How does a domestic water system work?
The main feature of the automatic domestic water system is that it works fully automatically. This means that it starts pumping immediately when you activate the water consumption. As soon as you stop consumption, the machine also stops pumping. In this sense, the effort for you with a water machine is less than with a conventional garden pump.
What is the difference between a domestic water system and a domestic water system?
House water machine and Domestic waterworks are often mistaken for one and the same device, but there are clear differences: the domestic waterworks has a pressure vessel, whereas the domestic water automat does not. That's why the Water dispenser do not save a print. If you often have to withdraw rather small amounts of water, a domestic waterworks is preferable. For watering the garden with an irrigation system, on the other hand, a house water automat is recommended.
