With the water dispenser HWA 4400 INOX Plus from T.I.P. Above all, the top performance data inspires. 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. You can of course retrofit both elements, but the price is relatively high for the lack of these extras. However, the device should convince in terms of quality and functionality. This is what most Amazon reviews suggest.

For relatively little money you get a device that has extremely solid performance features and comes with a pre-filter, dry-run protection and non-return valve. The majority of Amazon reviewers define this machine as a compact and "very good garden pump". But it should be pretty loud.
Purchase Criteria
conveying capacity
The most important criterion is the maximum flow rate. The following applies: The more consumers you want to connect and the greater the difference in height that the pump has to cope with during operation, the higher the value should be. Example: If you want to connect four or more consumers to the domestic water pump, you need a device with a flow rate of at least 3,000 liters per hour. You should also keep an eye on the engine power - it affects the flow rate.
head
Especially when the difference in height to be managed by the pump is relatively large, the motor power should be as high as possible so that the flow rate remains within a good range. In principle, of course, you must ensure that the delivery height of the automatic water pump specified by the manufacturer is sufficient for your needs. In this context, it is advisable to also read customer reviews to get a practical impression of whether the manufacturer's information is correct or a little exaggerated.
suction lift
The suction height - not to be confused with the delivery height - is another important point. It indicates the depth from which the domestic water pump can pump the water. As a rule, 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, then the choice is usually very easy.
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 of course also be energy-efficient on the other. Find out which type of pump is involved 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 logically more expensive due to these advantages.
mobility
If you don't want to place your new automatic water pump in a fixed place in the house or garden, but want to use it in different places from time to time, the device should have a certain degree of mobility, i.e. it should be compact, handy and not overly heavy. Also pay attention to rubberized feet for a secure footing and an ergonomic handle for comfortable transport.
weather resistance
What about the weather resistance of the water dispenser? If you want to spend the whole year outdoors, a high degree of protection is essential for stable waterproofing. In addition, for versions with a digital display, it is important to have a user-friendly display that you can still read well even in intense sunlight.
Additional functions
pre-filter: A pre-filter on the domestic water system catches coarse dirt particles and promotes 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-running protection. Otherwise the pump would continue to run even if the rain barrel or cistern was empty, which could damage the device.
check valve: A non-return valve on the suction connection plays a major role in keeping the suction line tight. It ensures that the service or drinking water only flows in the desired direction and not (also) back.
youtubefrequently asked Questions
What is a water machine?
The water automat, often also called domestic water automat, 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 automat work?
The main feature of the automatic water pump is that it works fully automatically. This means that it starts pumping as soon as you activate the water consumption. As soon as you stop the consumption, the machine stops pumping too. In this sense, the effort for you with a water dispenser is less than with a conventional garden pump.
What distinguishes a domestic water pump from a domestic waterworks?
Domestic water system and domestic waterworks are often mistaken for one and the same device, but there are clear differences: the domestic waterworks has a pressure vessel, while the domestic water system does not. This is why the automatic water pump cannot store any pressure. If you often have to remove small amounts of water, a domestic waterworks is preferable. For watering the garden with an irrigation system, on the other hand, a domestic water system is recommended.
