Difference between domestic waterworks and domestic water pump: Which is better?
Are you undecided about choosing between a domestic waterworks and a domestic water pump? Even though the names are similar, these devices differ fundamentally in functionality and application. Below, you'll learn which device best suits your needs.
What are the differences?
The main difference lies in how the devices regulate water pressure and deliver the water:
- A domestic waterworks consists of a pump and a pressure tank, which ensures a consistent water pressure. It is more suitable when water is scarce.
- A domestic water pump doesn't have a pressure tank and is less complex in design. It delivers water directly without intermediate storage. It's the better choice when constant pressure is needed.
What is a domestic waterworks?
The domestic waterworks pumps water from a source such as a well or cistern and delivers it to a point of use in the house or garden. It consists of a pump, a pressure tank, and a pressure switch.
A domestic waterworks operates automatically, meaning the pump only starts when needed. When the required pressure is reached, the pump shuts off automatically. The pressure is not constant; rather, fluctuations occur throughout the entire pipe system. It's ideal for watering gardens, operating irrigation systems, and supplying domestic water.
Stainless steel domestic waterworks 1200 W
The WALTER 1200 W domestic water pump pumps water from cisterns or wells up to 46 m high—ideal for gardens and homes. It features a shutoff function and accessory set for safe, efficient water supply.
Areas of application in private households & gardens
The domestic waterworks is ideal for:
- Garden irrigation
- Operation of irrigation systems
- Domestic water supply
- Cleaning work in the garden
- Filling ponds
How it works
The functioning of a domestic waterworks is based on a split pressure vessel with membrane technology:
- One of the sections is filled with water while the other is under pressure.
- The membrane moves when water is drawn, triggering refilling of the reservoir. This maintains a stable system for a constant water supply in the pipe network.
Differentiation from the garden pump
Unlike a domestic waterworks , a garden pump is manually operated . It operates at full power every time the pump is started. A pump is well suited for garden irrigation because it can deliver a lot of water in a short time at a constant pressure.
Domestic waterworks have the great advantage of being automatic. They are ideal for domestic water supply and irrigation systems.
What is a domestic water pump?
The domestic water pressure pump provides instant water pressure when a tap or toilet flush is opened . This ensures that water flows without delay as soon as a tap is opened.
A domestic water pump has no pressure tank and delivers water directly without intermediate storage. The pump is controlled by an automatic on/off mechanism . This mechanism ensures that the pump only starts when needed and shuts off once the required water pressure is reached. This is ideal when constant pressure is required.
Domestic water pump 1100 W
The WALTER 1100 W automatic domestic water pump delivers constant water pressure—ideal for garden irrigation and domestic water supply. Robust, powerful, and with automatic control.
Areas of application:
Wherever constant water pressure is required, such as:
- Water supply in the house
- Garden irrigation
- Toilet flush
- Operation of irrigation systems
How it works
A domestic water pump requires no pressure tank and therefore delivers the desired water pressure immediately. It uses a pressure sensor and a pump system:
- When a tapping point is opened, the sensor detects the pressure drop and activates the pump.
- The pump delivers full pressure immediately.
- The pump transports water from the storage tank into the pipe network.
- It only switches off when the pressure has increased again after closing.
Which is better suited for which purpose?
Domestic waterworks
- For recurring, smaller water withdrawals such as from a tap
- Ideal for sucking water from wells for garden irrigation
- For cleaning work in the garden with a high-pressure cleaner
Domestic water pump
- Immediate water pressure when opening a tap, like a toilet flush
- Constant water supply without pressure fluctuations, ideal for operating a washing machine
- Ideal for operating irrigation systems such as sprinkler systems
Conclusion: For little water domestic waterworks, for constant pressure domestic water pump
If you have little water or for recurring, smaller water withdrawals, a domestic waterworks is the ideal choice as it provides a reliable water supply for household use.
However, if constant pressure is required, especially for appliances like dishwashers, washing machines, and showers, a pressure-controlled domestic water pump is a better option. The pressure-controlled domestic water pump ensures full pressure immediately upon opening a faucet, thus ensuring a constant water supply without pressure fluctuations.
In addition, a domestic water pump and a domestic waterworks contribute to environmental protection by optimizing water consumption, saving energy and making the use of water resources more efficient.
FAQ
Frequently Asked Questions
What is the difference between a domestic waterworks and a domestic water pump?
The main difference lies in the water pressure regulation and delivery: The domestic waterworks ensures consistent pressure through a tank, ideal for low water usage. The domestic water pump delivers water directly without a tank and is better at maintaining a constant pressure.
Which is better: domestic waterworks or pump?
A garden pump is sufficient for infrequent and irregular water withdrawals. A domestic waterworks offers an integrated solution with automatic pressure regulation and is a better choice for domestic use.
When do you need a domestic waterworks?
A domestic waterworks is ideal for providing additional water for household applications such as flushing toilets, running washing machines, and watering the garden. It ensures a continuous water supply, especially in areas with insufficient or seasonally fluctuating water supplies.
How does a domestic water pump work?
A domestic water pump uses a pressure sensor and a pump system to pump water from the storage tank into the mains. Unlike conventional systems, it doesn't require a pressure tank. The sensor detects the pressure drop when a faucet is opened and activates the pump. The pump only shuts off when the pressure rises again after the faucet is closed.
