Domestic waterworks JSW 100 / 100l

Product detailed description

Domestic waterworks units are essential components in residential and commercial water supply systems. They are commonly used in properties where the water source is not at the same level as the point of use, such as in homes with basements, multi-storey buildings, or properties with elevated water tanks. These units ensure a steady and pressurised water supply to taps, showers, and appliances. Installers typically encounter these systems in new builds, renovations, or in properties with existing water supply challenges. The JSW 100 model is designed to handle typical domestic water supply needs with a compact footprint and reliable performance.

When installing a domestic waterworks unit, the installer must consider the layout of the building, the location of the water source, and the required pressure and flow at the point of use. The unit must be positioned to allow for proper drainage and access for maintenance. It is also important to ensure that the electrical supply is correctly sized and that the unit is protected from freezing in unheated spaces. The JSW 100 is suitable for integration into standard domestic water systems and can be used in conjunction with expansion vessels and pressure switches to maintain stable operation.

The JSW 100 has a maximum flow rate of 75 l/min and a head of 45m, making it suitable for properties requiring moderate water pressure and flow. The 230 V supply voltage is standard for single-phase domestic electrical systems. The unit's dimensions (82.5 x 89 x 50 cm) and weight (27.05 kg) must be considered when planning the installation space. The 1 m supply cable length should be factored into the electrical layout to ensure a secure and accessible connection.

Installation and connection

Installation of the JSW 100 requires a secure mounting location with access to a water supply and electrical connection. The unit should be installed on a stable, level surface to prevent vibration and ensure proper drainage. The inlet and outlet connections must be checked for compatibility with the existing pipework. A 1 m supply cable is provided, and the unit must be connected to a dedicated 230 V circuit with appropriate protection. Common installation errors include incorrect pipe sizing, which can lead to reduced flow or excessive pressure drop, and failure to provide adequate ventilation in enclosed spaces.

Compatibility and accessories

The JSW 100 is compatible with standard domestic water supply systems and can be used with expansion vessels, pressure switches, and non-return valves to enhance system stability. Additional components such as pressure gauges and filters may be required depending on the water quality and system design. Installers should ensure that all components are correctly sized and compatible with the unit's flow and pressure capabilities. No related products are specified for this model.

Technical background for designers

The JSW 100 operates as a self-priming centrifugal pump, drawing water from the source and delivering it under pressure to the distribution system. The pump's design allows it to maintain suction even when the water level in the source fluctuates. The materials used in the construction of the unit are selected for durability and resistance to corrosion, ensuring long-term performance in typical domestic water conditions. The integration of the pump into the system depends on the layout of the building and the required flow and pressure at the point of use. Factors such as pipe friction loss, elevation changes, and the number of fixtures in the system will affect the overall efficiency and service life of the unit.

Service and operation

Regular inspection of the JSW 100 is recommended to ensure continued performance. Key checkpoints include verifying the electrical connections, checking for leaks at the inlet and outlet, and ensuring that the pump is free from debris. The unit should be drained and inspected during periods of inactivity, particularly in colder climates. No specific service intervals are provided in the technical data, but any signs of reduced performance or unusual noise should prompt a detailed inspection by a qualified technician.

Frequently asked questions

Can the JSW 100 be used in a system with an expansion vessel?
Yes, the JSW 100 can be integrated with an expansion vessel to stabilise pressure and reduce pump cycling. The vessel should be sized according to the system's water volume and pressure requirements.

Is the JSW 100 suitable for use with a pressure switch?
Yes, the unit can be connected to a pressure switch to automate operation and maintain consistent pressure in the system. The switch should be set to the manufacturer's recommended pressure range.

Can the JSW 100 be installed in an unheated space?
Yes, but the unit must be protected from freezing. This can be achieved by ensuring proper insulation and, if necessary, installing a frost protection system.

What is the maximum distance between the water source and the JSW 100?
The maximum distance depends on the suction capacity of the pump and the pipe diameter. The unit is designed for typical domestic installations, but for longer distances, additional calculations should be made to ensure proper suction and flow.
