What is a flex hose?
A flex hose is a pressurised connection hose with threaded union ends that provides a flexible transition between two fixed connection points. It is widely used in booster pump installations between the pump and tank, tank and pipework, or pump and manifold. Its flexible construction reduces the transmission of pump vibration to pipes and the building, and tolerates minor misalignments to simplify installation.
Category contents
- Straight flex hoses: For installations where the two connections face each other.
- Elbow flex hoses: For use in angled connections without requiring a separate elbow fitting.
- Various lengths: Options such as 50, 70, 80, and 100 cm allow selection to suit the connection distance.
- 1 inch connection: The most common size, compatible with booster pump tanks and pumps.
The pressure rating stated in the product information (e.g., 10 bar) indicates the maximum working pressure at which the hose can be used safely.
Selection and installation
The hose length should be slightly longer than the distance between the two connection points; a hose fitted under tension cannot absorb vibration and puts stress on the unions. Avoid bending the hose at sharp angles or twisting it on its own axis. Because the unions are fitted with gaskets, PTFE tape is generally not required; follow the manufacturer's recommendation based on the product design. After installation, pressurise the system and check the connections for leaks.
Maintenance and replacement
Flex hoses can develop rust on the outer braid, swelling, or gasket hardening over time. When these signs appear, the hose should be replaced before it bursts. Checking the condition of flex hoses during booster pump maintenance prevents unexpected water leaks.
Frequently asked questions
Why use a flex hose?
It reduces vibration, simplifies installation, and tolerates minor alignment differences.
Which length should I choose?
Measure the distance between the connection points and choose a length that allows the hose to be fitted with a slight curve.
Can a flex hose be used with hot water?
Suitability for hot water is stated in the product information; do not use unsuitable hoses on hot water lines.
What is the advantage of an elbow model?
It eliminates the need for a separate elbow fitting in angled connections.
What should I do if the hose is leaking?
Check that the gasket is correctly seated and the union is tightened sufficiently; if the gasket is damaged, replace the hose.
What else is needed for a booster pump installation?
A five-way fitting, pressure switch, and pressure gauge are the essential components.
How often should a flex hose be replaced?
Rather than on a fixed schedule, inspect the condition of the hose; replace it without delay if rust on the braid, swelling, or cracking is found.
