Water Level Tube Dedra MW041 — 15 m hose for water leveling and transfer

Dedra MW041 is a water level tube consisting of a 15 m flexible hose designed for transferring and comparing water levels across distances. The tool uses the hydrostatic principle to establish equal heights between points where optical leveling is difficult or impractical. The hose is suitable for construction, landscaping, plumbing and DIY tasks that require a simple, reliable method to measure elevation differences or transfer reference levels over irregular terrain.

Advantages

The flexible 15 m hose enables level transfer over long distances without line-of-sight, and the transparent or translucent material allows clear observation of the water column. The device is lightweight and portable, requiring no power source and minimal setup time. It provides accurate relative height comparison when used correctly and is resistant to common site conditions encountered in construction and gardening.

Suitable for

• Transferring water level between two or more points without direct visual contact
• Checking elevation differences on building sites and landscaping projects
• Aligning plumbing fixtures and verifying drain slopes
• Setting reference heights for foundations, terraces, and garden beds

Key specifications

• Hose length: 15 m
• Flexible tubing suitable for routing around obstacles
• Material: transparent or translucent hose for visible water column
• Operating principle: hydrostatic (communicating vessels)
• Portable, handheld design for manual use

How to use

Fill the hose with water, leaving a small air gap at each end if desired, and ensure there are no airlocks that could disrupt the water column. Position the hose ends at the points to be compared and wait for the water level to stabilize; the water will settle at the same height in both ends when on the same reference plane. Use a marker or reference rod to record the established level and move from point to point as required, maintaining the hose at heights that avoid kinks or trapped air.

Usage recommendations

Before measurements, purge air from the hose and avoid sharp bends to ensure accurate readings. For colder conditions, prevent freezing of the water and consider using antifreeze-safe practices if applicable. Clean and drain the hose after use to prevent sediment buildup and prolong service life.
