Water level (hose) Topex 25 m model 29C873

Topex water level with hose, model 29C873, provides a 25 m transparent flexible hose that uses the principle of communicating vessels to transfer and compare liquid levels over a distance. This mechanical water level is intended for tasks that require establishing equal heights without electronic equipment. The product is portable, easy to set up and suitable for use in construction, landscaping, drainage inspection and general DIY site layout.

Advantages

The 25 m clear hose allows visual monitoring of the liquid column and makes it possible to measure level differences across walls, trenches or uneven terrain. The device requires no power source and is resistant to electromagnetic interference, making it reliable in locations where electronic instruments may fail or be impractical. Its simple construction reduces maintenance needs and allows rapid deployment by one person.

Suitable for

• Transferring and matching levels on construction sites
• Checking drainage slopes and sewer gradients
• Garden and landscape grading
• Interior renovation and leveling across rooms
• DIY projects requiring height reference over distance

Key specifications

• Hose length: 25 m
• Hose material: transparent flexible tubing for visual observation
• Operating principle: communicating vessels (liquid column equalization)
• Typical fluid: water or other clear, low-viscosity liquids
• Portability: lightweight and rollable for transport

How to use

Fill the hose with water, ensuring that air pockets are removed so the liquid column is continuous. Place each hose end at the points where the level is to be compared and allow the water to settle until both columns stabilise. Use a fixed reference on each container or mark the water level on a vertical surface to record equal heights. Reposition one end as needed to transfer the reference height to other locations.

Usage recommendations

Use clean water or a clear, low-viscosity fluid and avoid colored or particulate-filled liquids that can obscure the column. Protect the hose from sharp edges and extreme temperatures to extend service life. For improved accuracy, perform measurements when the fluid is still and avoid moving the hose during settling.
