The DEK-DRAIN Hydrus Catch Pit is an ideal solution for contractors and homeowners seeking an efficient, durable surface water collection system for residential or light commercial applications. It offers a significant weight and labor advantage over traditional concrete gullies by providing a robust, high-load-resistant polypropylene structure that installs quickly and reliably. While it is highly versatile for various pipe configurations, users should ensure the surrounding ground is properly leveled to support the B125 load rating of the iron grating.

A B125 rating indicates the unit is suitable for use in driveways and areas with light vehicular traffic, capable of withstanding up to 12.5 tonnes.
Yes, the system is designed to be compatible with risers to increase the overall depth of the catch pit.
No, this unit features an integrated bell trap with a handle, eliminating the need for a separate silt bucket.
The body is constructed from high-quality, durable polypropylene reinforced with side ribs.
Yes, the unit is modular and can be fitted with solid covers for applications where water collection is not required.
Remove the iron grate and check if the bell trap is clogged with debris or silt. Clean the trap and ensure the downstream pipe is clear.
Check that the grate is seated correctly in the frame and that no debris is lodged between the iron and the polypropylene housing.
Ensure the pipe is fully inserted into the pre-cut hole and consider using a suitable external sealant if the fit is loose.
Installation should be performed on a stable, compacted sub-base to prevent settling. When connecting pipes, select the appropriate concentric knockout diameter that matches your pipe size to maintain a watertight seal. Ensure the unit is surrounded by concrete or compacted backfill to support the side ribs properly. For ongoing maintenance, periodically inspect the iron grate for cracks or shifts in position. Remove the grate and the bell trap at least twice a year to clear out organic matter, leaves, or silt to maintain optimal drainage performance. If the unit is located in a high-traffic area, inspect the grate fasteners annually.
