## Long description

GRAF BIO-7\* DRENAŻ - UDRAŻNIANIE is a drainage and clearing solution from GRAF designed for maintaining and improving water flow in domestic and small-scale outdoor drainage systems. The product name indicates a BIO-7 formulation aimed at biodegradation or biological support for clearing and preventing blockages in drains and channels. It is intended for use where organic residues, sediment and biofilms reduce permeability and cause slow drainage.
Advantages
The GRAF BIO-7\* DRENAŻ formulation works to break down organic matter that commonly clogs drains and drainage pipes, helping to restore flow without mechanical excavation. As a product from GRAF, it is developed for compatibility with typical household and garden drainage materials and installations. Its biological approach reduces reliance on harsh chemicals and can support longer periods between manual cleanings.
Suitable for
Clearing slow or partially blocked surface drains and channel drains
Maintaining garden and yard drainage systems
Preventive treatment of small-diameter drainage pipes
Removing organic residues, biofilm and sediment build-up in non-pressurized drains
Key specifications
Application type: biological/enzymatic drain treatment for clearing and maintenance
Intended use environments: domestic outdoor drains, garden channels, small drainage pipes
Effect target: organic deposits, biofilm, sediment causing reduced flow
Compatibility: suitable for commonly used drainage materials (plastic, concrete, metal) in non-pressurized systems
How to use
Apply GRAF BIO-7\* DRENAŻ according to the manufacturer's instructions for dosage and contact time. Typically, the product is introduced into the affected drain or channel and allowed sufficient dwell time for biological agents to act on organic deposits. For best results, remove coarse debris and excess standing water before application. Repeat treatments may be necessary depending on the degree of blockage and environmental conditions.
Usage recommendations
Use personal protective equipment if specified by the product label, avoid mixing with strong chemical cleaners, and store the product in a cool, dry place away from direct sunlight. For persistent or severe blockages, combine biological treatment with mechanical cleaning or consult a drainage specialist.
