Full details
The PBSL Group 300mm x 600mm yard gully is an essential drainage solution for homeowners and contractors seeking an efficient way to manage surface water runoff. It is designed to replace heavy, traditional concrete systems with a durable, lightweight alternative that simplifies installation while maintaining a clean aesthetic. While the unit provides excellent flow rates and easy maintenance, users should note that the gully requires proper integration with a secure surrounding, such as brickwork or a concrete slab, to ensure stability and structural longevity.

FAQs
Does this gully come with a lid or grating?
No, this product is the gully body only. It is designed to be paired with a standard iron grating suitable for your specific location.
Can I use this with 100mm pipe?
This unit is designed for 110mm drainage systems. 100mm pipe may not provide a secure, watertight seal.
How deep is the gully?
The gully measures 600mm in depth, providing excellent capacity for catching silt and preventing pipe blockages.
Is this product suitable for driveway use?
It can be used in residential driveways if properly installed with a load-bearing surround and a heavy-duty iron grating.
How often should I empty the silt bucket?
It depends on your local environment, but a quarterly check is recommended, or more frequently if there are many trees shedding leaves nearby.
Troubleshooting
Water draining very slowly
Check the silt bucket for debris buildup and clear it; if clear, check the downstream pipe for blockages.
Unpleasant odours returning
Ensure the internal trap contains water. If the gully has been dry for a long time, pour a bucket of water into it to prime the trap.
Loose grating or instability
Verify that the surrounding brickwork or concrete haunching has not cracked or eroded; repair with exterior-grade mortar.
Pros and Cons
Pros
- Lightweight design significantly reduces manual handling effort
- Easy to clean due to the removable silt bucket feature
- Universal 110mm connection fits most modern drainage setups
- Integrated trap prevents unpleasant sewer odours
- More cost-effective and easier to install than concrete alternatives
Cons
- Requires proper mortar or concrete setting for stability
- Not intended for heavy-duty vehicular traffic areas without additional reinforcement
- External grating must be purchased separately
- Depth requires significant excavation work for proper placement
Setup, Compatibility & Care
- Compatibility: Designed specifically for 110mm UPVC drainage systems. Ensure the spigot end is lubricated for a smooth, watertight connection into the socket pipe.
- Setup: Place on a level, compacted base. It is standard practice to construct a small brick chamber or concrete haunching around the top of the gully to support the weight of the iron grating and the surrounding paving materials.
- Care: Avoid pouring chemicals, oils, or heavy sediments into the gully. If the gully becomes blocked, use a drain rod through the roddable access point, but be gentle to avoid dislodging the internal trap structure.
