Full details
The Manthorpe Concealed Peep Weep Vent (G953-BU) is an essential component for masonry contractors and homeowners looking to improve cavity wall drainage. This discreet, flush-faced vent provides a robust solution for moisture management, promoting self-cleaning via a unique diamond-shaped profile. While it offers superior airflow and water egress compared to standard weep holes, users should note that precise placement during bricklaying is required to ensure the flush finish and mortar key integrity.

Extended Product Information
FAQs
What is the primary function of the G953-BU?
It provides a drainage path for moisture trapped within the cavity of a masonry wall to exit to the outside.
Will this vent keep wasps and bees out?
The 4mm opening is designed to prevent the entry of large insects, though extremely small pests may still pass through.
Can I paint this vent to match my bricks?
While the beige color is standard, if painting is necessary, ensure you use a masonry-compatible exterior paint that does not clog the 4mm drainage opening.
How many vents do I need for a standard wall?
Vent spacing should follow local building regulations and the specific drainage plan for your wall, typically every 450mm to 900mm.
Is this product suitable for retrofitting?
This product is designed for installation during the bricklaying process. Retrofitting into existing solid walls is not recommended.
Troubleshooting
Vent face is not flush with the brickwork
Adjust the seating of the vent within the mortar joint before the mortar sets, ensuring the ribs are fully engaged.
Water appears to be pooling behind the vent
Ensure that the internal cavity tray or flashing is properly sloped toward the weep vent and that no mortar bridging is blocking the internal opening.
Pros and Cons
Pros
- Discreet, aesthetic finish that blends with brickwork
- Self-cleaning design reduces maintenance requirements
- Easy installation with standard mortar keys
- Effective barrier against large insects
- Durable construction for long-term wall health
Cons
- Requires precise alignment during bricklaying
- Limited to specific perp joint sizing

Setup, Compatibility & Care
Installation
- Ensure the perp joint is prepared according to your building design and drainage schedule.
- Insert the G953-BU vent into the perp joint as the brickwork is laid.
- Ensure the upper and lower ribs are fully bedded into the mortar to create a strong, permanent bond.
- Check that the front face is flush with the outer brick surface to maintain a clean finish.
Compatibility
This vent is compatible with standard metric brick sizes and is primarily intended for use in masonry cavity wall construction. The beige finish is designed to complement light-to-mid tone brickwork.
Care
Minimal maintenance is required. Periodically inspect the vents for external debris or spider webs. If blockage is suspected, the tapering outlet allows for easy flushing with a light stream of water or compressed air.
