Description
BWT Aquareva skimmer weirs light blue (set of 2)
The BWT Aquareva skimmer weirs light blue 40031143 are original replacement flaps for Ady, Aquareva and Série France skimmers.
Supplied as a set of two light blue weirs, they restore proper surface skimming and give a clean, uniform look to the skimmer mouth when the
original flaps are worn, broken or discoloured.
Key features of the BWT Aquareva skimmer weirs
- Original BWT Aquareva skimmer weirs supplied as a set of two pieces.
- Light blue colour that matches Ady, Aquareva and Série France skimmer fronts and accessories.
- Floating flap design that follows the water level for effective surface skimming.
- Helps guide floating debris into the skimmer basket and reduce its return to the pool.
- Designed as a direct replacement for skimmer weirs referenced 40031143.

Compatibility and typical applications
These light blue weirs are used on several BWT Aquareva, Ady and Série France skimmers and are also listed for mirror skimmer systems
using the Badu EasyFit option 4 configuration. They sit in the front opening of the skimmer body and pivot with the water level to create
a thin surface flow that carries floating debris towards the basket.
Always verify that the spare parts list or exploded view for your skimmer specifies reference 40031143 and compare the shape of your existing
weir with the new part. If the reference and geometry match, this weir set is the correct replacement for your installation.
Function of the skimmer weir
The skimmer weir acts as a floating flap that partially restricts the opening of the skimmer.
When the filtration pump is running, water is drawn over the upper edge of the flap, creating a concentrated surface current that captures
leaves, insects and other floating particles. When the pump stops, the flap rises and limits the return of debris from the basket to the pool.
- Improves the efficiency of surface skimming by concentrating the flow at the waterline.
- Reduces the risk of collected debris flowing back into the pool when the pump stops.
- Helps to stabilise the water level in the skimmer throat under normal operating conditions.
When to replace the skimmer weirs
Weirs are continuously exposed to sun, chemicals and mechanical movement.
Over time the hinges or clips can weaken, the flap can warp, or the surface can become heavily discoloured, which reduces both function and appearance.
- Replace the weirs if the flap no longer floats correctly or does not follow the water level smoothly.
- Replace the weirs if the hinge pins, side clips or locking tabs are cracked or broken.
- Replace the weirs if the plastic is badly warped or interferes with the movement of the basket.
- Consider replacement if the colour has severely faded and no longer matches the skimmer front.
Installation and adjustment guidelines
- Stop the filtration pump and remove the skimmer basket to gain clear access to the weir.
- Release the old flap by unclipping the hinge or side pins as indicated in the skimmer manual.
- Clean the hinge supports and surrounding area to remove scale and debris.
- Position the new BWT Aquareva skimmer weir and clip the hinge pins or side tabs into the supports.
- Check that the flap can move freely and returns naturally to a slightly tilted position towards the pool.
- Reinstall the basket and restart the filtration system, then observe the weir in operation to confirm smooth movement.
Correctly installed skimmer weirs help maintain efficient surface cleaning, limit visible dirt on the waterline and support the overall
performance of the pool filtration system.
