Description
BWT Aquareva skimmer weirs black – 40031943
The BWT Aquareva skimmer weirs black 40031943 are original floating flaps for in-ground skimmers.
Supplied as a set of two in a deep black colour, they restore correct surface skimming and give a strong, modern contrast at 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.
- Black colour that creates a clean contrast with light liners, tiles or coping stones.
- Floating flap design that follows the water level for efficient surface skimming.
- Guides floating debris into the skimmer basket and limits the return of dirt to the pool.
- Designed as a direct replacement for skimmer weirs identified by reference 40031943.

Function and role in the skimming system
The skimmer weir acts as a floating gate at the entrance of the skimmer.
When the filtration pump is running, water flows over the upper edge of the flap and creates a thin surface current that captures leaves, insects and other floating debris.
When the pump stops, the flap rises and reduces backflow so that collected dirt remains in the basket instead of returning to the pool.
- Concentrates the flow at the waterline for better capture of floating debris.
- Reduces the amount of trapped dirt that can wash back into the pool when filtration stops.
- Contributes to stable water behaviour in the skimmer throat during normal operation.
Compatibility and identification
These black weirs are intended for skimmers that use reference 40031943 in their spare parts list.
They are installed at the front of the skimmer opening and must pivot freely with the water level.
Before ordering, always check the part number in the technical documentation and compare the shape of your existing flap with the new weir set.
If your current skimmer weirs carry the same reference or your installation guide specifies code 40031943, this set is suitable as a direct replacement.
When to replace the skimmer weirs
Skimmer weirs are exposed to UV light, pool chemicals and continuous movement.
Over time the hinge area or side clips can weaken, the flap can become warped or the surface can show heavy ageing, which affects both performance and appearance.
- Replace the weirs if they no longer float correctly or fail to follow the water level smoothly.
- Replace the weirs if hinge pins, side tabs or clip-on parts are cracked or broken.
- Replace the weirs if they rub against the skimmer body or block basket removal.
- Replace the weirs if the black surface has become heavily faded, chalky or damaged.
Installation and adjustment guidelines
- Stop the filtration pump and remove the skimmer basket to gain clear access to the flap.
- Unclip the old weir from its hinge supports according to the procedure in the skimmer documentation.
- Clean the hinge area and the surrounding plastic to remove scale, dirt and sharp residues.
- Position the new BWT Aquareva skimmer weir and clip the hinge pins or side tabs into the supports.
- Check that the flap moves freely and naturally tilts slightly towards the pool side at rest.
- Reinstall the basket, restart filtration and observe the weir during a test run to confirm smooth movement and correct floating level.
With correctly adjusted black weirs, the skimmer regains efficient surface cleaning and a distinct, contemporary appearance that works well with light or dark pool finishes.
