Description
BWT Aquareva Skimmer Weirs Anthracite Grey – 40031743
The BWT Aquareva skimmer weirs anthracite grey 40031743 are original floating flaps for in-ground skimmers.
Supplied as a set of two in a dark anthracite grey colour, they restore correct surface skimming and give a modern, discreet look to the skimmer opening
when the original flaps are worn, broken or discoloured.
Key Features Of The BWT Aquareva Skimmer Weirs

- Floating flap design that follows the water level for efficient surface skimming.

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 particles. When the pump stops, the flap rises to reduce backflow and helps keep collected debris inside 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 return to the pool when filtration stops.
- Contributes to stable water behaviour in the skimmer throat during operation.
Compatibility And Identification
These anthracite grey weirs are intended for skimmers that use the reference 40031743 in their spare parts list.
They are mounted at the front of the skimmer throat and pivot freely with the water level.
Before ordering, always compare the part number and the shape of your existing flap with the new weir set to ensure a correct match.
If your current skimmer weirs carry the same reference or your technical documentation specifies code 40031743, this set is suitable as a direct replacement.
When To Replace The Skimmer Weirs
Skimmer weirs are exposed to UV light, pool chemicals and constant movement.
With time the hinge area or side clips can weaken, the flap can warp, or the surface can become heavily discoloured, which reduces 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 on the skimmer body or interfere with removal of the basket.
- Replace the weirs if the anthracite colour has become strongly faded, chalky or patchy.
Installation And Adjustment Guidelines
- Stop the filtration pump and remove the skimmer basket to obtain clear access to the flap.
- Unclip the old weir from its hinge supports, following the procedure given in the skimmer documentation.
- Clean the hinge area and surrounding surfaces to remove scale, dirt and any 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 anthracite grey weirs, the skimmer regains efficient surface cleaning and a modern, neutral appearance that coordinates with dark grey coping
and terrace finishes around the pool.
