Hayward Weir Flap
If the weir flap on your Hayward has cracked or crumbled, it's a part we can usually sort without chasing discontinued spares. With your sample on the bench this is a realistic reproduction job.

Why these break
Weir doors warp and jam the skimmer throat. Vibration fatigue does the damage: thousands of small flexes add up to a crack at the stress point, usually right where the part clips or pivots.
How we reproduce them
These take a proper modelling pass: we measure the mounting points and clip geometry from your part, reinforce the known failure point, and verify fit with a test print before the final run.
We print these in ASA. ASA is the UV-stable cousin of ABS — it holds its colour and strength through years of Australian sun where the original plastic went chalky and brittle.
As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
