solvent weld waste fittings/overflow fittings turned yellow

[stratplus]

Thought these only turned a yellow tint when uv hit them?
Had some kept in a dark shed for a while in a plastic tub and they have started to turn yellow, especially the overflow fittings.

The white rainwater used to go pink in UV.

But don't worry, there is no additional charge for the colour-morphing fittings.

Its the amount of fire retardant in the plastic that turns it yellow after a few years.
