When does the option to reject for a defect expire?
The option to reject for a defect expires by non-exercise or by acceptance of the defect after knowledge thereof, by dealing in the thing contracted for even prior to such knowledge, by its being destroyed or damaged after receipt, or by its being increased prior to receipt by way of direct connection with the thing, not arising from the thing itself, by the act of the purchaser, or after receipt by way of a single increase arising out of the thing itself.
