Example post: the stain under the sink
A new water stain under your sink is worth checking. It may help a plumber understand where moisture has appeared, but a photo alone cannot confirm the cause.
If it's safe to do so, take a wide photo of the cupboard and a close-up of the affected area. Avoid touching nearby electrical equipment.
