The household comprises two adults and a dog. The dog is calm. The tenants have asked whether the Bureau can help, and, if not, whether it can recommend a plumber.
Boiler cycling down. Water hammer in the wall. Cupboard catch worn. A plumber has been recommended, as requested.

Rhythmic knocking in the wall, three or four knocks at a time.
Knocking at 02:00 to 03:30 in cold weather, in an older house, matches the timing of a boiler cycling down. The cupboard door has a worn catch. The dog’s lack of concern is, in the Bureau’s experience, the most reliable indicator on file. Recommended: Director’s review.
