Retrieved from the bin

The Airbnb we were staying at had a weird plumbing system, the only hot water was from a Quooker tap in the kitchen. (The shower was a separate electric type).
The kitchen heater had a fault and would only provide cold water so the owner got a repairman organised who came yesterday while we were out and fixed it. When we got back and were tidying up after dinner I noticed something shiny in the waste bin.
I was pleased to find two brass nuts and a 10mm box spanner. The brass fitting was choked with scale when I found it but flushed out under the tap and clearly didn’t need replacing.
Anyway all these goodies will find a home in my workshop.
