The hot water heater has a beautiful, new regulator valve, with a PVC pipe run, which empties itself (when it chooses to do so) outside.
Hopefully it will not be doing that in the near future. But whenever it does, the water will be useful in the environment, not collected and poured down a drain. Recycled, no? Very correct.
The plumber recommended not storing the oddments back in the room with the water heater, for about a week, juuust in case the regulator was not the complete answer to our problems. He knew how much work it took to shift all those necessary oddments. It would be awful to have to do it twice in a week, he opined.
We opine, too.
