Second Level Support
Over the Australia Day weekend I put some effort into a few home maintenance tasks. I cleaned my air-conditioner filter, patched and painted some wall-holes, and re-sealed a leaky shower screen.
Finally, already picturing the beer I'd drink, I went through the motions of replacing the washer and valves in my shower taps. It had been dripping for a while, and the easy fix would be the pineapple on top of my handyman shenanigans. But, when I put the water back on, it still dripped. I tightened, rechecked, went up and down the stairs a bunch of times. No difference. I couldn't solve it.
So I did the mature thing and closed the door and walked away.
After a week of showering in the spare bathroom, I decided to tackle the problem again. I bought new valves and washers, essentially I would repeat the whole change process. A reboot. The first step in IT troubleshooting, turn it off an on again! And it worked! Finally, with the taps turned, the water stopped. At last, I could beer.
The next day, with water flowing, a high pitch whine started in the walls. I Googled it, saw the list of possible root causes... Plumbing is not like IT.
