Quick Fix
I fixed the guest bathroom stool today.
It took all of three minutes to get it fixed.
The thing had gone to honking, chirping, and humming in a rather obscene way at the most inopportune times.
It almost always happened when someone shut a faucet off quickly somewhere else in the house.
Sometimes it happened when we had guests in the house.
Sometimes, it spited us and made the noise when one of our guests was in there using it.
For a while, all it took was getting up from the chair we were sitting on, and flushing it. (or embarrassedly telling our guest through the closed door how to stop it)
That worked, sometimes.
Sometimes, after I had flushed it, all would be quiet, until I had walked a few strides away; then it would chirp in the haughtiest way, stopping, once I had turned to flush it again.
Finally, it got bad enough that a trip downstairs, around the coffee bar, down the hallway to the storage room, (often, in the dark) through the storage room to the mechanical room, and a decent stretch across all the luggage that is stored under the manablock was required to shut the valve off to it entirely.
This worked. Until we forgot to turn it back on.
And one of the sweet daughters used that restroom.
We were quicker to turn it back on after that.
We’ve probably made those trips to flush it, or shut the valve off downstairs for a couple of months now.
