You gotta turn it off near the floor.

The shower continues to sabotage our domestic existence. The warm tap—or just the handle?—has gone mental. We tried taking it apart, installing new pieces, etc. And for a little while (a day?) it seemed to work okay. Now, you can sometimes spin the warm tap around and around and it makes no purchase. Once hot water comes out, it comes out strong and very hot. To turn it off, you need to turn it off at the little pipe by the floor. I don't know the technical terms, and I don't want to know! I will not stain my patriotic mind with such words. It smacks of collusion! Some say we must know our enemy. Yeah, nice try.
