Its horrible, I mean I trust my work but you are at the mercy of fittings and pipe further along the floor that may have a dry joint or a pushfit to nearly pop out.I know exactly that end of the world feeling. Am sure big relief for you Phil, but I bet you didn’t get over the initial shock and worry for a day?
Worst false alarm I had was after I worked in a multi story apartment on a top floor flat and next day reports were the flat below was getting flooded.
I imagined I had somehow destroyed all the flats below and rushed to find no sign of water in flat I worked in. Got a phone call the next day to say it was a mistake and flooding was on another apartment block. Genuinely made me feel ill.
If that call had have come in on holiday it would have ruined it.
