A piece of rubber clamped firmly over the hole will hold it until the sprinkler guys can get here with a scaffold tower and replace the pipe section. I drive a few miles to another site, load up a wet-vac and the numpty labourer, who, as usual, is griping about being expected to actually work. "Why should I have to do it?", he whines, like an eight year old.
I set the old misery-guts to work clearing up pools of water and picking rolls of furnishing fabric out of the pale, slightly rust-tinged flood.
He brightens up when i tell him I'm leaving him there all day. Sweep the roadway, empty the bins, clean around all the fire-doors... A default activity that to him means "find a quiet corner out of sight of the cctv cameras and light up a cig".
Me? back to our main site to investigate a long term leak. The roofers and the steeplejacks have messed around up there many a time, they were ordered to scrape off all the old repairs, get right to the root of the problem and fix it.
But it's not fixed, the tenant below has water seeping out of his wall. And the tenant below him had a window-ledge full of wet, too.
Time to get a ladder again. My verdict is that there's something I can't see going on behind the parapet wall, and the only way to find out is to dismantle a yard or so of parapet, which requires a lot of full-on hefty bashing with a big hammer, and quite frankly? I'm feeling a bit destructive.
