I think if MR Plumber/Spreader turned up yesterday I would have punched him.
Doing my testing, and had no ring continuity, so clearly there was another socket somewhere.
Being that it was last year that i 1st fitted, I couldn't remember where else there was any sockets, neither could the customer.
So had to crawl through the very tight loft to follow my cables, found another drop, then smashed his ****ing plaster off.
I had to repeat this twice more, and I finally had continuity...
(each time I found one, the customer would go, "ohh thats for the....)
To say I was royally ****ed off was an understatement.......
