Just the boiler. Everything else worked fine.
The story....
First fixed and second fixed a house.
Cent heat wired to the CU via an FCU.
Plumber wanted to commision, and without asking, disconnected the FCU and wired it directly to a plug top to power the whole cent heat circuit.
I didn't get along with the plumber to begin with, as we had 'stolen' his sons job (quote was cheaper
).
The system didn't fire up. The valves worked, the pump fired etc etc, but the boiler didn't fire, and showed an error.
The plumber got his son to have a look with out ringing us. His son found the live and neutral reversed at the boiler(as in the flex brown was neutral, and the flex blue was live
). Without removing any other covers, he put the blue into the live terminal of the boiler and the brown to the neutral. (dick head).
The plumber couldn't wait to throw abuse. I new I had done it properly. Can't get a lot wrong with colours!!!!
The first thing I tried was the extension lead he had plugged the whole system into - It was reverse polarity (good old plug-in martindale socket tester
). Checked the site temp supply socket that the extension was plugged into - all ok.
The extension was wired with reverse polarity in the trailing end.........The plumbers son had made it up from some old flex and a plug and trailing socket
That was a great day, I made sure I kept abusing the plumber all day - As he had to me when I first arrived of site
