my letting agency got the hump with me this week.......
they asked me to pat test a property and carry out my basic basic safety check
lights kept blowing fuses,,,,,,malicious change of wiring in a pull switch in the bathroom
a few other bits and bobs and then got a call saying the immersion time switch had burnt out and that they new i hadnt tested it as there wasnt a sticker on it!!!!!!!!
and i said you didnt tell me the property was a canabis factory previously otherwise i would have recommended a PIR !!!!!!
Change the time switch programmer and now waiting for the plumber to change the immersion element
