Fitted a lower complete immersion the end of last month for a tenant.....all good. Tenant rang me last week saying it wasn't working, so I went around and on closer inspection there is very slight weeps from the live/neutral connections of the element. Told the tenant I will sort it. Went to merchant and he said he would replace the element.....but what about my time for re doing the job? No answer on that! Where do I stand?
