My son had a new boiler fitted into the house he rents a couple of years ago. Landlord arranged it and didn’t use her regular plumber/heating engineer as he was 'too expensive'. She had it done on a fixed price by BOXT who I’ve heard nothing good about. Don’t know what make but it’s a conventional vented system. My son reckons a 17 year old came and fitted it. All been fine and her regular engineer has been servicing it. It was supposed to be serviced in December but the regular guy 'forgot'. Anyway, my son phoned him yesterday to remind him, he said he had a cancellation and came round yesterday and serviced it. This morning at 5.00 my son was woken by hot water ****ing out of the landing ceiling, the ceiling has come down, carpet and wallpaper ruined, even the downstairs is flooded. Called the 'forgetful' engineer out and he was straight round on an emergency call out. Basically switched the water off and is coming back later and says the installation is at fault and he's got to cut some pipes out and replumb it. Sounds like bullshît to me but could he have done anything during the ‘service' yesterday to cause this? It’s not going to cost my son anything as the landlady is insured up to the hilt on that house but just curious. Any ideas or just bad luck/co-incidence?
