Recently bought a house in Dublin. 1960's ex council property. My current neighbours who are Polish, one of whom is a plumber, have been doing work the house. They put in new oil boiler, now there seems to be endless problems which they need to fix. The first is that, from what I understand, there was water in the oil tank, and they had to drain off the water. They now suggest that the water is getting in through the vent, and the whole tank needs to be replaced as it is not possible to seal the vent. They say that although they have drained off the water from the tank, the oil in it would not be really good oil, and might damage the burner. I thought that if there was water in the oil, the boiler would not work at all, and it is working perfectly. The second thing is that they say that two of the radiators are not working, and they think there is a kink in the pipes in the ceiling or the floor. They said they will rod the pipes to see if they can find the kink, if not they will have to cut the floor and celinings open. I know they are very short of work at the moment, but I wondered if I was being conned? Any advice greatly appreciated.
