Buying an 80 yr old house. Had full survey done - some lead piping noted in downstairs loo and garage. Kitchen extension and bathroom all redone within last 30 years. It's going to take over 3 weeks to get water co to do a lead survey and give results. Current owners have been there 50years and don't seem to have died of lead poisoning. Should we worry? Help please? (We're in a north east town so not a hard water area).
