first i wouuld be cautious with any person who called themselves a surveyor,, many years a go i did a long course at collage,,,, on that course were mostly trades men,, and a few surveyors,, one day one of the surveyors was asked me if i could fix a burst at is home for him,,he knew the theory behind the problem,, but was unable to but it in practice,, that same person got his qualifications and is now advising people with heating or plumbing problems etc,, ,,,,, still do work for him but its only as hes to busy to do it himself always makes me smile],,, a sump is a small hole in the ground usually built in brick and around 2 feet deep inside will be an electric pump when the sump fills with water the pump starts up to pump it away,,, have you been under the floor to check,,,,,, if theres no pump it could be a drain vent unlikely
