I know, how can you not see a man hole? I mean they are as big enough for a man to fit in. But some times, someone will decide to cover them up… Nothing wrong with that, just as long as you tell the people who have purchased your house what you have done. In the case where you have no idea where it can be, we can help. Bristol Drain and Plumbing have loads of different kit to find and trace any drain. We can use CCTV to find the drain, then use a sonde and cat4 to pin point exactly where it is. Any issue you have with your drains, we are happy to help.
