Just had a blockage in my main drain, just about on the hedge line. I poked a hose down but didn't have any rods so I called out a drains firm, They cleared it quickly enough with high pressure water jetting and said there were two or three snag points, probably roots. (It's plastic so far, then clay). They reckoned I should get a TV survey and, it it is roots, that they can sometimes be cleared with some sort of flail followed by lining, and that this would be covered by insurance. Anyone got any experience of this method? I would have thought it might be safer to dig it up (fortunately not under concrete).
Secondary question, the water jetter was a reasonably meaty petrol powered job in the back of a van, but would a suitable nozzle on a good domestic pressure washer work, at least for modest blockages? Anyone know any suppliers?
The clearance cost £115 plus vat (fixed price) and they were there within the hour. Only a ten minute job, but I thought that wasn't bad for Easter Sunday, being 20-odd miles from their base (the most local drains plumber was away for the holiday).
