It is possible to buy waterproof endoscope cameras on ebay for less than £20.
Any one able to advise as to whether these are any good for inspecting drains and offer any advice as to which are the better ones.
For drains you need sufficient rigidity in the camera feed to push the came ra down the pipe, and sufficient length to get to any faults and identify t heir location.

I've done it (gutter drain, not sewer).
I taped mine to a drain clearing spiral wire.
The front tend to clag up, running a hose down with it seemed to help.
The picture is no where near as good as a proper CCTV survey, but it was useful and much can be seen.
A friend brought one and we brought a couple here, they are OK. Fist problem was finding something that could display the image. Seemed Skype was my best bet on the mac.
they are OK of course the qulity of teh image isn;lt great but then niether are the ones I see on TV being inserted into places I wouldn't want to loo k.
I have two sets of Wicks drain clearing rods. I was going to attach the camera to one end. One catch is that the rods have to be twisted clockwise to stop them coming undone. I think a 15m cable should be long enough.
I see no problem with that especially if you have a reasonably straight run. You might also use the thinner rods used for feeding wiring in wall cavities. I have several USB cameras, some on flexible stalks and others on "wire". In my experience their performance is broadly similar.

OP can twist the rods anticlockwise to wrap the wire round them before inse rtion, then use only the minimum possible rotation during insertion. The ri ght tool end shape really helps of course.

Plus you need some form of lighting. And very short focal length/wide angle.. ie inches.
