Fixing inspection chamber (and/or rodding point)

[ringi]

I have a 1930’s clay pipe damage system with no inspection chambers or rodding points! The gullies are not rodable, I think they have Q bands from what I can feel.

I don’t like not being able to clean the drains…. I can’t get a drain cleaning jet hose far past the Q bands – but have only tried a “DIY� spec hose on my domestic power water.

One of the gullies can be replaced as part of doing other work; however the other gullies are in paving I do not wish to disturb. So I am thinking of an inspection chamber at the point(s) the pipes join to allow rodding back to the gullies.

I assume that the pipes are all at the same level when they join, however when I look at pre-made inspection chambers on the web, the images see to show the pipes from the side at a higher level, so not making them an easy replacement for a “T� joint.

I have not yet uncovered any pipes, so don’t know what I am dealing with in detail.

Comment s please on what my options are…

What sort of costs am I likely to be looking at? (Maybe I just do nothing and pay £200 every time I get a block – assuming a professional jet hose will bit past the Q bands)

I know you dont want to play with other paving and i dont know how many gullies there are but maybe changing them for bottle traps would be a simple route.

its very unlikely you have no inspection chambers
probably one covered up someplace
