Drainage and septic tanks
One clay joint at the chamber is displaced, and the rest of the run is buried. What would a camera see that this visit could not?
The displaced clay joint at the chamber is the joint this visit could see, not a survey of the buried run. One joint out of line at the open chamber says nothing reliable about the next joint under the ground. A camera, if it is later instructed, could see the bore, the joints and any gap along that run. The camera is not included unless it was agreed. This visit stopped at the joint in view.

What is the fuller explanation?
Clay pipes fail, leak or stay serviceable joint by joint. A lip, a gap or a dropped invert at the chamber is a reason to investigate. It is not a map of the drain, and it is not proof of collapse further along. Roots, silt or a clear flush, if noted elsewhere, do not enlarge this finding into a whole-run verdict.
Write down which joint, in which chamber, and that the remainder is buried. Do not let a quote for a full relay attach itself to one visible joint without a look along the pipe. The survey does not grant a discharge consent and does not invent a length of defective pipe. The unseen run stays unseen until a further instruction covers it.
What should you ask your surveyor?
- Which joint was displaced, and was it only the one at the chamber?
- Could you see any further length of pipe, or was the rest buried?
- Are you leaving a camera out of this visit unless it was agreed?
What are the typical next steps?
- Record one displaced joint at the chamber, not a failed whole run.
- Do not invent a length of broken pipe beyond what was visible.
- Agree a camera separately if you need to see the buried joints.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
What would a camera add that this visit lacked?
A view along the buried bore: further joints, gaps and the pipe away from the chamber. That view was not part of this visit unless it was agreed.
Does one open joint mean the drain has collapsed?
No. It means only that the joint at the chamber is displaced. A collapse further along the pipe has not been shown from this visit.
