Drain camera for a blocked drain
Updated: 23 October 2026
The kitchen gully has filled again, the chemical cleaner did nothing, and you want to see whether the cause is roots, wipes, or a broken pipe before anyone starts rodding. A drain camera for a blocked drain can show the face of that mass and the distance along the rod. It cannot clear the pipe, and it cannot see the wall hiding behind the blockage. This page uses drainage firms' own descriptions of what a survey can see, Scanprobe's warning not to ram a camera, and the twelve listings in the [sewer camera comparison](/hub/measuring-equipment/sewer-camera). We did not jet a drain. No survey fee is stated here. A qualifying purchase through our links can earn a commission at no extra cost to you.

A blockage you can see is not a pipe you have cleared
The head is a camera, not a rod. Pushing it into the mass to break through is how lenses crack and cables kink. Scanprobe tells users to pause, note the distance, and clear the blockage with the proper tool, then look again. A trade camera manual, for a different brand, says not to use the head as a cleaner. Those limits apply to a home reel as well. If the rod stops and the picture is a brown wall, you have found the face of the blockage. You have not restored the drain.
United Kingdom texts on the shared Sanyipace S8417 file include a buyer who got the camera because the drains kept blocking, and who praised the length. That is a reason people buy these reels. It is not a cure rate, and the same file describes units that failed after little use. The sequence for getting the head in without climbing down is on the how to use a drain camera page. This page is only about what the frame means once you are there.
What the picture can separate
At the face of a blockage you can often separate a few coarse cases, and you should say when you cannot. Roots usually look like pale strands or a mat coming through a joint, with pipe wall still visible at the edges if the lens is clean. A solid mass of wipes or grease fills the bore and has no strands. Standing water with a soft, even colour, and no joint in frame, means you have not reached a solid stop yet. A sharp edge of broken pipe, or a flat wall that is not the usual round bore, is a reason to stop and get a firm, not a reason to keep pushing.
You will not see every defect on one pass. Silt, grease, and a dirty lens hide the crown of the pipe. Drain CCTV, writing about root ingress, says a survey shows the surfaces the camera can see, and that a blocked line often needs cleaning before the wall is visible. If your frame is only the face of the mass, write that down. Do not upgrade it into a claim that the rest of the drain is sound. A 17 mm head may reach a tight bend that a 23 mm head never enters. Who that head is for sits on the best drain inspection camera page.
Film first or clear first
Film first when the access is yours, the flow has only just failed, and you can still see a shape. A soft mass a metre from a rodding eye is worth one careful look, because the distance and the appearance tell the drainer what to bring. Note the metre mark, or how much rod left the reel, before you pull out. Then rod or otherwise clear with a tool made for that, not with the camera.
Clear first, or ask a firm to jet, when the line is too dirty to see. Firms say they jet grease and silt before the lens can read the wall, and that silt can abort a survey. Do not invent a jetting pressure for a garden hose.
After the flow comes back
A drain that runs again is not a repaired drain. Cutting or rodding roots restores a hole through the mass. Drain CCTV's note on surveying after root cutting says the cutting does not close the joint the roots used. The opening is still there. A second look, after the flow is back and the lens can see the wall, is a different question from the first look at the mat. If you only filmed the face, you still do not know whether the joint is open.
Repeating blockages every few months are the pattern that outgrows a home clip. You can show a firm the access, the distance, and the earlier frame. You cannot hand them a grade. Grades from 1 to 5 belong to a coded survey, not to a camera menu. No failure rate for these cameras is claimed here, and no price for that survey either.
What to hand a drainer
Give them four things: which cover you opened, which way you pushed, the distance on the metre mark or the rod, and what you could see before the view stopped. A sentence such as "from the front chamber, about 8 m toward the boundary, a root mat, could not see past it" is enough to brief a visit.
Stop before you film if the only access is a public sewer. In England and Wales the 2011 transfer moved many shared sewers and laterals outside the boundary to the undertaker. It did not do that in Scotland or Northern Ireland, and it did not make every garden drain public. If you are unsure, ask the water company before you lift a cover in the road. A home camera does not become a permitted survey because the blockage is on your side of the smell.
Common questions
Can the camera push the blockage through?
It should not be asked to. The head is there to show the face of the mass and the distance, not to punch a hole. Forcing it cracks lenses and kinks rods, which is the failure drainage-camera workshops see when a camera was used as a rod. Clear the blockage with a tool meant for clearing, then look again if you still need the wall. A camera that breaks through has not repaired the joint.
Should I rod or jet before I film?
Film first if you can already see a shape near an access you own, and write down the distance before you disturb it. Clear first if the bore is full of grease or silt and the frame has no edges. Specialist firms jet in that second case so the lens can see. Do not invent a jetting pressure for a garden hose. If you cannot get a view after one wipe of the lens, hand the job on.
What do roots look like compared with wipes or a broken pipe?
Roots tend to show as strands or a mat at a joint, sometimes with wall still visible beside them. Wipes and grease tend to fill the pipe as a solid mass without strands. A broken pipe can show as a sharp lip or a shape that is no longer a round bore. If the lens is dirty, all three look brown. Wipe it before you decide. If you still cannot tell, say so. A wrong label is worse than a note that the view stopped.
Will one clip show every defect?
No. You see the surfaces in front of a clean lens, up to the point the rod stops. A blockage hides everything beyond it. Grease on the crown can hide a crack even after water is moving. One pass from one access is not a survey of the whole run. A second look after the line has been cleared is how the joint, rather than the mass, gets into the picture.
When is this a public sewer problem?
When the pipe is a shared sewer or a lateral that the 2011 transfer in England and Wales moved to the undertaker, or when the only way in is their chamber in the road. That transfer did not apply in Scotland or Northern Ireland. Do not lift a public cover to film it yourself. Ask the water company. A camera on your own private run, inside your boundary, is a different job from working on their sewer.
