A drain survey before buying a house can help you check the condition of underground pipes while you still have time to ask the seller questions. It can be particularly useful if your home survey flags a drainage concern, the seller reports recurring blockages or you want to understand the condition of an older drain.
Does a home survey check the drains?
It depends on the level of survey and what the surveyor can safely reach. For example, the RICS Level 2 scope includes a visual check of accessible inspection chambers where covers can be lifted safely and without damage. A view into a chamber tells you about what the surveyor can see from that point. A camera inspection lets an engineer look along the pipe itself.
First, read the drainage section of your home survey. If it mentions limited access, ask which sections the surveyor could see and whether they recommend a closer look.
What can a drain survey before buying a house show?
An engineer feeds a camera into accessible pipework. The footage can show issues such as cracks, displaced joints, tree roots or debris. It can also help pinpoint where a visible problem sits, which is useful when you ask about repairs. See what a CCTV drain inspection involves.
However, the inspection depends on access and visibility. A stuck cover, standing water or a blockage may prevent the camera from reaching part of the drain. Ask the engineer to record which sections they could inspect and which they could not. If a section needs clearing or another visit, ask what the follow-up would involve.
How to arrange a drain survey before buying a house
Ask the seller or estate agent to agree a time and confirm who will let the engineer in. If you know where the drain covers are, share that information in advance. Also mention any recent drain work, repeat blockages or past flooding. Even a short note about where an issue appeared can help the engineer decide which pipe run to check first.
If you want the results before exchange, tell the engineer your deadline when you enquire. Allow time to read the report and ask questions, especially if an inaccessible section needs another visit.
What to ask for in the report
- Which pipe runs did the engineer inspect, and where did the camera stop?
- Can you match each finding to its location and an image or a point in the video?
- Which findings need prompt attention, and which can be monitored?
- Does the report recommend a further check, and what would that resolve?
Finally, if a defect appears near a boundary or on a pipe that may serve other homes, ask your conveyancer or wastewater company to check who is responsible. Share the relevant part of the report so they can see where the issue was found.
