Lead pipes and drinking water
The report mentions a lead main next to the front path. Has drinking water the survey did not sample been tested, or only named?
Only the pipe was named, not a water test. A lead main beside the front path was recorded as a supply pipe the survey could see or reasonably identify at that point. Drinking water was not sampled. A lead pipe in the ground does not measure what reaches the tap and does not show whether the lead continues under the house. The report notes the main. It has not tested the water and it has not decided the supply is affected or clear.

What is the fuller explanation?
Service pipes in lead were laid to many older houses, often rising near the front path or the stop tap at the boundary. Seeing a dull grey pipe at that point can justify calling it a lead main, but the buried length, the water-company side and the internal plumbing may differ. None of that is a sample of what you drink. The survey did not run a laboratory test and did not open the pipe. Identification of a visible length is the whole of the finding.
Ask the solicitor to enquire with the water company and the seller about lead replacement and any previous sample. A proper water test is a separate instruction and is not produced by looking at the path. Tell a lender the lead main was named and the drinking water was not sampled. Do not disturb the pipe to prove the metal. The survey's limit is already clear: seen at the path, untested at the tap.
What should you ask your surveyor?
- Was the lead main only identified beside the front path?
- Was drinking water left unsampled?
- Has the buried continuation of the pipe been left unmapped?
What are the typical next steps?
- Treat the lead main as named and the water as untested.
- Ask the solicitor to enquire about replacement and any earlier sample.
- Do not tell a lender the drinking water was tested.

Also asked about this
Does a replaced kitchen tap clear the main in the path?
No. Internal taps can be new while the buried supply remains lead. The survey named a lead main next to the front path and did not sample the water. Ask the solicitor where any replacement stopped. A new tap is not a new communication pipe and is not a water test.
Is the stop tap in the pavement the same pipe as the one by the path?
Not necessarily. The water company's pipe and the owner's supply pipe meet near the boundary, and responsibility is a question for the company and the solicitor. The survey saw a lead main by the front path. It did not trace ownership and did not sample the water. Do not assume the whole run is yours, or that none of it is.
