Lead pipes and drinking water
A lead pipe rises to the kitchen tap. Has the survey tested the drinking water?
The drinking water has not been tested. A lead pipe rises to the kitchen tap, and that was recorded as pipework the survey could see. A home survey does not sample the water from that tap and does not send it to a laboratory. Seeing a lead supply is not a result for the water you would drink. The report names the pipe. It has not decided that the water is acceptable or unacceptable. Do not sand, scrape or cut the lead to try to confirm the metal.

What is the fuller explanation?
Lead pipework can be recognised by its look, its softness and the way old supplies were run to a kitchen. Recognition is still only identification of a material. Lead in drinking water is a sampling question, taken in a set way and read by a laboratory, and none of that happened on this visit. Other pipes in the house were not proved lead or proved otherwise. The kitchen riser is the run that was seen. The glass of water was not analysed.
Ask the solicitor for any water-quality sample, pipe-replacement note or water-company letter the seller holds. If you need to know about the water itself, a proper sample is a separate instruction, not a rewrite of this survey. Tell a lender the survey found a lead pipe to the kitchen tap and did not test the water. Leave the pipe undisturbed. Scraping it would not create the laboratory result you still do not have.
What should you ask your surveyor?
- Was a sample taken from the kitchen tap on this visit?
- Does seeing the lead riser amount to a laboratory result?
- Were other supply pipes in the house proved to be lead as well?
What are the typical next steps?
- Treat the lead riser as seen pipework, not as a water test.
- Ask the seller for any sample or pipe-replacement paper they hold.
- Arrange a proper water sample if you need a result for the tap.
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
Does the kitchen riser mean every tap was traced?
No. The pipe that was seen rises to the kitchen tap. Other taps, tanks and hidden runs were not followed and were not sampled. One visible riser does not map the whole plumbing. The survey has not called the rest of the installation lead-free. Only that kitchen run is the finding.
Should you scrape the pipe so a lender can see the metal?
No. Do not scrape, sand, drill or cut the lead. Marking the pipe does not test the water and can damage the supply. The survey already records a lead pipe to the kitchen tap. A lender needs that sentence, not a fresh scar on the metal. Any water test is a sample, not a scrape.
