Lead pipes and drinking water
Where a report pairs a lead pipe with the kitchen stop tap, what stays open about a water test the survey did not take?
Water quality stays open, and so does how much of the supply is still lead. The report pairs a lead pipe with the kitchen stop tap as something seen, not as a sample. The survey did not take a water test. A visible lead pipe at the tap does not measure what comes out of it and does not map the buried main. The inspection recorded the pipe it could see. It has not decided that the drinking water is affected or unaffected.

What is the fuller explanation?
Lead pipe was used for many service pipes and for some internal runs. At a kitchen stop tap it may be the rising main, a short stub, or a fitting that looks like lead and needs a plumber to confirm. Even a confirmed lead pipe does not, by itself, give a result for the water, because that needs a proper sample taken in the right way. This visit did not take one. The open point is the water, not the fact that a pipe was described.
Ask the solicitor what the water company or the seller already knows about lead replacement, and ask for any previous sample paperwork. A water test, if you want one, is a separate instruction and must not be improvised by disturbing the pipe. Tell a lender the survey saw a lead pipe at the kitchen stop tap and did not test the water. Do not describe the supply as cleared because the tap ran on the day of the visit.
What should you ask your surveyor?
- Was the lead pipe only seen at the kitchen stop tap?
- Was drinking water left untested?
- Has the rest of the supply pipe been left unmapped?
What are the typical next steps?
- Treat the lead pipe as seen and the water as untested.
- Ask the solicitor for any replacement or sample records.
- Arrange a proper water test separately if you need a result.
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 a new kitchen tap prove the lead pipe has gone?
No. Taps are changed without replacing the pipe behind them. The survey paired a lead pipe with the stop tap and did not test the water. A new tap on an old pipe is still an old pipe. Ask the solicitor for replacement papers if the seller says the lead was removed. The tap alone is not those papers.
Who replaces a lead supply if one is confirmed later?
A plumber and, for the buried communication pipe, often the water company, under their own rules. The home survey does not do that work and did not test the water. Ask the solicitor to make enquiries rather than agreeing a job at the stop tap on a viewing. Any replacement sits outside this report, which only recorded the pipe it could see.
