Replacement of lead pipes30
1
The relevant supplier must modify or replace its part of a pipe where a relevant supplier—
a
has received from the owner of premises to which water is so supplied notice in writing—
i
of the owner's intention to replace so much of the pipe as belongs to him; and
ii
of his desire that the relevant supplier replaces the remainder of the pipe; and
b
has reason to believe that water supplied by it for regulation 4(1) purposes from a pipe to which paragraph (2) applies contains, at the consumer's tap, a concentration of lead which exceeds 10 μg/1.
2
This paragraph applies to a pipe—
a
of which the major component is lead;
b
which is subject to water pressure from a water main or would be so subject but for the closing of some valve; and
c
of which part belongs to a relevant supplier and of which the remainder belongs to the owner of any premises to which the relevant supplier supplies water for regulation 4(1) purposes.
