(1.) That all new drains be constructed according to deposited plans to
be approved previously by the Medical Officer of Health and by the Engineer
to the Vestry.
(2.) All drains shall be made of glazed stoneware or cast-iron pipes. When
stoneware pipes are used they shall be socket-pipes of the best quality, and
shall be jointed with cement made of two parts of clean, sharp sand and one
part of best Portland cement by measure, and so as to be watertight, and,
where fixed inside the house, shall be embedded in concrete at least six inches
in thickness all round, made with one part of clean, sharp sand, five parts of
clean ballast, and one part of the best Portland cement ; main drains shall be
at least six inches in internal diameter, and branch drains at least four inches
in internal diameter. When cast-iron pipes are used they shall be socket-pipes
of best quality and heavy metal, and coated internally with Dr. Angus Smith's,
or some other approved, anti-corrosive composition ; the joints shall be caulked
with lead and the pipes not less than four inches in internal diameter.
(3.) The interior of such pipes, after being laid, shall be cleared from any
projecting portions of cement or other material.
(4.) The drain is not to be tilled or covered in until it has been inspected
and tested by an Officer authorised by the Vestry.
(5.) No drain shall be laid on the premises unless the drain from the sewer
to the premises is in good condition, and allows a sufficient fall to the house
drain or the greatest fall permitted by the depth of the sewer.
