Special reminder: The issues that need special attention in waterway reconstruction are as follows:
(1) The selected water pipes and related fittings must be products of the same brand and the same material;（IFAN pipe and fittings are good choice.）
(2) Useless joints should be minimized as far as possible when laying waterways and pipelines;
(3) Do not lay the pipelines with long-distance horizontal grooves for buried water pipelines on the wall;
(4) The buried pipeline on the wall cannot be slotted diagonally to lay the pipeline;
(5) The pressure test shall be carried out after the renovation of the plumbing line;
(6) Suppressing plumbing pipelines is not the higher the pressure, the better;
(7) The plumbing pipeline is not suppressed as long as possible!
