Cleaning cloth should be outside the end of the pipe and accessories Internal, if necessary, increase the amount of coating to ensure that the surface adhesion;

(5) the pipe into the socket to insert into the plug so far, marked on the pipe into the depth of the marking, the depth of the socket should be the depth of 1/3 to 3/4, and marked on the pipe socket Depth marking

(6) CPVC glue must be applied on the surface of the pipe after the cleaning agent, rather than wet when coated. Brush should be used to brush CPVC glue, brush width should be 1/3 to 1/2 of the diameter. First coated mouth, after the coating socket, should be axial brushing, repeat 2 to 3 times.
