PPR Pipe Installation Method Statement: Clause Template

Blank PP-R installation method statement pages in a document sleeve on a site-office desk, beside an approval stamp, a vernier caliper and three green PP-R pipe offcuts

The package comes back with one line against it. “Method statement not specific to the proposed system.
