Where to install
ASME A13.1 calls for a marker next to every valve and flange, at every change of direction and branch, on both sides of wall, floor and ceiling penetrations, and at regular intervals on straight runs — we recommend every 20 ft (6 m). Place markers where they are readable from the normal approach angle.
