pipe and heavy malleable iron fittings. Ream the
ends of iron pipe and use thread sealant for an
airtight system.
D Use long sweeping bends for turns in piping; avoid
unnecessary turns.

Ream the ends of iron pipe.

D Avoid using unions and other connections
underground and in hard to reach places.

before installing them. Start the connections at the
storage tank end.
D Flush and test the lines under pressure before
covering or cementing in place.
