1.   PIPE MANUFACTURER

1.1  All pipe is to be made of a long hole surrounded by metal or plastic.

1.2  All pipe is to be hollow throughout the entire length - do not use holes
     of different length than the pipe.

1.3  The internal diameter of the pipe must not exceed the overall diameter
     otherwise the hole will be on the outside.

1.4  All pipe is to be supplied with nothing in the hole so that the water,
     steam or other stuff can be put inside at a later date

1.5  All pipe should be supplied without rust; this can be more readily
     applied at the job site.
     Note: Some suppliers are now able to supply pre-rusted pipe.  If
     available in your area, this product is recommended as it will save a
     great deal of time on the job.

1.6  All pipe over 500ft (153m) in length should have the words "long pipe"
     clearly marked on each end so people will know it is a long pipe.

1.7  Pipe over two miles (3.2km) must also have the words "long pipe" painted
     on the middle so people will not have to walk the entire length of the
     pipe to determine whether or not it is a long or short pipe.

1.8  All pipe over 6" (152mm) in diameter must have the words "large pipe"
     painted on it so that it cannot be mistaken for a small pipe.

1.9  Flanges must be used on all pipe.  Flanges must have holes for bolts
     quite separate from the big hole in the middle.

1.10 When ordering 90, 34 or 30 degree elbows, be sure to specify right or
     left hand, otherwise you will end up going the wrong way.

1.11 Be sure to specify to your supplier whether you want level, uphill, or
     downhill pipe.  If you use downhill pipe for going uphill the water will
     flow the wrong way.

1.12 All couplings should have either right hand or left hand threads, but do
     not mix the threads.  Otherwise, as the coupling is being screwed on one
     pipe it is being unscrewed from the other.

1.13 When pipe is being installed in a "non-pressure" situation (e.g. gravity
     return, overflow or drain) the word "top" must be painted in a prominent
     position so that the water runs only on the bottom of the pipe.

1.14 The word "end" showing where hollow pipe stops, and solid pipe begins
     shall be clearly marked on all such sections.  No length shall have an
     "end" more than halfway from the middle, nor more than one "end" per
     length.

1.15 Each pipe length must be clearly marked with an arrow denoting direction
     of flow on each end.

1.16 Pipe will be either "unidirectional" or "bi-directional" and in such
     cases will bear the arrow symbol with the arrow head pointing to where
     the conveyed material is supposed to go.
