Do you know the difference between a "street ell" and a "dielectric union"? A thorough understanding of plumbing systems is not possible
without knowledge of the importance of fittings. While fittings are small and seldom seen,
their importance cannot be overstated. Fittings
provide the accessories to complete a plumbing system. Couplings allow multiple pipe sections to be
connected. Elbows provide the mechanism
for pipes to change direction. Unions
are essential for easily disassembling plumbing systems for maintenance and
repair.
Plastic, steel and copper water piping systems will be covered,
for waste systems plastic and cast-iron piping will be discussed. The unique connection methods for each piping
material will be reviewed. While there
are dozens of fittings available to the plumber only the most common ones will be
presented including, couplings, elbows, unions, nipples and reducers. The cause of galvanic corrosion will be examined
along with the fitting that prevents this type of corrosion.
At the conclusion of this training you will be able to describe
the connection method of various pipe materials and the tools and techniques
required. You will be able to identify
and describe a “street ell” and a “dielectric union”. You will become aware of troubling procedures
for leaking unions. Finally, information
on drain piping and the connection methods using “no-hub fittings will be
presented.
