Materials and Connections

Of course, in our goal of carrying water to and from a building, we need to choose the proper pipe material to use. Every type of pipe has it's own style of fittings and method of connecting those fittings.

There are many styles we can choose from, and the popularity of each has changed throughout the years. Most fittings, however, have many similarities regardless of the material that they are made from. We are going to use copper for our example(which is still popular for potable water distribution, but was once also used for drainage too.)


Names for Basic Fittings

  • 1. Elbows(90's,ells). these range from 1/2" to 1 1/4"
  • 2. 45's
  • 3. male adapters(one side is male pipe thread)
  • 4. female adapters(one side is female pipe thread)
  • 5. street 90's(the word street is used to designate that one side of the fitting is the size of the pipe, which means it will go into a fitting.)
  • 6. street 45's
  • 7. Tee's(T)

More Fittings

  • 1. cap
  • 2. couplings
  • 3. 1/2"x 3/4" coupling
  • 4. ball valves
  • 5. stop and waste valve
  • 6. baseboard tee's(1/8" thread)
  • 7. union
  • 8. 3/4 x 3/4 x 1/2 tee
  • 9. 3/4 x 1/2 x 1/2 tee
  • 10. 3/4 x 1/2 x 3/4 tee
  • 11. 1/2 x 1/2 x 3/4 tee
  • 12. 1/2 x 3/4-copper x male adapter

The fittings in the basic list are the building blocks of all the different pipes, with a few exceptions. There are countless other variations to many of the other types of pipe, too. PVC for example has many odd fittings that are not normally used, a few of which, some plumbers don't even know exist! Here is where your large home supply stores do come in handy. There is a large selection of fittings and material readily visible so that all of the possibilities are right out in the open.

As for the actual methods of connecting each type of pipe, we will deal with that in each specific location in this site.
