Plumbing 101- Cutting Pipe and the Proper Plumbing Tools to Use

The proper measuring of plumbing pipe is probably one of the most important skills a plumbing professional can master and it?s also one of the things homeowners stumble on when trying to perform their own repairs. Believe us when we say there are plenty of plumbing professionals out there that we call ?try plumbers?, they put the pipe and fittings together loosely stick it up in the air to try it out, then take it down to cut it. It?s time consuming and ridiculous especially when you can follow a few simple steps to ensure a proper measurement.

The first thing you must know is the measurement you need from the center of one fitting ÿto the center of the other fitting. It makes no difference if the dimension is from the center of a 90 degree ell to a tee or the center from one 90 to another 90.

The next most important thing to find out is the fitting takeoff. The fitting takeoff is the dimension from the center of the fitting to the back of the cup, hub or threads depending on the material you are working with. Please see the diagrams below for examples of fitting takeoffs for various types of materials.
