How to go from cast iron or copper pipe to plastic.

You are doing some renovations and have an old cast iron pipe or a galvanized pipe in your home. You would like to run plastic, but the job seams too big.  Well, they have come up with some simple solutions when it comes to your project.  Mind you, there is some work involved, but it is easy to figure out, especially with the fittings that will take you to plastic pipe.   Fernco couplings have been around for a number of year and are ideal for many different applications.

Castiron pipe is exceptionally hard.  When this pipe is new it cuts very well with a set of ridgid chain cutters.  As time goes along and many years pass, some castiron can lose their hardness.  So it is most important to know that if you are going to cut castiron pipe with a chain cutter it is possible to crush it instead of cutting it straight.  I personally use a reciprocating saw and Lennox blades with 30 teeth per inch and I try and get the Gold grade as well.  They have the longest balde life that I have found to date.You will more then likely go through 2 or 3 of them to cut a piece of 4 inch cast.

Once you have performed this task; it is just a matter of loosening off the clamps and sliding the coupling over the pipe and then tightening the stainless steel clamp.  Now you are ready to run your plastic pipe.

It is also possible to replace just a piece of castiron or galvanized pipe with plastic by cutting out the section that is bad and  use 2 couplings.
