How to join cast iron pipe or copper pipe to plastic pipe using fernco couplings.

32 years of experience has taught me to use a few tricks when it comes to repairing plumbing problems. A reciprocating saw and a few metal cutting blades will cut your cast iron pipe and then you can attach your fernco coupling and you are all set to run your plastic pipe. When cutting cast-iron pipe it is best to buy blades that are better in quality as cast is very hard. I prefer Lennox blades with 18 teeth per inch and the gold brand if possible. You can try a set of cast iron cutters, but you are taking the chance of the cast cracking or crushing if it is old. Recipprocating saw works best for me. good luck...Please subscribe and have a great day.

I'm going to be replacing a shower that drains into cast iron piping. I want to use a PVC drain for the new shower and connect it to the existing cast iron system. Is this the type of product I would use? Thanks!

@brewcabbage Hello there;

A fernco coupling or an MJ coupling will work as well. I have used both although I prefer a fernco. This will do exactly what you are looking to do on your installation. Excellent product!

Thanks for commenting and Happy New Year!!! Al

How durable are those fittings for underground permanent applications for main sewer lines ? Are the seals tight enough to prevent tree roots from coming in ? Will the clamps rust overtime ?

[TheOldkid888]

@Dicofole Hello;

These fittings have been around for sometime now. The clamps are stainless steel and the rubber is a neoprene. Excellent product. As far as roots go;you should have no trouble especially if the clamps are tight and the pipe is well supported underneath. You could also look at MJ Couplings as well for underground that have a stainless steel band that covers the entire coupling. I have used 100's of them underground.

Hope this helps! Tks for commenting! Al

@TheOldkid888 I appreciate the info and will keep that in mind next time Al...Have a great one too! Patrick

@chaotic719playa Hello Patricio;You actually should use 2 ferncos if you are replacing or installing a fitting or changing a piece of pipe underground as you have no movement in any direction for the pipe to move. If you cut out that section, place a fernco on either end, drop your fitting with a piece of pipe glued in either end and then drop it in place and slide your ferncos over the new pipe. Thanks for commenting and have a great day!!! Al
