No Hub Rubber mission couplings Code Violation or Not?

Plumbing Code Violations

No Hub Mission Couplings are Rubber sleeves that fit over your pipes  to be connected and is tightened with a hose clamp.  There are 2 types of Mission couplings Banded and Non- Banded.  Banded Couplings have a metal sleeve over the rubber coupling and non banded is just a rubber coupling with no metal sleeve around it.  If you hire a licensed plumber to do work for you they should know all plumbing codes in your area.
   
Non- Banded Mission Couplings                                               Banded Mission Couplings
                                               


Lets look at the positives of these products as a whole.

• These are both extremely flexible couplings that are well suited for tight spaces but the Non-Banded Couplings tend to  have slightly more flexibility.
• These Couplings create an excellent seal around pipes when tightened downed, regardless of pipe line up.
• The Stainless Steel banding clamps are the best protection against corrosion.  These clamps last for years with no noticeable corrosion whether under ground or in your home they are made of the best corrosive resistant material.  
• With a quality No-Hub rubber coupling the rubber is composed of Natural and Synthetic materials that are extremely Strong, Ductile, and Superior Weathering properties which means no dry rotting. 

So are these couplings CODE and Why?

The major concerns or risks of using these couplings.  Well under pressure the un-banded couplings can expand and possibly burst, leaking sewage.  As we all know raw aged sewage can be a huge health hazard that is not suited for people to be around.  The banded couplings on the other hand can with stand extreme pressure.  There are many different grades of  banded couplings that may withstand different pressure levels and applications.

So as far as the plumbing codes go, every local establishments have different requirements.  As a rule of thumb and many years of experience we know the un-banded couplings to be a code violation in most towns in Illinois.  So a skilled plumber will know your locals codes and if the are allowed.  In most cases these couplings are sufficient for low pressure drain systems.  As far as the banded couplings go there is still local codes that  may be against these types of connections.  The stainless bands can withstand extreme pressure & blow-outs and the numerous types of grades and applications.  Many of these banded couplings are approved for underground usage and are code approved.

Conclusion

In a nutshell your plumbing professional should be kin to your local plumbing code and should have a better sense of where and when these couplings should be used.  As I said though the un-banded are usually a code violation and the banded coupling are strong enough to be a code approved product.  If you are located in the Southside and suburbs of Chicago Illinois www.rcszaboplumbing.com will provide you with the best plumbing service at a reasonable price.
