Besides cutting out the vacuum wall inlets back body for repair.

Does anyone or several folks have recommendations for procedures and equipment for cleaning out clogs that are estimated 5-6 " up into the back body pigtail besides a coat hanger?

Also, the clogs are hard and does not permit vacuum suction to pass through.

Thank you in advance.

The NFPA 99 Code, does not cover this type problem or repair.

So, any thing you personal do, will be on your own.

The rule here would be to remove the blocked line and return the system back to the original engineered line size. If we are to believe Albert Einstein / and we use a fluid to thin out the proteases material, are we now just sending this material down the side wall of the vacuum tubing ?

Hi Patrick,

Start with some hot water in a large syringe.  Leave the adapter and syringe in place so the water stays in contact so soften the clog.  Then do your best with the methods you have been attempting already. 

Be sure to wear gloves and eye protection.  Always consider vacuum to be contaminated.

We can't afford to rip the walls out every time someone allows debris to be suctioned into the pipeline. 

Thank you very much for sharing your wisdom and experience.

I appreciate it!
