Cherne Clean Seal Plug?

Inspector required plumber to put in the plug during rough in. Now I need to release it, but it has a tag with multiple danger warnings on it. Is it realy dangerous or can I just release the pressure from the valve like a tire valve stem?

danger is in filling it too high. can explode with a shrapnel type intensity! release air slowly to let water from test to pass. then release all air to remove.

The tags are CYA's to protect Cherne from lawsuits. If the water column in the pipe is very high, then you could get wet when releasing the plug, unless it is the type that screws into the tee's opening.

Sort of like the warning on McDonald's coffee cups, "Contents may be hot".

Hello, I'm new to this forum and would like to find out more info ref the Cherne Clean Seal Plug. My general contractor stopped working on my home addition. One of things that was done before he left the job was the plumbing which included tying the drain for a toilet, shower and sink into the exitsting waste stack. There is a Cherne Clean Seal Plug on the stack now. My question is does the clean-seal plug need to be removed before the new toilet, shower, and sink can be use? I would greatly appreciate any information including any particular on how to remove it.

Thank you all,

Do you mean should it be removed before tying new piping into stack¿ Well, yes or else it would block off the drain at that point.

Release any air pressure and remove the plug. It has a "balloon" inside the pipe which will restrict any water flow until it is removed.

Thank you all for the replies. I removed it and all is well now.
