Theo, what if I lightly oiled the pvc before applying the RTV to avoid excessive adhesion that might make removing it more time consuming (while lightning cracks around my head)? If the sealant stays somewhat flexible might it not self seal when the vacuum begins?
Ryan, I still don't understand the Y connectors. Are they to function like a clean-out in a waste pipe?
B-ski, I'll think about sanding the fitting. Do you think it would possibly allow more air into the system?
