I have a Bev Air prep table that waxed up its second cap tube due to 2 leaks and 2 compressor failures. It was a royal pain to replace the cap on this box and I have heard there is a tool that pumps a piece of lead wire through a cap tube with a bottle jack type thing to clear blockages. If I can get the cap clear would it make sense to size the drier up to a C-052-HH from the C-032 I put in there originally to get the rest of the wax out and change to R414B. By the way, the failed compressor was installed by others and improperly evacuated and the old drier left in so I inherited this mess. I am trying to fix this economically so we don't have to just trash a unit with a new compressor. Is there some chemical cure or some magic that can be done?
