I was looking into ways to reduce the expense of running my DC system around the shop. The hose gets pretty pricy and, seemingly, for no good reason other than they feel they have us by the cajones.
I found that the corrugated plastic piping they have at Home depot fits the standard 4" DC connectors pretty darned well. And a 10' piece is less than $6! My question and concern is the corrugated interior.
Is this ok to use for the vertical runs? I'd be a little hesitant to use it for the horizontal runs across the shop. It may be too prone to trapping dust and small chunks. But, is it ok for the horizontal runs or should I stick to using rigid, non-corrugated piping for the horizontal runs?
I was planning to use this foam air seal beading stuff to help seal the connections better then use regular DC hose clamps for the fastening at the connectors. The beading fits into the grooves nicely. I figure if I ring the insides of two or three of the grooves to act as O-rings it should seal fairly well onto the connectors.
Any advice? Is this a good or bad idea? Where can I and can I not use this type of hose in my runs? Of course, I am referring to the NON-perforated hosing, not the drain field type with all the slits along it.
Any ideas, advice and/or voices of experience would be much appreciated.
