Hey Peggy, I read in the archives that you recommend Trident 148 for the vent hose but SBO doesn't seem to have it in their online store. Am I missing it? Also, is 10 to 12 feet too long for the vent line? I'm replacing the old system and that's about the length of the vent line and I'd like to use the existing vent location but upgrade to the 1" hose and fittings.
