On a newer RV, what do I do if I do not want to alter the roof membrane by removing the factory supplied base?
The siphon lid is so well engineered it will actually convert the factory installed cap into an odor extractor. This modification works well on 3 of the most common cap bases. The “Universal lid” will enable the standard base to function almost 80% aw well as the whole Siphon. • Will the Stack Cap work on my house? In some cases it can work extremely well. It depends on the problem you have, but if on those windy days that sewer odors are present, its almost certain the Siphon Stack Cap will work. Also works well on outhouses. • Will the Stack Cap work on a composting toilet? Composting toilets are designed to draw off the moisture by venting out through the vent stack. Down drafts and extra moisture or rain is definitely not wanted. The Siphon stack cap does both as well as keeping out other airborne debris.
