Yarome Posted November 25, 2015 Report Share Posted November 25, 2015 How well do those waterless traps really work? I'm not as concerned about odors, but it would be kind of nice to 'streamline' the under-sink storage areas and do away with the check valves. My main concern is how well do they "pass through"? Adding any kind of 'restriction' in my drain line tends to make me worry about the need to use more water, but I have no experience with them. So what's the skinny?

57becky Posted November 25, 2015 Report Share Posted November 25, 2015 Other than an occasional cleaning to remove crud, ours have been working fine. There is one mounted vertically from the shower drain, and the other is mounted horizontally under the bathroom sink. They seem to do the job, with no odor problem. The rig is a 2012, so they are holding up well. Link to comment Share on other sites More sharing options...
Mark and Dale Bruss Posted November 25, 2015 Report Share Posted November 25, 2015 These traps have been used in Europe for years. It is taking time for building codes to allow them in the US. Link to comment Share on other sites More sharing options...
Jack Mayer Posted November 25, 2015 Report Share Posted November 25, 2015 I've used them several times over the years in non-RV installations. They have all performed as expected. I would not hesitate to use them in an RV. In the Spring I am building two outdoor kitchens and will use them in the sinks. Link to comment Share on other sites More sharing options...
budeneighe Posted November 25, 2015 Report Share Posted November 25, 2015 I have been interested for a long time but have held off because of the possibility of mineral buildup on the mating surfaces. I have seen this on the toilet valve and on the air venting caps under the kitchen and bathroom sinks. Those have rubber flaps and both have gotten crusty buildups over long times. I suspect each person's experiences are going to be different depending on what water refining equipment they have on all their incoming shore water. Water softeners would certainly be a help in some RV parks. Link to comment Share on other sites More sharing options...

Water softeners would certainly be a help in some RV parks. I solved all those issues in my rig by installing a whole house RO system. While it is not for those who want to "set and forget" it, the results are outstanding. Once Gregg gets the updated video on his channel I'll post a link. In the meantime, here is a link to the design paper for those interested. Link to comment Share on other sites More sharing options...
