Get rid of the "P"-trap

I recently saw this mentioned in the FMCA magazine and found it quite interesting. The new Hepvo Valve replaces the standard P-trap under sinks and does not allow odors or gasses to enter the living area. Best of all because there is no water needed for it to work you don't have to worry about the P-trap evaporating dry. It was mentioned in the article that the valve makes more under sink room by eliminating the P-trap and can be mounted either vertically or horizontally and still work. It also does away with typical venting requirements.

For those of us that have bathroom sinks plumbed to the black water tank I can see this as a great product. Even if you just want to add more room under your sinks it might be worth looking into.

Must be the "type" of valve that is used with those "green" waterless urinals at some of the state and federal parks.


Neat idea.

I find that those waterless urinals tend to stink - literally. Nice to save water and all, but that system still needs improvement, IMO. It is sort of like not flushing the toilet, to rinse off what is on the porcelain bowl. It still smells. Randy

Ummm, I don't think these valves are meant to be used on toilets, they are in lieu of a P-trap on sinks and showers.

I wonder if it would actually pass code in the US?

The FMCA article stated that several RV manufacturers are already using them. I believe it is probably the higher end units as I am sure they aren't as cheap as using a P-trap.

It looks like just a simple check valve and I recall reading a few reports of these things failing so they have their faults as well. It seems more like a solution looking for a problem. Making sure water is in the trap is pretty easy, fool proof and happens automatically every time you use it.

Hmm, funny as the picture in the FMCA magazine didn't look like just a simple check valve at all. I really don't see this as a check valve in the sense you think of. demonstration. There are several that show it and how it works. Also one that shows testing it with a column of water till it fails, Took quite a bit, I was surprised.

There is also a discussion of the valve by a group of RVrs that have used it here The valve was developed in 2007 from what I can find and from what the gentleman in post 11 of the discussion points out there had been no reported failures of them as of 2009. If water was to back up against it, it actually just closes tighter.
