Slow floor replacement

[toastie]

Working on putting the front trim piece on today. I learned a little trick, you can see the gap in the picture, what I did was to take the palm of my hand and layed it on top of the gap and then slowly, very slowly bend the piece back to take the gap out, then slowly worked myself around with the trim piece.

No, its original...........toastie

Before permanently setting the front trim piece, added Trempro 635 to the outside and after setting the trim piece sealed the inside.

Looking great Toastie

thats a great idea to stop water at each layer. I was surprised how many seams on ours weren't factory sealed (which I think led to most of the floor rot). Every horizontal, overlapped seam was not sealed, only end cap and verticle seams. Every one of them leaked. Made panel replacement easier (man that black stuff is hard to remove) though. Boy your belt trim is in great shape.

Decided to go with a inline Hygienic Self Sealing Waste Valves, has been approved for RV use in the US since early 2007. Dry sealing valve prevents the escape of odors from your waste system into your RV and eliminates the need for check vents. Can be used in a vertical application as well as horizontal. A couple of Class A builders are using them under kitchen sinks to allow for drawers below the sink.

A valvectomy, notice that the ribs must be down in a horizontal ass'y,

I really want to see some of your Pictures....from the 2008 range...on the door and windows. I get blank pages...GEF.2x2... Not JPEG. On the later pics that are JPEG it comes thru. Have we got a computer whizz available? Can I get these to show? I think your work is super and I'd like to use it as a guide in my next project.

These dry valves look pretty interesting and I am at the stage in my remodel where I am just about to re-plumb my entire drain system. I have a couple of questions about these valves as follows:

I can see that using these dry valves would eliminate the need for p-traps on the shower and the sinks in the kitchen and bath. I can also see that it eliminates the need for vents on the drains themselves. Is the need for additional venting on the gray water tank then completely eliminated?

Presumably I still need a vent on my black water tank since there is no p-trap on the toilet that I can replace with one of these gadgets. Is that a given?

Thanks,

Malcolm

Would you not need a vent to relieve the build up of gas? If the the tank is "sealed", then I would think back pressure would interfere with the one way valve.

Found this on YouTube, a couple of guys tested the backflow resistance of the valve. Perhaps you can visualize that as the backpressure increases it places more force on the membrane to remain closed. That is, as demonstrated in the YouTube video, until the backpressure becomes sufficient to force the entire membrane to reverse itself.

I have the same concern about backpressure. If you have a sealed tank with no external vent, then any fermentation in the gray water tank would exert backpressure on the downstream side of the valve and prevent free drainage of the shower.

A few inches of backpressure on the tank side of the valve could cause a few inches of backup in the shower.

Not a problem if you also have a regular tank vent. Or if you keep the pH of the graywater high enough to prevent fermentation.

Otherwise, might be a problem.

All of my tanks will be vented to the atmosphere, the shower will have its own gray water tank. The reason that I going with the Hepvo is space, I'm micro managing the space.

I was thinking some more about this and I think that you are right about still needing to vent the tanks.

Thinking about running the sewer hose through the sewer hose holder kit, then, permantanly fastening the hose to dump valve and design it that the kit can pivot. Any other ideas out there with pictures?????

That's is a great idea, I knew that there had to be something out there in this multi billion dollar rv business, thanks for sharing.
