Heated Under belly area

[yddad45]

I opened my underbelly yesterday to fix a water leak I've had when I used my black water flush. One thing I found interesting is upon inspecting a heating duct pipe I found that there was a T pipe fitting that allows heated air to blow inthe under belly compartment. I have always used electric space heaters in the winter time in my old RV but now that I know that the underbelly area actually has ducted heating I will probably use the heat in the Rv more often to prevent pipes freezing and it will also be more comfortable with heat circulating in the underbelly area.
I also fixed the leak, I just used a better pipe thread dope on the nipple that attaches the water line to the black water spray flush. It was leaking were it screwed into the tank.

If the temps are below freezing for several hours each day that is a good idea. If you use electric heaters some of the heat will go down so it will take a pretty good freeze to cause problems.

Yddad45, I have seen several posts where people have had trouble with leaks at the connection there. Just curious which brand of sprayer do you have. Is this problem inherent in the design I wonder? Is there an option to crimp this connection? Thanks

I had black water flush installed from Jayco, not sure type of flush they use. It leaked during first outing, took it back for repair, it started leaking again second time out, decided to look at it myself, it was a simple fix, don't know why dealer or factory used so thin of a thread sealer. It felt like glue-it was that thin, anyway it's fixed now. Sometimes it's just better to do it yourself and you know what you get. No crimp connection that I know of, you just need to use a good pipe thread sealer.
