Plumbing woes

[Leroy Eckert]

Jimmy,
I have installed natural stone flooring over the flat electrical elements. The
installation is much easier because a mud bed either dry packed or lightweight
concrete are not required. I've never considered PEX in an RV flooring
application but I think it could be done. Frankly, it's hard to believe it would
be cost effective. It would require planning and grooving or elevating the sub-
floor to accept the 1/4" tube.

Preparing the substrate for the flooring installation is critical.
Deflection/movement will break stone particularly if butt joined. If I were to
attempt the installation I would use a backer board and an antifracture membrane
before tile. Floor elevations and weight are also a consideration. I have tile
in my bus without cracked grout joints. It has cement grout. Someone did it
right. I've seen several coaches with marble, none butt joined.

Regarding solar, it would only work in daytime hours. Electric, gas or diesel
boilers would be needed at night.

I understand from posts on this forum that Ernie Ekberg installs flooring in
coaches. I'm certain he understands the deflection theory and has experience in
coaches.

I specialize in very high end homes installing natural stone inlayed with wood,
granite, marble and mosaic. I address deflection issues daily.

When my grandkids are outa here, I want to install a travertine floor inlayed
with oak in my bus. I think I can make it work. However, I will keep my
Wabasto diesel fired hydronic heating system. Thanks for asking.

Leroy,

What about installing it in an RV?? Small solar collector on the roof for
a direct daytime heat. I have seen the flat electric type, but that would
require some shore/gen power.

I had the opportunity last year to install marble flooring over PEX on and
off grade. The first floor was not a problem. The second floor was a
different animal. Light weight concrete was used off grade and did not meet
deflection requirements for the selected flooring. I used a special
antifracture membrane with heat resistant characteristics to do the job. I
might add, without warranty. So far, so good. I think it is a great product
if it is used to spec. Unfortunately, plumbers do not warranty flooring.
The home is in Mountain Village, Telluride, CO. Very expensive joint.

My neighbor who lives across the street from our Mammoth Lakes house is
the
plumber that did that episode of This Old House and the radiant heating
using
PEX tubing. He loves the stuff, and can't understand why anybody wouldn't
use it. He's working on the contract for heating the new runway at Mammoth
Lakes Airport, using PEX plumbing and radiant heat. Pretty neat
stuff....pretty neat how all that radiant heating stuff works both inside
and outside. If
you get a chance to see that episode of Bob Vila's This Old House, it's
worth
the watch.
