I seem to remember that some time ago you mentioned a source for
"elbow" fittings for 1.5" sanitation hose with a smooth, easy radius
instead of a sharp 90 degree turn. The new design of our head plumbing
is going to require some elbow fittings. Is the sharp radius something
that I should be concerned about and, if so, would you mind providing
a link to your recommended source?


Cindy, Unless there are a lot of 'em, I don't see a problem with using
elbows. However, if you feel you'd be better off with radius fittings,
SeaLand has 'em...you'll find 'em all he
http://www.sealandtechnology.com/pro...ges.asp?pid=66 (scroll down
the bottom of the page for line drawing illustrations).

It's not obvious from the drawings that all these "kits" are made up of
components that are PVC cemented together. For instance the 90 radius
"kit" # 307230311 is actually 3 pieces--the radius #307341161 + 2 hose
adapters # 307341513.

However, you can get every part EXCEPT the hose adapters from just about
any hardware store that has a decent plumbing department for about 1/3
SeaLand's price...all the radii, wyes and tees are standard PVC plumbing
pieces. So the only thing I'd order from SeaLand are hose
adapters...you'll need two for each fitting.

Smooth bore radius curved elbows can more easily be snaked out. Make
your own endoscope from garden hose!

If you are going to shop for plumbing at a builder's supply, I
suggest looking for certified approved Mechanical Joint (MJ) elbows.
They are smooth radius, and include single hose clamps, or
possibly double, if you shop enough, I guess. I have used several,
here and there. Some may be cheap knock offs, and some clamps may
not be all stainless. The ones I have used at home and in the boat
are near indestructible flexible rubber and properly installed,
provide a smooth interior bore, overall. Caution. UL seals can be
counterfeited, too.

I Don't have intimate knowlege of all the hoses in the world, so
cannot know if your hose needs adapters. The MJs I have used clam
pretty tight to round pipe and hose as well as oval, indenting
themselves into what I consider to be trustworthy connections even
without glue, and easy to use and dissassemble for maintenance. I
prefer hose clamps with hex head screw tensioners. Inspect regularly.

Pun intentional, couldn't resist. Guilty. Desolé.

I tried to pull such a joint apart, and could not. I was gonna hook
it up the the bumper hitch and try, but decided it was pointless.
Besides, the truck wouldn't fit in the freight elevator on the boat.

Your risk! Vigilance! Reef early! Poland forever!
