Very nice Martin, a demo of the Kiss principle. ;-)
a design goal also very useful in Stoves design.
http://en.wikipedia.org/wiki/KISS_principle
But you can't glue (HD)PE.
There are however a few alternatives that may even make it more simple,
especially to 3° worlders without plastic welding equipment.
- a simple garden hose can, e.g. with some rope or wire, held in that
position.
- a smaller 1" or less, HDPE pipe can be made real warm and bend in that
shape
( 4" going to be difficult I'm afraid. ). Heating can be done with
hot water, or the sun,
or piping the exhaust from a truck through it, or why not, use it a
time as a stove chimney. ;-)
If the curves tends to collaps during bending, fill the tube with
sand first.
- Make it in PVC rain or drain pipe then it can be glued, and those 90°
elbows
are stronger because they fit over each other instead of being but
welded.

Dear low-tech-fans of the list,
With my Wetterau-water-lever I want you, as you like, to share with me
a simple thing; to re-make it and have fun and comfort in its simple use.
From my side it is free to use and I think, if published in the
stoves-list, it will remain free.
I think it can be even useful under poor water-access. It can make a
minimal quasi "current-water" out of a bucket.
Some years ago I made an application for me to transfer water from one
drum to the next drum, without always re-filling the lever-tube.
It's just using simple all-known-physics in the simplest way.
Background:The history of the barometer (
http://de.wikipedia.org/wiki/Barometer )
My water-lever consists out of two on top connected barometers (type
Boyle). I propose to call it Wetterau-water-lever, because of the name
of the region where I live and where I use it for many years. -- I
could not call it after the small river ("Usa") which is flowing here
nor like the village (beginning With "Bad" ), because it is not bad.
And I don't feel as inventor, though I am proud of its simplicity. The
3 pictures attached describe clearly form and function. ( each picture
about 140 KB)
It is made out of PE-water-tube. The parts are cut out of the tube
with an iron-saw, then welded together with an electrical heat-gun,
armed with a welding-mirror. --You can do it with glue as well.
The first edition (picture with thick tube) is all in one line:
down-up-down-up.
The later editions have the ends bent in 60° angle out of the flat of
the upper part. The real end points in 90° direction to the long parts.
By that geometry one can fill up the water-lever, while it is laying
flat on a table. ( By the picture at one end there is a metal-tube
connecting, which can be connected to a hose).
The Wetterau-water-lever can stand up or be hanged-up without loosing
water.
It can be dumped with one end into a bucket, to tap water, but does
stop, always staying filled up for further use.
- You can use different plugs to stop water-flow or minimize the flow.
It could make some sort of "current-water" out of a simple bucket.
Connected with a hose with small holes and plugged end, it could be
used as micro watering for few plants.
Even if the lever runs out of water, when connected to a long
irrigation-tube it can be easily re-filled;
-but an additional aeration-tube can make that the lever is not sucked
empty.
My main intention was, to get water from one drum to the next, without
drilling holes into a drum, -which can possibly cause leaks.
Built it, have fun to share and tell how you transform it and
transform its application.
Regards
Martin
