Securing drain pipe from shower through basement

[Yosemitebob]

So while packing up the basement I was moving containers in place and one hit the drain pipe from the sink(odd place to have it, but none the less) and I noticed the pipe moved quite a bit. Hmmm, not good. So my fix for this was using two 1 x 1 x ⅛ aluminum, angle iron cut about 18 inches long with a bend at one end to mount to the forward wall with a "U bolt" at the pipe end, each angle iron goes off at about 45 degrees from the pipe installed as hight as I can. This way I can still move things under the angle iron for storage. I also placed one piece of angle iron on the bottom with another U bolt attached around the lower part of the drain pipe and attached to the floor of the basement. I now have a very rigid drain pipe. I can hit it now and not worry about knocking it around and causing a leak. I will provide a picture sometime tomorrow or the day after. OK, so the first picture is the down pipe going through the basement floor deck. At that point it is secure but as you can see the top is not secured to anything. So as things hit it while moving it can loosen or even brake the pipe and/or joints. OK, one thing I have to add, do not tighten the U bolt tight to the ABS, it can crack it and/or break the joint. What I did was used a double nut, one behind the angle iron and then lock washer and nut on the outside of the angle iron and tighten it to leave a small amount of movement. Now something hits it, it will only move mage an ⅛" of an inch the way I set it up.

Sorry it took so long, but I just got the two pictures showing the bracing that I did uploaded to the thread.

Nice clean job!

Looks to be a solid install, is there any flex built into it?
I'm thinking about the wiggles and wobbles that occur during
the drive from one location to another. Although it doesn't have
your polished results I think I would have used some plumber's
tape;

Gives some built in flex and is easy to work with.

hankaye,
Yes there is flex. I put a nut either side of the angle iron to adjust the "U" bolt where I want it to stay. There is an ⅛" gap from being tight to the pipe. All I wanted to do was keep the pipe from being broke or breaking the seal by inadvertently moving objects in the basement by me or the ride. If something hits it now, it will move the ⅛" and that means it has vertical movement according to the trailer movement, if there is any at all.
If you use the plumbers tape you will have to go four ways and two of those directions will be pulling up on the pipe, I only went two ways which does no pulling on the pipe at all. I rounded all my corners and edges of the aluminum (and even polished it :D ) so no gotcha's.

Thanks for asking

Bob, I was thinking along the lines of how an airplanes wings were
engineered to flap so they wouldn't break off... the rv's have some built in
wiggle to them for pretty much the same reason. You appear to have it well
thought out.

re. the plumber's tape, I would have wrapped it and some anti chaff material around the pipe using the holes I'd have secured the tape to the pipe and
attached both ends to the wall on opposite sides of the pipe with a smidgen
of wiggle room.

Courses for horses kind of thing I reckon. Ain't it grand that we don't all think
alike ... how boring would that be???

:) Yes indeed, yours would work well too. I just had some left over aluminum that was asking to be used for something :D

Done Correctly! Simple and effective. I sure appreciate the manufactures leaving so many things half done, it gives us the opportunity to do things correctly. Very nice work!
