Grey Holding Tank Drops

[Redwood2013]

Has anyone had their Galley grey tank drop about 3"?

Galley grey tank was full. It buckled and felled off the steel ledge it was resting on. Service guy coming out to put back in place and use extra straps to hold it up and in place.

No..... BUT someone just posted somewhere the other day about his black tank dropping. This is unacceptable quality control at the factory as far as I'm concerned. Sorry about your problem. I'm awaiting repair of a serious leak issue on my bedroom slide on our 5 month old 39MB but that's another story.........

How did you know it had dropped? I worry about this a lot. I know they are heavy, and after I learned about how they are installed, it certainly gives one reason to be concerned... We try to never travel with full tanks, even though this is UNREASONABLE. We typically allow our black tank to become full before emptying it (while we are parked).

I heard a loud noise, then the underbelly cover dropped down and water started run out. I was outside about to pull the grey tank valve. It all happen right in front of me.


Tank was hanging down on one end, I could push the tank up by hand. Also noticed the level indicators probes were not in proper position, in other words, probes 1,2 & 3 were on the same level due to the tank had dropped.

Wow, thanks. Seems like welding a little more reinforcement in the frame for these tanks would be a good idea and cost nearly nothing. Once again, cutting corners. :-(

These tanks sit on 2 1/2" angle iron that runs the width of the frame. Similar to the cross members that were in another post showing the broken welds. There is nothing tying these supports in so the weight of the full tank can spread them and down it comes. There needs to be cross members welded between them to hold them together or banding installed around the tank and cross members. My grey tank has the banding on it but not the black when I contacted Redwood about my tank I also told them of this novel idea to eliminate this problem

"Crank those units out...as fast as possible as "time is money" & if something fails, we can worry about it later ONLY IF they file a warranty claim". Most be mgts. motto.

As Christain had said on another thread....according to the factory, these units are designed to travel with all tanks filled. Hopefully these are isolated instances. As the redwoods age, if the welds start giving out, it will be a disaster for the company.

The fixed was to move one end of the 2.5" angle iron that holds up the tank so the tank was a snug fit. Drilled new holes about 3/4" inside the old holes. Tank now fits tight on the angle iron. Also, while I was repositioning the angle iron, moved the angle iron up 1/2" to allow tank better drainage to the drain valve.

Were the ends of the angle irons held in with self tapping hex head screws? Most rv manufacturers install them that way so it is possible to replace a tank and do maintenance like replacing probes, etc. It seems that most don't get them spaced correctly and tight enough. Some used to install with 1/2" plywood underneath so tanks wouldn't bow so much.

Each end of angle iron had 4 self tapping hex screws.

Mine are tack welded in place. A piece of banding going around the tank and cross members would be a cheap fix or a bolted cross member to hold the 2 pieces of channel the tank sits on would work as well
