Foam board would be easy to cut/form wedges out of to support the tank.

I have a 1 3/4" wide strip of 1/2" marine plywood that appears to fit perfectly on the sides, cut in half it will be just long enough to do the job.

I am not sure if that would be better or worse than foam board.

I would send recpro the pictures and ask if you can get a new one that’s better and won’t take forever to arrive. And if you can’t, then maybe the wood shims. Or even foam rubber.

Honestly, I think you're worried about nothing. You're going to anchor it down somehow, probably metal straps would be the easiest. But a ratchet tie downs would work as well. If it pulls down straight (and I expect it will} forget about it

I would support it securely with hard foam or wood. It's going to be stressed/under tension if you flatten it or let it flatten. Use it in it's current relaxed shape, support it the way it is, don't force it.

There is a good chance you are correct but the thought of 50+ gallons leaking inside my van has me concerned. I have not addressed the issue of mounting the tank yet...ratchet straps are a great idea!

The sides of the tank were sitting nicely on the 1/2 " plywood when the tank was full, now that it is empty it rides up 1/2" on the left side.

I could pull the ends down 1/4" each and call it good.

 

[free2roam]

Something like this

The left side is not as easy with the 1 1/2" protrusion on top.

I did find a use for 2 factory tie down rings on the front side. Think this will work? It would be nice to proceed with my build 😀

Curious,
Does that type of plastic relax and change shape if heat is applied or does it have a memory?

 

[free2roam]

A little research tells me it has no memory.

Sorry - the images were slow to load - I think that looks great !!! Best of luck.

I did hear back from recpro, they are in contact with the supplier and had me send them more photos showing the tank dimensions, they also wanted to know where my drain was located. Hopefully this will be resolved shortly.

 

[free2roam]

Recpro finally got back to me on my water tank, the manufacturer said that the tank was perfectly flat and square when it was shipped to me but it must have become distorted while being shipped over the mountains and they will not be making me a replacement, their final statement was that the tank will weigh almost 500 lbs and with that amount of weight bouncing around in the back of my van something will flatten out. Thanks Recpro and Alpha tanks, next time I am shopping for quality parts I will know where not to go.

🤔

“Shipping Over the Mountains Distorted the Perfect Tank” ??

I’m sorry you had this experience with them ,,, They will be off my list of possible vendors if they treat customers like that. I suppose the “We will not be responsible for over mountain shipping distortion” warning that is in large bold print on their website is what they rely upon ,,, oh they don’t have that caveat on their website 🤔

Did you fill it with real hot water, then let it cool overnight with weight on top over the ends? I bet it would lay down and stay put after that.

 

[Lolaeliz]

500 lbs! I imagine whatever distortion it will surrender.

It is time to address my tank and water supply, I plan to use 3/4" pex for the supply side with a 3/4" drain installed to drain straight through the floor after the shut off valve.

I have 2 questions at this point, should I use a flexable section of tubing after the shut off valve to allow for movement and what to do for supply lines? Can I make my own out of reinforced vinyl tubing?

That is what I did “vinyl tubing”

FYI the plastic male threads on the water pumps also like RV plastic females. I just used the RV style, vinyl tubing, & hose clamps.
