Some tm guys are using the m ytee Roto mold tank....
I believe it is holding up
Rick Aranda used to own El Toro TMs. He tested the Mytee tank with s 45 blower. He took off the relief valve to see if he could collapse the tank. At 24” hg for 20 minutes, he shut it down so he wouldn’t damage the blower. Very strong tank.

General information to Arm-Chair Engineers out there:

"Round plastic tanks are the strongest and most durable."

Not necessarily.

Many of the common round plastic tanks (and I am referring to generally round) used for chemicals (ex: 55 gal/35 gal) are pretty thick (ex: 3/16" thick) and those will cave in and implode under "extreme" vacuum without question. I know this from experience.

A much stronger design would be a Hexagon and one being 1/2" thick min. A square and/or round design can be very "iffy" over the short run, or long run at that.

just use 3/4 inch plywood and triple coat with water proof sealing paint, if you wanna get crazy coat with an epoxy over that. Simpson strong ties.

I had a huge utility sink made out of wood like this, 150 gallons with no supports in between.. held itself full of water no problem.

after all the coats on it in black you could hardly tell it was even wood.

I am having leaks with my 15 year old aluminum tank
I hear that the problem is called ionization????

When metal comes it contact with aluminum it causes pits or holes....

Used jbweld... but I think I'm gonna hafta get a new tank

Saltwater i.e carpet cleaning chems and aluminum (even 6061-T6) eventually give it up.... No way around it.
Yea.....
Didn't know this when I bought it.....

I was looking at coated metal tank but if it's not stainless it will rust too....

Need more feedback on the m ytee
R2d2 looking waste tank....

But looks like that's what I'm gonna get
 

keep it clean

Look up aluminum oxidation. It will give you a better understanding of whats happening to the aluminum tanks.

You should see what happens when contractors cap over todays pressure treated lumber with aluminum. It turns aluminum to dust. A job i was on last year the home owner insisted on it. Lol it wont take long.

Engineers will tell you that one of the strongest shapes is an egg shape. Especially when rotomolding poly. 90 degree corners are strong but the flat panels are very weak. Under vacuum power they will hold a deform so that even after the vac is turned off they show the stress. Most mold makers will tell you to stay away from flat panels.

"Egg Shaped" design certainly would be stronger than a round tank for sure; no question.

However, in this industry within our designs, we must also focus on the elimination of foam caused from incoming water/debris/soap recovery. Round tanks will cause a venturi effect and thus foaming will eventually find its way to the stack pipes and down the hatch! When I mentioned a Hexagon shaped recovery tank,(unlike a square tank) we found it to help eliminate or slow down the venturi effect.

Hexagon and even octagon tanks mimic round only with flat panels. Flats are a weak element in design. The closer you get to round the stronger. Most manufacturers have been able to keep water, debris and foam out of their vac motors regardless of the shape of the tank. The Mytee TM tank with its ribbed, round design is pound for pound the strongest vacuum tank in the industry.

So far I haven't heard any negative feedback from tm owners soon the m ytee tank.......

From my experience I woudnt suggest aluminum......

Stainless steel wud be the only other option for me.....
But wud be a pain to drill an apo......
Which is what I am trying to do

Anderson you can add a tee before the bottom drain valve and add a 2" stack equal to the top of the tank and run all electric and APO hose through it. No drilling in the tank at all and easy to seal.
