I doubt you’ll collapse the tank. Previously it was tested with a 45 blower with out a relief valve at 24” hg and after 20 minutes they turn the blower off for rear it would damage the blower. Some guys pump from their small Tm tank to these using as holding tanks.
Comparing these tanks to a $30.00 tank is not even close to a fair comparison. You can’t buy the mounting breakers that come with the Mytee tanks for $30.00. Like comparing apples and oranges. These can be holding tanks or vacuum tanks. They are that strong.
I agree. And you’re pleased with your results. That’s good. Water lift sealed at the machine we have found does not necessarily translate to lift at the carpet that’s why I asked. Thanks for the information.
