What is the maximum PSI a polyethylene 'tote' water tank can hold? ?
I am building an irrigation system, and I have an Plastic 100 gallon translucent poly tank that is square with skds on the bottom and top. It was previously used for holding and transferring used vegetable oil. For my irrigation system to work properly I need to find out if it will safely hold 70 PSI of air pressure. It looks like it would, I THINK it would. There is a molding seem in the middle all the way around which I thought I could wrap a tow strap around for added strength. I know they are not designed as pressure tanks, but surely someone out there knows what the breaking point of one would be?
this link shows what it looks like; http://www.gototanks.com/300-Gallon-All-Poly-Tote.aspx
Thank you very much for any help I can find.
