Polyethylene tanks (LDPE) as sump

[waltee1000]

Has anyone used these polyethyene tanks as sump? These tanks are being sold as tanks that meet FDA standards. I am think of getting several and connecting together using bulkheads to make into a big sump.

Not as a sump but i have a tall tamco that i use to hold water and have never had an issue with it. They make pretty good stuff IMO
