Just got the sanitizer bucket from our dishwasher at the restaurant. It was a 5 gal white plastic (#2) pail with the brand new lid and gasket from the replacement. The lid has a standard 2" screw opening offset to one end. There are probably very few scratches on the inside, as it's a setnforget system. I plan on running hose water through it for my next lawn flood to leech out any chemicals. Anyone see a problem using this as a primary?
