OATEY 137303 Hercules® Gallon Hercules PT-BIO1™ 4 661000010422

No. The PT-BIO1 formula contains no acids, caustics, solvents or other harsh chemicals, and Oatey states it is safe for use in all types of drainage plumbing. That makes it usable in cast iron, PVC, ABS and copper waste lines without the pipe attack you get from an acid or caustic opener. It is a non-acid product, not a chemical drain opener.

It targets grease, fats and oils in drain piping. That is the kitchen and food-service problem: soft organic buildup coating the inside of a waste line and slowing it down. It is a maintenance treatment for drain pipe, not a product for hair, soap scum or a fully blocked line that needs mechanical clearing.

Yes. Hercules PT-BIO1 is USDA authorized for use in food processing plants and is certified Salmonella sp free, which is what lets a facilities or MRO buyer put it on the approved list for a commercial kitchen or processing floor. It is the reason this product gets specified over a generic caustic drain chemical in food-service accounts.

They solve different problems. PT-BIO1 is a non-acid maintenance product dosed into a line that is still flowing, working on grease, fats and oils over repeated applications to keep buildup from closing the pipe. An acid or caustic opener is for a stoppage that already exists and carries pipe and fixture risk. For a grease-heavy kitchen line on a scheduled program, the bio treatment is the right call; for a hard stoppage today, you want mechanical clearing or an opener.

Oatey 137303 is the gallon size of Hercules PT-BIO1, with a listed product weight of 9.375 lb. For a property manager stocking a janitor closet or a route tech carrying it between buildings, that is a single-hand jug, and one gallon is a bulk unit compared to quart bottles for repeat monthly dosing of the same grease line.

Oatey part number 137303, UPC 661000010422. That is the gallon of Hercules PT-BIO1 drain treatment, the number a distributor or purchasing desk should quote to avoid getting the quart size instead.

Milky white is the correct appearance for this product. A cloudy off-white liquid straight from the jug is not a sign of a bad batch or separation, it is how the bio treatment is supplied.
