Roto-Rooter sells drain care products that technicians keep in their work trucks. All winter long they are driving around with frozen bottles of this stuff. It says on the bottle, do not let freeze. Yet your paying over $50 per bottle. You can buy the same stuff at home depot for $20.
Not to mention one of the Boston Managers brags about how he used to use drain care bottles to urinate in. When the bottles were full he would "treat customers drains" and then charge the cost of the product!!
Be Very Wary of these guys.
Oh, and ive seen another manager drink it.....
