THRIFT T-600 Alkaline Based 6 lb. Granular Drain Cleaner 2 Pack

This product was recommended to me by a licensed plumber. At least twice a year I would have issues with my sewer line from the house to the main. When it clogs-up its REALLY CLOGGED, and takes an hour or more to clear. I have been using this product for approximately 3-years for monthly maintenance. I have never had a slow or stopped-up drain since. Some may think that it is expensive, but, IT IS WELL WORTH THE PRICE. You can buy this product at a plumbing supply warehouse, however, Wal-Mart has the BEST price. I save approximately 30.00 dollars by buying it online at Wal-Mart. The delivery time was actually earlier than expected, as it appears to be shipped from the manufacturer. It did take about 1 week to receive it, so you would want to make sure you have some already on hand for any emergency. You CANNOT put this product directly into the toilet, only the sink and tub drains.

Used one entire bottle but it did not open drain. Ended up calling plumber and spent $225.00 to unclog grease in drain. So the $$100.00 I spent on these two bottles went down the drain
