secret killers in your drains. Part 2

Is Drano any good? No. Drano's not very good. Drano is very hard on the sewer system itself. You're more likely to cause more damage than good on a cast iron or even PVC system with Drano. Really? Absolutely. My best advice to a homeowner would be to go to the nearest plumbing supply house and ask for some Bio One. It's a very good product, which most plumbing supply houses offer. You can even buy it on Amazon. But things like Drano, bleach, it's not good for your plumbing system and you could even risk injury with something like that. Really? Absolutely.
