Many homeowners take the integrity of their home’s drain and sewer system for granted. As a result, when there’s a clog or the think is slow to drain or the toilets take a couple of flushes to go down, the homeowner heads out and buys some Drain-O. No big deal, right? Well, for one in every five homeowners, it ends up being a major problem. It doesn’t have to be if you have a drain camera inspection done when your plumbing problems aren’t cleared up with a simple drain cleaner.
