For many years, Orange County residents have put their trust in Positive Plumbing, Heating & Air. That's because they know they can depend on us to do the job right the first time and at a fair price. A main sewer line camera inspection isn't always necessary. But, if you have recurring blockages, this could be the most cost effective solution. Sometimes commercial drain cleaners and plunging aren't enough. When only a visual inspection can help determine the extent of the problem, we have the state of the art equipment and trained personnel to do the job right.
