Best Sewer Line Installation in Phoenix AZ

We discovered what seemed to be a leak in our shower wall.  We called Streckfuss and they sent out a technician to evaluate the issue.  He arrived as expected and checked our shower and ran the shower to determine if there was indeed a leak.  He didn't find one readily and indicated that it was probably in the wall and we would have to do a complete tear down and replacement.  Remember, he didn't discover a leak he just said that we needed a teardown.  He then stepped outside and called the office and returned with a quote.  His expert evaluation and discussion with the home office indicated that it would cost somewhere between $5,000 - $7,000 to teardown the shower, find the leak, repair the leak, and install a new shower.  We were shocked and told the technician we would get back to him.  We chose to call our Homeowner's Insurance for advice.  They suggested calling a second plumber and submit a claim if there was and issue.  We called a second plumber who came by and checked the situation and determined that nothing seemed to be wrong.  We explained to him that Streckfuss said it would require a teardown to find the problem.  The second plumber was skeptical and said give it a couple of days and let them know if it happens again and they'll come back to check.  The issue did not return and has not returned in three years.  Our shower is fine.  Our insurance company thanked us for getting a second opinion.  After reading other reviews Streckfuss seems to take this route with many of its customers.  Sad to think this is a standard operating procedure.
