10/16/2020 Confirmed customer had a blockage in the mainline due to all fixtures in the house not draining. Pulled toilet and used cable down drain line clearing out paper blockage. Used camera in drain line verifying drain is clear to the city sewer. Drain line is compromised of cast iron so gave customer pricing to install clean out on the location of previous blockage. Thank you for choosing CPI Plumbing and Heating.
