Hi all, I recently have CCTV scanned all the pipe network in my building. The plumber has found a crack each in the sewer and drainage pipe. He has provided a quote to replace the broken section and to conduct a CCTV scan (again). Does any one know if a 2nd CCTV scan is necessary? or could i ask him to requote without doing another scan to keep our cost down? The total quote is approx 4000 to fix and re-scan. Thanks in advance.
